Domain takedown: What is it, and why does it matter?

What is a domain takedown, and why does it matter?

Summary: A domain takedown is the process of removing or disabling a domain involved in malicious activity. Read on to learn why domain takedowns matter.

While the internet provides countless opportunities for businesses to reach a wider audience, it also opens the door for malicious actors looking to use a brand’s good name to exploit its unsuspecting customers. One effective way to combat this threat is through a domain takedown — removing harmful websites that could potentially damage your brand’s hard-earned reputation and put users at risk. In this article, we’ll go over what a domain takedown is, why it’s necessary, and what actions a business should take to protect its reputation and customers.

What is a domain takedown, and why is it important?

A domain takedown refers to the process of removing or disabling a domain name associated with illegal, fraudulent, or malicious activity. Typically, the takedown process involves the business reporting the harmful domain and working with the hosting provider or domain registrar to take it offline.

Cybercriminals often use names of well-known brands to gain a victim’s trust. These fake sites often use the same or similar logos and designs to look like the real deal and trick people into giving away passwords, credit card info, and personal details or even charging them money. For example, a scam site like “amaz0n-support.com” could easily fool someone into thinking it’s Amazon customer service. Many people could get scammed if that site isn’t taken down quickly.

As more organizations and individuals rely on the internet to conduct business, the number of businesses targeted by fraudulent websites continues to grow. According to research[1], in the last quarter of 2024 alone, almost 989,123 unique phishing websites were detected — almost 6% more than the previous quarter and 13% more than Q2.

Domain takedown is an important measure in fighting online threats. It helps to protect a brand’s reputation and users from phishing, malware, and other types of domain abuse.

What types of domains are subject to takedown?

Domains can be taken down for a variety of reasons, usually when they’re involved in harmful or illegal activity. As a company, it’s important to be aware of harmful domains that could put your brand, your customers, or your network systems at risk. Here are some of the most common types of domains that can get flagged and taken offline:

  • Phishing domains. Domains that are designed to trick users into giving away sensitive information like passwords or credit card numbers. Most of the time, they try to mimic legitimate websites to appear legitimate.
  • Malicious domains. Sites that are hosting or delivering malicious software such as ransomware, trojans, or spyware. While simply visiting a malicious site typically won’t infect your device, especially with an up-to-date browser, these domains often use tactics like redirect chains, drive-by downloads, or exploit kits to deliver malware.
  • Fake store domains. Domains that are used to deceive users through fake services, offers, or products. They aim to steal data or money by pretending to be something they’re not.
  • Brand impersonation domains. Domains that are misusing brand names to trick consumers into thinking they’re interacting with a legitimate business. They often host stolen or pirated content, violating intellectual property rights. A lot of the time, these domains rely on typosquatting or slightly altered spellings of real domains (like “amaz0n.com” instead of “amazon.com”).
  • Illegal content domains. Sites that are hosting content that violates laws, such as stolen data, pirated media, explicit content, or other prohibited materials.
  • Spam and scam domains. Sites used for mass spam campaigns, phishing attacks, and other fraudulent schemes. They’re often part of larger campaigns.

Reasons for domain takedown

Domains can be taken down for various reasons, including but not limited to:

  • Copyright violation. Using copyrighted material like text, images, videos, or software without permission.
  • Trademark infringement. Impersonating a brand or using a company’s name, logo, or identity in misleading ways that create confusion.
  • Fraudulent activity. Running scams, collecting payment or personal information under false pretenses, or setting up fake services.
  • Malware distribution. Hosting or distributing malware, spyware, ransomware, or tools that enable data breaches and other attacks.
  • Violation of hosting terms. Engaging in harmful, abusive, or restricted activity that breaches the provider’s policies.
  • Illegal activity. Publishing or linking to prohibited material such as child exploitation, terrorist content, or criminal activity.
  • Cybersecurity threats. Facilitating phishing, hosting stealer logs, or exposing users to different types of data breaches and unauthorized access.
  • Violation of local or international law. Domains involved in legally prohibited activity, like fraud, identity theft, or money laundering.

Steps to address suspicious domains

When you come across a suspicious domain, whether pretending to be your brand or spreading harmful content, it’s important to act quickly. Acting fast can prevent scams, protect your customers, and limit damage to your brand. Here are the necessary steps to investigate and take down malicious or fraudulent domains.

1. Analyze domain details

Before taking action, collect as much information about the domain as possible. This information can include details about where the domain is registered (the registrar), records of who owns it, related IP addresses, and active website content. If the domain is hosting a live website, review it carefully. Check for signs of phishing, malware, or brand impersonation.

2. Evaluate the potential risk

Not all suspicious domains pose an immediate threat, so conducting a risk assessment is necessary. Determine whether the domain is hosting phishing websites, distributing malware, or attempting to trick users into thinking it’s your brand. Consider whether it could confuse customers, damage your reputation, or be used in fraudulent transactions. Domains that look very similar to yours or use your branding should be treated as a high risk.

3. Document and collect evidence

You’ll need solid proof to support any takedown requests:

  • Screenshots that show how the domain is being used maliciously.
  • WHOIS records and DNS information to find out who owns the domain and where it’s hosted.
  • User complaints, phishing reports, and real-world examples showing how the domain has caused problems.

This evidence will help when reporting the domain to service providers or authorities.

4. Report to the registrar

Once you have sufficient evidence, the next step is to report the domain to its registrar. Most registrars have an abuse contact or form for this purpose. When reporting, you should:

  • Include all the evidence you’ve collected, especially anything that shows the domain is breaking laws.
  • Clearly outline how the domain is being misused, like pretending to be your brand, running phishing attacks, or spreading malware.
  • Follow up if you don’t hear back in a reasonable amount of time. Some registrars can be slow to respond.

5. Notify the hosting provider

If the domain is hosting harmful content, report it to the hosting company. Hosting providers often have strict policies against phishing, malware, and fraud. When submitting a report, be sure to:

  • Provide specific URLs and evidence of the infringing content.
  • Reference the hosting provider’s abuse policies that prohibit malicious activity.
  • Request action, such as the removal of the offending content or account.

6. File a UDRP complaint

If the domain is using your trademark, consider filing a UDRP (Uniform Domain-Name Dispute-Resolution Policy) complaint. This process, handled through domain arbitration organizations like WIPO, can help remove the domain. You’ll need to show:

  • Proof of trademark ownership.
  • Evidence that the domain was registered and used in bad faith.
  • Evidence that the domain is confusingly similar to your trademark.

7. Submit a takedown notice

If the domain is using your copyrighted materials (like your logo or content), you can file a DMCA (Digital Millennium Copyright Act) takedown notice. You can send it to the registrar and the hosting provider. DMCA is typically faster than UDRP but only applies to copyrights, not trademarks.

8. Report for malicious activity

In addition to contacting registrars and hosting providers, you should report fraudulent domains to cybersecurity organizations, which can blocklist them and warn users. Reports can be submitted to:

  • Google Safe Browsing.
  • Microsoft SmartScreen.
  • National cybersecurity agencies or anti-phishing organizations.

9. Monitor the changes

Even after taking action, keep an eye on the domain. Bad actors often make changes or switch hosts to continue their attacks. Ongoing monitoring helps you catch these threats earlier next time.

Common issues occurring in the domain takedown process

While domain takedown is important to protect your brand’s reputation and keep your customers safe, the process isn’t always smooth. Challenges can come up that slow things down or make it harder to get results fast:

  • Slow response times. Registrars and hosting providers may take days or even weeks to process a takedown request, especially if the domain in question is hosted on shared servers or is registered through an international registrar with different time zones or procedures. In many cases, the investigation process can be slow because service providers need to verify the complaint, assess the evidence, and contact the domain account owner.
  • Legal jurisdiction barriers. Domains registered in different countries may be harder to take down because of different laws and regulations regarding domain takedown requests. For example, a phishing domain registered in a country with weak cybercrime enforcement or no strong intellectual property protections might be difficult to take down if local authorities do not have the necessary jurisdiction or resources to pursue the case.
  • Repeat offenders. Malicious actors often don’t stop after a takedown request is successful. Repeat offenders will sometimes attempt to register new domains under slightly altered names or use a different registrar or hosting provider to continue their malicious activity. They might even re-register the same domain once it expires, bypassing the original takedown and creating a continuous cycle that can be difficult to break.
  • Lack of evidence. It’s important to present all necessary evidence to increase the chances of a successful takedown. Registrars and hosts may reject takedown requests without clear and sufficient proof.
  • False positives. Legitimate domains can sometimes be flagged incorrectly because of misinterpretation of evidence, confusion over similar domain names, or incorrect assumptions about the domain’s purpose, which may lead to legal disputes. It’s a particularly sensitive issue when dealing with trademarks or intellectual property. If a domain uses a name that is similar but not identical to your brand, you can face legal challenges regarding whether the domain constitutes infringement or not.

Best practices for preventing abusive domains

Taking down fraudulent domains is necessary to protect your brand and customers. However, by taking steps to prevent these issues, companies can lower the chances of facing malicious domains and handle problems more easily when they come up. Here’s how your organization can stay prepared.

1. Choose a trusted domain registrar and enable privacy protection

The first step in securing your domain is picking a reputable registrar. Not all of them are equal, so look for one that has solid security practices, a good track record, and responsive customer support in case something goes wrong.

Once you’ve registered your domain, enable privacy protection. Without it, your domain’s contact information, like your name, email, and phone number, is publicly listed in the WHOIS database. Hiding this information can make it more difficult for attackers to target you.

2. Strengthen your domain’s login security

Your domain is only as secure as the account protecting it. Use strong, unique passwords that are hard to guess, and turn on two-factor authentication (2FA) wherever it’s available. It’s important to secure all accounts associated with the domain, like those for your hosting provider or DNS manager.

Keep an eye on your account activity, too. Some registrars offer alerts if a login is made from an unfamiliar location or device — turn them on so you’re never caught off guard.

3. Prevent unauthorized transfers with domain locking

Domain locking is a security setting that prevents your domain from being transferred to another registrar without your permission. If someone tries to hijack your domain and move it elsewhere, the lock stops them in their tracks.

This feature is usually called “registrar lock” or “transfer lock,” and it can usually be enabled through your registrar’s dashboard. Enabling it is a small step that can help you keep control of your domain.

4. Protect your domain’s integrity with DNSSEC

DNSSEC, short for Domain Name System Security Extensions, ensures that the information returned from your domain’s DNS query is authentic and hasn’t been tampered with, thus helping to prevent DNS spoofing and man-in-the-middle attacks. This way, you reduce the risk of visitors being redirected to fake or malicious sites when they type in your web address.

Without DNSSEC, attackers can exploit vulnerabilities in the DNS infrastructure and potentially spoof or hijack those DNS requests, redirecting visitors to fake or malicious websites. Enabling DNSSEC helps protect your users from those kinds of threats and keeps your domain’s integrity intact.

5. Maintain long-term domain security and ownership

Security isn’t just a one-time setup. It’s something you have to maintain over time. Always renew your domain before it expires to avoid losing it. Many registrars offer automatic renewal services, which help ensure that your domain is never accidentally dropped or expired.

Also make sure your contact information is always current. The registrar needs to be able to reach you if it ever encounters an issue with payments or suspicious login attempts.

6. Use NordStellar’s threat exposure solution to monitor threats continuously across all top-level domains

Even with strong domain security, threats can still slip through the cracks. NordStellar’s threat exposure platform helps your team spot attacks before they become full-blown incidents. It includes solutions like data breach monitoring, account takeover detection, session hijacking prevention, and dark web monitoring that help you act quickly and stay protected.

Cybersquatting detection, in particular, monitors threats across all top-level domains and uses AI analysis tools to detect and assess suspicious domains. You’ll receive real-time alerts with in-depth insights, including screenshots, redirect chains, WHOIS data, and similarity metrics, so your team can quickly investigate and resolve harmful domains. This way, you can help protect your brand, prevent phishing, and retain customer trust.

What is typosquatting? Definition, risks, and how to prevent it

What is typosquatting? Definition, risks, and prevention

Typosquatting is a growing cybersecurity threat that businesses can’t afford to ignore. As companies increasingly rely on having a digital presence, cybercriminals exploit common URL misspellings to deceive users, steal sensitive data, and damage brand reputation. These fraudulent domains can lead to financial loss, regulatory risks, and a breakdown of customer trust. In this article, we’ll cover what typosquatting is, how it works, its risks, and the steps businesses can take to stay protected.

What is typosquatting?

Typosquatting is a social engineering technique that targets internet users who mistype a website address. Attackers register misspelled or lookalike domain names of popular sites, then use these alternative websites to trick users into revealing personal or financial information or downloading malware. For businesses being impersonated, such fake websites can erode trust, damage reputation, and lead to financial loss if customers fall victim to scams under their name.

The “typo” part comes from the small mistakes people make when entering URLs. A classic example is goggle.com, a web address users may type instead of “google.com.”

How does typosquatting work?

Typosquatting works by exploiting human error: typos, spelling mistakes, and visual misinterpretations of website addresses. Attackers register lookalike domains and use them for various schemes, including:

  • Phishing: Attackers create fraudulent websites that mimic legitimate ones to trick users into entering their usernames, passwords, or other sensitive credentials.
  • Malware and adware: Visiting a fake website may result in the installation of malicious software, which can compromise devices, steal information, or display intrusive ads.
  • Redirects: Users who visit these lookalike domains may be unknowingly redirected to other sites filled with advertisements, affiliate links, or unwanted content.
  • Fake digital products: Cybercriminals use lookalike domains to sell counterfeit or unauthorized products under a well-known brand’s name, deceiving customers.
  • Data harvesting: Fraudulent websites can collect personal data, including credit card details and other sensitive information, for identity theft or financial fraud.

An alternative website often mimics the real site, using an identical logo, branding, and layout to appear legitimate. Users who don’t notice the difference may unknowingly hand over valuable information.

Types of typosquatting

Cybercriminals manipulate domain names using different techniques to mislead users. Here are the most common types of domain typosquatting.

Misspellings and typos

The simplest technique relies on common typing mistakes. An accidentally misspelled domain name can lead to a fraudulent website instead of the one the user intended to visit. Examples include:

  • gooogle.com instead of google.com
  • facebok.com instead of facebook.com

Attackers take advantage of these errors to direct unsuspecting visitors to scam websites, malware pages, or ad-heavy pages designed to generate revenue.

Homoglyph attacks (lookalike characters)

Homoglyph attacks swap characters that look nearly identical to the human eye, creating deceptive but convincing web addresses. Some examples:

  • rnicrosoft.com (using “rn” to look like “m” in microsoft.com)
  • g00gle.com (replacing “o” with zeros in google.com)

These subtle swaps are effective because users often don’t notice the difference, especially on smaller screens or at a quick glance. Once on the fake site, visitors are likely to enter their credentials, thinking they are on the real website.

Extra characters (prepending/appending)

Typosquatters manipulate web addresses by adding extra letters, numbers, or words to closely mimic legitimate domains. Even a small change can go unnoticed, especially if users aren’t paying close attention. Examples:

  • amazonn.com instead of amazon.com
  • realtors.com instead of realtor.com

Turning a singular domain name into a plural or adding a single letter is often enough to deceive users. These lookalike domains are often used for phishing scams, malware distribution, or ad fraud.

Hyphenated domains

Adding hyphens between words may make a domain appear legitimate at first glance. Most popular websites don’t use hyphens in their main domains, so cybercriminals exploit this trend to create misleading alternatives. Examples:

  • net-flix.com instead of netflix.com
  • apple-support.com mimicking a legitimate Apple support page (support.apple.com/)

Users scanning a URL quickly may assume it’s a genuine site, only to end up on a phishing website or a page filled with deceptive ads.

Missing-dot domains

Missing-dot domains look nearly identical to legitimate website addresses but omit or add a dot in critical places. These subtle changes are easy to miss, especially when users type URLs quickly or rely on autofill. Examples:

  • financeciti.com instead of finance.citi.com
  • chickenfarm.fences.com instead of chickenfarmfences.com

A missing or misplaced dot can lead users to phishing sites, malware downloads, or deceptive ads.

Alternative spellings

Spelling variations can also be used to trick users into landing on a fake website. Typosquatters exploit regional differences, such as American and British English spellings, to create misleading domains. For example:

  • favorite.com vs. favourite.com
  • colorcode.com vs. colourcode.com

Businesses with internationally recognized brands need to be aware of these variations and secure key domain versions to avoid losing traffic — or worse, exposing users to scams.

Wrong domain endings

With countless top-level domains available (.com, .co.uk, .net, .org, .shop, etc.), typosquatters take advantage of users assuming they are on the right website when they’re not.

One of the most common tricks is using .co instead of .com — Colombia’s official domain extension — since it closely resembles the world’s most popular TLD.

Other examples include:

  • brandname.org instead of brandname.com
  • popularshop.web instead of popularshop.shop

To prevent typosquatters from fooling their client base, companies often register multiple domain variations to block squatters from capitalizing on these minor but effective differences.

What is the purpose of typosquatting?

Scammers register misspelled or lookalike domains for different reasons — some for financial gain, others for more malicious purposes. Here are the most common motivations.

Cybersquatting

Cybersquatting refers to the practice of registering, selling, or using a domain name with the intent of profiting from someone else’s trademark. A common tactic involves typosquatting, where slight misspellings of popular domains are registered to mislead users or pressure companies into buying them.

Getting clicks or views

Typosquatters often create fake websites filled with misleading ads, low-quality content, or even malicious links. They’re designed to attract accidental web page visitors and generate advertising revenue for each click.

Earning money from affiliate links

Sometimes, a fake site redirects traffic to the real company’s website through affiliate links. The squatter earns a commission from the brand’s legitimate affiliate program, effectively monetizing users’ mistakes.

Redirecting traffic to competitors

A typosquatter may create a “related search results” listing and use its traffic to benefit rival businesses. When users land on the deceptive domain, they’re shown search results or ads leading to competitors. These businesses pay the typosquatter per click. Again, this tactic monetizes accidental visitors at the expense of the original brand.

Bait-and-switch scams

In this scheme, attackers create fake websites that closely resemble real e-commerce or service sites. Victims pay for items that never arrive or services that never materialize. This practice, known as website spoofing, is designed to look as authentic as possible — until the buyer realizes they’ve been conned.

Stealing personal information (phishing)

One of the most dangerous uses of typosquatting is phishing. Attackers create fraudulent login pages for popular websites, such as banking sites, social media platforms, or online stores. A user lands on the malicious site, enters their credentials, and unknowingly hands over their account access to cybercriminals. This stolen data is then used for fraud or identity theft or sold on the dark web.

Spreading malicious software

Some typosquatted sites are designed to infect visitors’ devices with malicious software. These fake websites may:

  • Trick visitors into installing fake antivirus software that locks a device until a ransom is paid.
  • Use keyloggers to track passwords and sensitive information.
  • Deploy spyware to monitor online activity or steal financial details.

Damaging a brand’s reputation

Attackers may create fake domains that host harmful, misleading, or defamatory content, linking it to the targeted company. Users who land on these sites may see false claims, offensive material, or fake products, which are all designed to erode confidence in the real brand.

Parody and satire

Not all typosquatting is malicious. Some domains are set up as joke sites that poke fun at existing sites, well-known brands, public figures, or organizations. While these alternative websites are usually created for humor, they can still damage reputations or spread misinformation, especially if users mistake them for the real thing.

Who is typically targeted by typosquatting?

Typosquatting affects individuals, small businesses, and large corporations. Attackers exploit human error, using deceptive domains to steal data, spread malware, and erode trust. The most common targets include:

  • Corporations and their employees. Large companies are prime targets — attackers often exploit lookalike domains to impersonate corporate websites and internal portals. These fake websites are often used for phishing attacks, distributing malicious software, and supply chain fraud.
  • Small businesses. Unlike large corporations, small businesses often lack dedicated cybersecurity teams or resources to monitor for typosquatting attempts. Attackers take advantage of this situation by creating malicious websites to deceive customers, steal sensitive data, or tarnish a brand’s reputation. This attack often has devastating consequences for smaller companies.
  • Everyday internet users. Anyone who types a website URL into their browser is a potential target. A single misspelled web address can lead to a fake login page, malicious pop-ups and scams, or even financial fraud.
  • Mobile users. Typosquatting is even more effective on mobile devices, where smaller screens make it harder to spot URL differences. Plus, autocorrect can modify URLs in unexpected ways, sending users to fake sites.

Risks associated with typosquatting

While not every typosquatted domain is created with malicious intent, many of their owners do act in bad faith. Typosquatting can cause serious security and financial risks, especially for businesses:

  • Data theft. Fake sites can deceive users into entering sensitive information such as login credentials, credit card details, or personal data. This stolen information can then be used for fraud or identity theft or sold on the dark web.
  • Phishing attacks. Attackers design lookalike malicious sites to steal login credentials, often targeting banks, email providers, and corporate portals. A single typo can lead users straight into a phishing trap.
  • Distributing malicious software. Fake websites may prompt users to download a “security update” or software that is actually malware. Once installed, this can spy on users, steal data, or even lock systems for ransom.
  • Brand reputation damage. Malicious typosquatter’s sites can be used to spread misinformation or sell counterfeit products.
  • Financial loss. Businesses can lose revenue when customers fall victim to fake websites.

Real-world examples of typosquatting attacks

Typosquatting has been used in various cyberattacks, targeting both individuals and organizations. Notable typosquatting examples include:

  • PayPaI phishing attack (first active in mid-2000; resurfaced in 2011, 2012, 2017, and 2020). Attackers registered paypaI.com, a domain nearly identical to paypal.com, replacing the lowercase “L” with an uppercase “i.” Unsuspecting users who mistyped the URL were directed to a fake website mimicking PayPal’s login page. Many had their credentials stolen and later had to deal with unauthorized transactions.
  • Fake credit reports (ongoing since 2003). Following the launch of AnnualCreditReport.com, dozens of similar domains with intentional typos were registered. These fake sites deceived visitors into providing sensitive financial information, leading to identity theft and credit fraud.
  • Last Week Tonight (2016). Comedian John Oliver registered typosquatted sites like equifacks.com (Equifax), experianne.com (Experian), and tramsonion.com (TransUnion). Unlike malicious actors who use typosquatting for deceptive or harmful purposes, Oliver’s intent was purely educational. He used these examples to humorously and effectively highlight the security vulnerabilities associated with typosquatting, demonstrating how easy it is to register misleading domains and raise public awareness about the issue.
  • Icelandic national police phishing (2018). Cybercriminals registered logregIan.is, cleverly replacing the lowercase “L” with a capital “I” to mimic logreglan.is, the official website of Iceland’s national police. This fake site was used to run phishing attacks, compromising personal and financial information.
  • US census scam (2020). Ahead of the 2020 US census, multiple typosquatted domains were registered to mimic the official Census Bureau website. These fake sites were used to harvest personal information from unsuspecting visitors and spread false or misleading information about the census process.

Typosquatting exists in a legal gray area — its legality depends on intent. Some businesses register typo domains for defensive purposes to protect their brand, which is perfectly legal. But when typosquatting is used for fraud, phishing, distributing malicious software, or impersonation, it becomes illegal.

Typosquatting is a subset of cybersquatting. While cybersquatting involves registering domain names that mimic legitimate websites — often to resell them for profit — typosquatting specifically targets internet users who mistype URLs, using misspellings or lookalike characters to create fake websites.

In the United States, the Anticybersquatting Consumer Protection Act (ACPA) makes it illegal to register or use website addresses that are confusingly similar to trademarks with the intent to profit from or mislead users. The law was created to stop individuals from hoarding trademarked domain names to sell them at a high price.

To comply with ACPA, domain owners must prove they are acting in good faith and not misleading users or violating trademark rights.
Internationally, the Internet Corporation for Assigned Names and Numbers (ICANN) enforces the Uniform Domain-Name Dispute-Resolution Policy (UDRP), which allows trademark holders to challenge typosquatting and cybersquatting cases. If a domain is found to be registered in bad faith, it can be transferred or canceled.

How can businesses prevent typosquatting attacks?

Typosquatting puts businesses at risk of phishing scams, data theft, and reputational damage. Here’s how companies can stay ahead of attackers and protect their brand:

  1. Secure domain variations. Register common misspellings, hyphenated versions, and alternate spellings of your domain. Purchase relevant top-level domains, such as .com, .net, .org, and country-specific extensions, to prevent bad actors from misusing them. Redirect the misspelled domains to your official website.
  2. Monitor for typosquatted domains. Use domain monitoring tools, such as cybersquatting detection, to detect and receive real-time typosquatting alerts when suspicious domains appear.
  3. Use SSL certificates to signal trust. SSL certificates prove your website’s authenticity and protect user data. When a site has a valid SSL certificate, browsers display a padlock icon in the address bar and “https” in the website address, confirming that the connection is secure.
  4. Secure your email from impersonation. Attackers may use typosquatted domains to send phishing emails in your company’s name. Protect your organization by:
  5. Implement anti-phishing measures. Train employees to spot phishing domains, especially in emails, chat messages, and online searches. Deploy email security solutions to block phishing attempts before they reach inboxes.
  6. Encourage direct website navigation. Use bookmarks, QR codes, or mobile apps to reduce reliance on manual web address entry. Alternatively, encourage employees to use safe search tools instead of typing URLs directly into their address bars.
  7. Get suspicious websites and mail servers taken down. If typosquatting affects your business, report and take legal action for a domain takedown.
  8. Notify stakeholders. If an attacker is impersonating your business, inform your customers, staff, or other relevant parties immediately. Encourage them to look out for suspicious emails or fake websites.
  9. Use a threat exposure management platform. A security platform like NordStellar provides proactive domain monitoring, alerting businesses to typosquatting threats before they cause damage.

Session fixation vs. session hijacking attacks: Prevention and the main differences

Session fixation vs. session hijacking attacks: Prevention and the main differences

Session fixation and session hijacking are two major threats that exploit vulnerabilities in web application session management. These attacks allow cybercriminals to take over user sessions, potentially gaining unauthorized access to sensitive information. Since session identifiers (IDs) serve as the key to maintaining user authentication, they become a prime target for attackers. In this article, we’ll break down how session hijacking and session fixation work, highlight their key differences, explore other session-based threats, and discuss best practices to defend against them.

What is session hijacking?

Session hijacking is a type of attack where hackers take control of an active user session by stealing and exploiting the session ID. The session ID is a unique token that identifies the user and maintains state across requests, often stored in cookies, passed in URLs, or embedded in hidden form fields. In session hijacking attacks, once the attacker obtains the session ID, they can access the user’s account without needing credentials, allowing them to read sensitive data, make unauthorized changes, or escalate privileges. Timing is critical in these attacks, as session IDs are only valid for a limited period.

How session hijacking works

Session hijacking exploits weak points in how web sessions are managed. A typical session hijacking works like this:

  1. A user logs in, and the server assigns a session ID, usually stored in a cookie or HTTP header.
  2. An attacker intercepts or guesses the session ID using methods like packet sniffing, cross-site scripting (XSS), or malware.
  3. With the stolen ID, the attacker creates requests that look legitimate and bypasses the login process entirely.
  4. Now, acting as the user, they can steal data, change settings, or escalate privileges. This step is especially dangerous in business environments.
  5. Session IDs can be stolen through unsecured Wi-Fi, infected endpoints, exposed query strings, or insecure web apps vulnerable to cross-site scripting. Even systems using HTTPS aren’t immune if the session management is sloppy. That’s why effective session hijacking prevention solutions are key to securing web applications.

Real-world examples of session hijacking

Session hijacking attacks have been used in high-profile breaches. One early example was Firesheep, an extension for the Firefox browser released in 2010, which allowed anyone on the same network to hijack sessions of users logged into sites like Facebook or Twitter over HTTP.

More recently, attackers have targeted internal business apps by injecting session-stealing scripts into vulnerable web portals. That led to a full account takeover, access to sensitive internal systems, and data breaches.

What is session fixation?

Session fixation is a type of attack where the attacker sets the session identifier before the victim logs in. When the user authenticates with the same session ID, the attacker can reuse it to access the session without needing credentials. This exploit takes advantage of poor session management practices, such as not regenerating session IDs after login.

How session fixation works

A session fixation attack typically follows this process:

  1. The attacker generates or obtains a valid session identifier from the target application (usually from a login or pre-login page).
  2. They get the victim to use the same session ID. The specific technique depends on how the application handles session IDs. It could be via a link with the ID embedded or a fake site that passes it through.
  3. The victim logs in using that session ID. If the application doesn’t regenerate the session ID after login, the attacker now shares access to the authenticated session.
  4. With that user’s session ID, the attacker can interact with the app as if they were logged in themselves.

Session fixation attacks rely on weak session management — specifically, accepting session IDs from untrusted sources (like URLs or form data) and failing to issue new IDs after login. If a system lets one user set or reuse another’s session ID, it’s vulnerable.

Real-world example of session fixation

A session fixation vulnerability was discovered in Schneider Electric’s EcoStruxure™ Power Monitoring Expert (PME). In this case, the system allowed a session ID to be set in advance via the login URL. An attacker could send a specially crafted link containing a predefined session ID to a victim. If the victim logged in using that link, the attacker could then use the same session ID to access the authenticated session — effectively hijacking it without needing to steal credentials or intercept tokens. This attack highlighted how improper session handling can lead to serious security breaches, even in industrial and enterprise environments.

Session hijacking vs. session fixation: The main differences

Both session fixation and session hijacking take advantage of improper session management and have a similar goal: gaining access to a web server session ID. However, they differ in the way that attackers achieve this end goal.

In a session hijacking attack, the attacker waits for the user to log in and then steals the session ID to slip into the existing session unnoticed. In a session fixation attack, the attacker tricks the user into using a predetermined session ID.

Let’s see how session hijacking and session fixation compare side by side:

Factor

Session hijacking

Session fixation

Attack complexity

Moderate to high

Low to moderate

User interaction required

No (passive attack)

Yes (requires tricking user)

Prevention difficulty

High (requires encrypted communication and token security)

Moderate (requires session regeneration and validation)

Impact severity

High (can lead to full account takeover)

Moderate (depends on session handling by the application)

Attack vector

Network sniffing, XSS, malware

URL parameters, shared cookies, insecure login flow

Session ID exposure

Token is stolen

Token is fixed before authentication

Exploitation scenario

Public Wi-Fi hijacking, malware injecting session-stealing scripts

Phishing attacks, insecure login flows

Affected systems

Web applications, APIs, mobile apps

Web applications with weak session management

Other session-based attack types

Beyond session fixation and hijacking, several related session attacks exist. While not always identical, they often overlap in risk and impact.

  • Session predictions. The attacker guesses or predicts valid session identifiers based on weak generation algorithms. This can be surprisingly effective if session tokens follow a pattern or are not randomized properly.
  • Session replay. In this attack, the attacker captures a valid session request and replays it later to impersonate a user. It often overlaps with hijacking, especially in API-based applications.
  • Session spoofing. Here, an attacker manually crafts session data or headers to impersonate a session, typically when session validation is weak or token structure is predictable.

These techniques are often chained with session hijacking or fixation to gain access, escalate privileges, or maintain persistence. If your session handling is weak, attackers will find a way in.

 

Risks of session-based attacks for businesses

Session-based attacks are a serious threat because they target one of the core mechanisms nearly all web applications rely on: session management. The fallout can affect everything from customer trust to regulatory standing.

Direct risks

These are the consequences when an attacker gains control of a session:

  • Data breach. Hijacked sessions can expose customer data, financial records, or internal documents.
  • Account takeover. The risk of account takeover is especially dangerous in admin or privileged user accounts.
  • Financial theft. A session hijack in e-commerce or banking platforms can lead to unauthorized transactions.

Indirect and long-term risks

Even after the attack is over, the damage often continues with:

  • Legal compliance violations: Under GDPR, PCI DSS, and other regulations, failure to secure session data can trigger fines or audits.
  • Reputational damage: Customers lose trust quickly when unauthorized access or data leaks are reported.
  • Incident response costs: Time, resources, and recovery operations after an attack can be significant.

How to protect against session hijacking and fixation attacks

Most session-based attacks come down to poor session management. The fixes aren’t complicated, but they need to be implemented consistently.

Here’s how to secure the sessions of your web application:

  1. Regenerate session IDs after login. Always create a new session ID once a user logs in. This invalidates any pre-authentication tokens and neutralizes session fixation.
  2. Use HTTPS. Encrypt all traffic using HTTPS, ideally with HSTS enforced. Without it, session IDs can be intercepted in plaintext.
  3. Use long, random session IDs. Generate random session tokens with enough entropy to prevent guessing or brute-force attacks.
  4. Enforce strict session ID expiration and rotation. Short expiration times and inactivity timeouts limit how long a stolen session ID is useful. Regular token rotation closes the window even further.
  5. Monitor for anomalies. Track unusual session behaviors — like simultaneous logins from different IPs — and respond automatically (such as change the session ID or request re-authentication).
  6. Harden your code against XSS. Most session hijacking begins with script injection. Sanitize inputs, use CSP headers, and audit third-party scripts.
  7. Avoid embedding session IDs in URLs. Use session cookies or secure headers to pass session data. Never expose tokens in URLs or redirect parameters.
  8. Educate users. Help users spot phishing attempts and avoid clicking suspicious links, especially in environments with shared access (such as public computers or libraries).

Even with all the right precautions, session-based attacks can slip through. That’s why security monitoring and automation matter.

Account takeover vs. identity theft: Differences explained

Account takeover vs. identity theft: Differences and prevention

Account takeover occurs when a hacker gains unauthorized access to someone’s account, while identity theft occurs when a criminal steals someone’s personal information to impersonate them. Scammers typically carry these crimes out through phishing attacks and data breaches, but the full list of methods for stealing accounts and identities is much more extensive. These crimes are particularly dangerous because account takeover can lead to identity theft and vice versa. Read the article to learn more about the differences between account takeover and identity theft.

What is account takeover?

Account takeover (ATO) is when a hacker takes control of someone’s account using stolen login details. These stolen usernames and passwords often come from shady places on the dark web, where criminals buy and sell them after getting these login details through social engineering, data breaches, or phishing scams.

What is identity theft?

Identity theft happens when someone steals a victim’s personal information and uses it without their permission. They opt for full names, addresses, financial details, Social Security numbers, and medical insurance data. Once thieves have it, they can commit fraud, open up new financial accounts in the victim’s name, or make unauthorized purchases.

What’s the difference between account takeover and identity theft?

Account takeovers happen when an attacker steals someone’s account, while identity theft involves a criminal stealing someone’s personal data to open new bank accounts, commit fraud, or make purchases without their knowledge.

The table below provides some more perspective on the differences between account takeover fraud and identity theft.

 

Account takeover

Identity theft

Definition

A cybercrime where attackers steal an individual’s account to extort data or money.

A crime when attackers steal personal information to impersonate someone or commit fraud.

Target

Bank accounts, email accounts, or social media profiles.

The victim’s identity, including Social Security numbers, banking details, and personal address.

Methods

Phishing, brute force and MitM attacks, credential stuffing, social engineering, exploiting weak passwords, session hijacking, malware, and data breaches.

Phishing, data breaches, dumpster diving for sensitive documents, physical mail theft, social engineering, fake websites, public Wi-Fi snooping, and malware.

Goals of attackers

To gain access to the victim’s account for data theft, malware distribution, financial theft, or fraud.

To exploit the victim’s credit, open new financial accounts, make fraudulent purchases, or obtain government benefits.

Consequences

Financial loss, identity theft, legal trouble, unauthorized transactions, and difficulty regaining access to accounts.

Emotional distress, financial losses, ruined credit score, legal issues, and damaged reputation.

Recovery

Changing passwords, alerting service providers, and monitoring the account for further suspicious activity.

Reporting the theft to authorities, contacting financial institutions, freezing credit, recovering personal information, and sometimes working with identity theft protection services.

Prevention

Using strong, unique passwords, enabling two-factor authentication (2FA), monitoring accounts for unusual activity, and being cautious of phishing attacks.

Regularly checking credit reports, using credit monitoring services, shredding sensitive documents, using a VPN to protect your data online, and being mindful when sharing personal information.

How does an account takeover happen?

In account takeover fraud, criminals target all sorts of accounts — email, social media, financial, cloud storage, HR systems, and other internal corporate accounts that hold sensitive data and require a username and password to get in.

To steal accounts, hackers usually use credential stuffing, phishing, or brute-force methods. In credential stuffing, for example, they take advantage of the fact that people often reuse passwords, trying login details from previous data breaches on different accounts. Phishing is when attackers impersonate someone trusted to extort sensitive data from victims. Brute force attacks, on the other hand, use automated tools that keep guessing passwords until they hit the right one.

As soon as a stranger gets into someone’s account, they change passwords and email addresses or even add their own multi-factor authentication (MFA) device. If that happens, getting an account back might become a nightmare.

Let’s take Uber as a real-life example. In 2016, attackers took over a contractor’s account with access to an internal Uber network. The breach exposed the personal information of over 57 million users and drivers. The hackers even demanded ransom from Uber to keep the breach quiet.

Signs of account takeover in businesses

Red flags that signal an account takeover fraud include:

  • Unusual account activity. Logins from unfamiliar locations or at odd hours might indicate that someone’s trying to gain unauthorized access to your business account.
  • Changed account details. After hackers get unauthorized access to a victim’s account, they often change account information, like emails, phone numbers, or even passwords.
  • Suspicious emails. Another red flag is out of the ordinary emails asking you to reset passwords or provide sensitive information. These usually are phishing emails designed to compromise user accounts.
  • Unauthorized transactions. This one’s a dead giveaway. If an attacker gains access to your financial account, they might start making unauthorized transactions to unfamiliar accounts or make fraudulent purchases using your money.

What are account takeover risks for businesses?

Account takeover attacks might hit businesses hard. After hackers get hold of employee or customer accounts, they always opt for as much as possible — they steal sensitive information so later they could sell it on the dark web, they commit fraud under a victim’s name, or even lock you out of your own systems.

One of the main goals of ATO for criminals is financial profit, so the immediate financial loss after an account takeover can definitely be overwhelming. However, the long-term damage to your brand’s reputation and customer trust can be even more emotionally distressing.

 

How does identity theft happen?

Identity theft happens when criminals get their hands on an employee’s sensitive data, such as credentials or financial information. They usually extort this information through phishing and social engineering attacks or by exploiting system vulnerabilities. With this stolen data, they can impersonate the employee to make fraudulent transactions or access systems.

In 2020, attackers breached Ubiquiti Networks’ systems and stole employee credentials. They accessed company servers and demanded a $2 million ransom. The most outrageous twist was that the attacker turned out to be a Ubiquiti insider who tried to cover up his malicious deed by whistleblowing about the breach. This caused a 20% drop in the company’s stock price and raised questions about the enterprise’s internal security. That’s a clear reminder that stolen identities lead to serious trouble — from data breaches to public fallout.

What are identity theft risks for businesses?

Identity theft isn’t just something that causes problems for individuals. It can have serious consequences for businesses, too.

The more on-site, freelance, or remote workers you have, the bigger your attack surface. Which means that if an attacker steals your employee’s identity, they could get unauthorized access to your company’s assets, carry out phishing and social engineering attacks, and disrupt your business operations.

Imagine a hacker steals your company’s tax ID or business registration details — this could let them impersonate your brand. Criminals might trick suppliers into sending goods to their addresses or trick your customers into transferring them money. That would cost you a hefty sum of money and your reputation.

How can businesses prevent account takeover and identity theft risks?

The more of these tips you incorporate into your account protection routine, the safer your company’s systems will be.

  • Use strong password policies. Make sure your team uses tough to crack passwords. Strong passwords should mix upper- and lower-case letters, special characters, and numbers.
  • Implement multi-factor authentication (MFA). MFA is an extra layer of security to your employee’s accounts. Even if a hacker manages to steal your employee’s passwords, they won’t access the accounts without their smartphone or biometrics.
  • Monitor account activity. Watch what’s happening inside company accounts. Weird log-in times or connections from unfamiliar devices might signal that a stranger is trying to access your data.
  • Educate employees about security practices. Make sure your team is armed with all the information about the most common security risks. The more they know, the less likely they’ll make mistakes that could let attackers into your systems.
  • Limit access to parts of the network. Not everyone needs access to everything. Limit access to parts of your network to those who actually need it for their job. It will help contain the damage in case of a data breach.
  • Implement lockout mechanisms. Set up automatic lockouts after a certain number of failed login attempts. This will make it harder for hackers to brute-force their way into user accounts.

We’ve got something else besides the above methods to prevent account takeover and identity theft. NordStellar is an advanced threat exposure management platform designed to detect cyber threats targeting your company. It runs vulnerability assessments and finds system flaws that could lead to account takeover fraud or identity theft, giving you time to respond to emerging risks.

Enterprise cybersecurity: What it is and how to manage it

What enterprise cybersecurity is and how to manage it

Enterprise cybersecurity is an area your business should prioritize to protect against cyberattacks and data exposure. But before you create a cybersecurity plan, you need to understand what threats you’re protecting against. In this article, we’ll explain what enterprise cybersecurity is, review the specific cyber threats that target businesses, and explore how to safeguard your company.

What is enterprise cybersecurity?

Enterprise cybersecurity is the application of strategies and security measures for managing the risks an organization faces on the digital front. It also involves the use of specific technologies to protect an organization’s IT infrastructure and data.

An effective enterprise cybersecurity strategy shields local networks, cloud assets, and remote devices, keeping them resilient from cyberattacks. It ensures safe access to company infrastructure for all employees, including remote workers, by applying specific measures, such as firewalls, encryption, security protocols, and intrusion detection systems (IDS).

With the right security measures in place, the IT team gets alerted about suspicious activity that might indicate a cyberattack or data breach, so it can take action to investigate the threat and secure the system. For example, a company might use an IDS to detect and alert security teams about any unusual network traffic that could indicate an attempted cyberattack. But enterprise cybersecurity involves more than just passive protection — it’s about proactive strategies and a quick response.

What is the difference between enterprise cybersecurity and general cybersecurity?

Enterprise cybersecurity focuses specifically on protecting the IT infrastructure, data, and networks of businesses or large organizations, while cybersecurity in general applies to all types of digital security measures, including those for individuals and smaller entities.

Why is enterprise cybersecurity important?

Enterprise cybersecurity is crucial for any company that wants to succeed. Without adequate safeguards, a company risks disrupting its operations, damaging its reputation, and losing its competitive edge. Enterprise cybersecurity practices ensure business continuity by proactively protecting from cyber threats and data leaks, as well as building customer trust.

Enterprise cybersecurity benefits

Protection from cyber threats

Enterprise cybersecurity plans and programs address different impacts of cyberattacks and are crucial for several reasons, including:

  1. Network and cloud security. Firewalls and intrusion detection systems protect your network infrastructure and cloud services from unauthorized access and potential breaches. For example, zero trust architecture treats every user and device as untrusted until proven otherwise, meaning each access request is constantly verified to ensure it’s secure.
  2. Data protection. Encryption and secure access controls ensure the confidentiality and integrity of sensitive information, both in transit and at rest. For example, end-to-end encryption in communication between employees and clients secures the sensitive data while it’s being transmitted over the internet.
  3. Endpoint security. Security solutions on all employee devices accessing the company’s network prevent malware infections and unauthorized data access, which is especially relevant with the rise of remote work. An example of endpoint security is the deployment of mobile device management software, which allows IT teams to monitor, secure, and manage employee devices. If an employee loses their work laptop (or if it gets stolen), the IT team can wipe its data remotely to protect proprietary information from unauthorized access.
  4. Security awareness training. It’s important to educate employees on how to recognize phishing and practice safe online behaviors. For instance, implementing simulated phishing campaigns to test employees’ ability to identify fraudulent emails helps raise awareness and reinforces safe online practices, effectively reducing the chances of successful account takeover attacks and identity theft.

Protection from data leaks

A data leak can expose sensitive information and damage your company’s reputation, so effective cybersecurity measures are a must.

Data leaks might happen for different reasons, like simple human mistakes, weak security measures, or intentional attacks. For example, a misconfigured database might grant public access to sensitive data, or an employee might mistakenly send confidential files to the wrong recipient. To avoid such incidents, your company should implement enterprise cybersecurity strategies, including:

  1. Data loss prevention (DLP) policies set clear guidelines on data handling, access controls, and sharing protocols. These policies define who can access specific data and under what circumstances to minimise the risk of accidental exposure.
  2. Awareness training. Human error is the leading cause of data leaks. Regular training sessions can help employees recognize phishing attempts, understand the importance of data confidentiality, and empower them to follow secure data handling practices.
  3. Data-centric security measures include the application of technologies that protect data itself, regardless of where it resides. This approach ensures that even if data is accessed without authorization, it remains unreadable and secure.
  4. Data breach monitoring and auditing data access can help detect unusual activity, such as unauthorized access attempts, and make it easier to take quick action.
  5. Secure third-party interactions ensure that vendors and partners follow strict data protection rules. Since data leaks often happen through third-party connections, it’s important to regularly check and monitor their security practices.

Increased customer trust

When a business proactively protects sensitive data and systems, customers feel more confident and are more likely to view the brand in a positive light, which typically translates to brand loyalty.

What is a data breach in the eyes of your customers if not a betrayal of their trust? Studies show that effective security measures significantly influence customer trust and behavior. Providing high-quality customer experiences and ensuring data protection can lead customers to trust the brand 4% to 10% above average. In contrast, poor security can lead to a decline in trust, with customer trust dropping by 20% to 53% below average.

T-Mobile’s investment in cybersecurity is a good example of the importance of protecting customer data. Following previous data breaches, the company has been strengthening its security measures, including adopting a zero trust security model and implementing multi-factor authentication (MFA). These efforts aim to rebuild customer trust and set a standard for industry security practices.

While implementing cybersecurity practices in your company and building customer trust can be a long and challenging journey, knowing the specific threats you’re up against helps you focus your efforts on the most critical areas and makes the process much more manageable.

Most common cybersecurity challenges for enterprises

The challenges that can threaten the security and integrity of your business operations come in all forms and sizes. Some of the most common cybersecurity challenges include:

Malware

Malware is malicious software designed to damage or gain unauthorized access to systems. It ranges from viruses to spyware, and it often enters the system through infected email attachments or vulnerable software. For example, the very common infostealer malware can infect your device via a phishing email and steal your sensitive information, including login credentials that the attacker might later use in an account takeover attack.

Ransomware

Ransomware is a type of malware that locks or encrypts a company’s data and demands payment to restore access. It’s easy to get your device infected with ransomware if you’re not careful because ransomware groups, which are often behind these attacks, often deliver this threat via phishing emails or insecure websites.

APTs

Advanced persistent threats (APTs) are prolonged and targeted cyberattacks that skilled hackers carry out, often backed by nation-states or organized crime. APTs are hard to detect and can secretly continue stealing information for months before anyone notices.

Phishing

Phishing involves tricking individuals into revealing sensitive information, like passwords or credit card details, by pretending to be a trusted entity or individual. For example, an employee might receive an email that looks like it’s from their boss, asking for sensitive company information, only to find out it was a scam. It’s one of the most common and effective ways for cybercriminals to gain access to company networks.

Insider threats

Insider threats come from current or former employees, contractors, or business partners who misuse their access to company systems. These threats can be intentional, like stealing company data for personal gain, or unintentional, for instance, accidentally sharing sensitive information with the wrong person.

Distributed denial of service (DDoS) attacks

DDoS attacks flood a network with traffic, overwhelming systems and making services unavailable. These attacks often target companies with high online traffic to disrupt their business operations for hours or days.

Third-party risks

Third-party risks involve the potential dangers posed by vendors, contractors, and partners who have access to your company’s network. For example, if a vendor with access to sensitive customer data doesn’t follow proper security protocols, it could lead to data breaches. So if your company’s partners or contractors have access to your company’s network or data, you should make sure they follow strict security protocols.

Cloud security risks

Cloud security risks involve vulnerabilities in cloud services that could lead to data breaches, for example, misconfigured cloud storage settings that leave data accessible publicly, or account hijacking, where attackers gain control of cloud accounts using stolen credentials. It’s a challenge to secure a company’s cloud settings and tightly control access to it, but it’s worth it.

The internet of things (IoT)

The IoT connects everyday devices to the internet, which can open new entry points for cybercriminals. Poorly secured IoT devices can lead to unauthorized access to networks and put sensitive data and systems at risk.

Lack of cybersecurity professionals

The shortage of skilled cybersecurity professionals remains a major challenge for enterprises. With the growing complexity of cyber threats, businesses struggle to find and retain qualified experts to protect their systems and data.

 

Fundamentals of enterprise cybersecurity architecture

The foundation of strong enterprise cybersecurity architecture relies on a few core principles that help businesses maintain a secure and resilient network environment.

  • Continuous monitoring. Ongoing monitoring of systems, networks, and data helps detect potential threats in real time. By constantly assessing for unusual activity, businesses can respond swiftly to security breaches and prevent further damage.
  • Limited access. Restricting access to sensitive data and systems ensures that only authorized personnel can interact with critical information. This principle helps secure data by minimising the risk of unauthorized access and data leaks.
  • Zero trust policy. A zero trust approach assumes that no user or device, inside or outside the organization, is automatically trusted. This means continuous verification and validation of all users, devices, and applications before giving them access.

Key strategies for effective enterprise cybersecurity

Effective enterprise cybersecurity relies on an effective strategy. We’ve compiled some essential practices for you to include into your security strategy. If followed consistently, they can significantly strengthen your organization’s defense against cyber threats:

MFA for all users

Multi-factor authentication adds an extra layer of security by requiring users to verify their identity through multiple means, like a password and a one-time code.

IDS/IPS for threat detection

Intrusion detection and prevention systems (IDS/IPS) monitor network traffic to identify suspicious activity and actively block potential threats before they cause harm.

Data encryption

Data encryption ensures that sensitive information is unreadable to unauthorized users, even if intercepted, by transforming it into a coded format.

Regular security awareness training

Regular security awareness training educates employees about cybersecurity risks, such as phishing attacks, and ensures they handle data in a safe way.

Role-based access for employees

Role-based access ensures that employees only have access to the data and systems necessary for their role, which minimises the risk of unauthorized exposure. This measure also includes extra authentication steps for admins who have higher access privileges.

Security assessment and penetration testing

Security assessments and penetration testing involve simulating attacks on the system to find vulnerabilities before cybercriminals can exploit them. To fully protect your company’s IT infrastructure, companies should consider both internal and external vulnerability scanning because each type can uncover different risks.

Regular software updates

Regular software updates apply the latest security patches to all systems. This reduces the risk of attackers exploiting outdated software.

Effective crisis management

Crisis management involves having a clear, actionable plan for responding to security incidents, ensuring quick recovery and minimizing damage in the event of a breach.

Data backup and post-incident reviews

Regular data backups ensure business continuity if data is lost or encrypted by cybercriminals, while post-incident reviews help identify weaknesses and improve future defenses.

  • Monitoring the external attack surface for vulnerabilities.

These four solutions are widely recognized as foundational to a strong enterprise cybersecurity strategy, and they’ll remain important in the near future.

The future of enterprise cybersecurity

The future of enterprise cybersecurity is predicted to shift towards more integrated and proactive solutions. Businesses are already moving away from traditional, siloed security measures towards unified platforms that combine threat detection, response, and prevention.

Tools like SIEM systems and threat exposure management platforms are evolving to offer real-time analytics. This way, they can provide businesses with a clearer and quicker view of potential vulnerabilities.

Artificial intelligence and machine learning are also playing a role in automating threat detection, making it faster and more accurate. These technologies can analyze vast amounts of data fast and identify patterns that would be hard for humans to spot.

Business mindsets are also evolving. Companies are moving beyond compliance-driven approaches to cybersecurity and are becoming more proactive. Security is increasingly seen as a strategic asset, not just a necessity. More leaders now recognize that a breach can have severe financial and reputational consequences. As part of this shift, businesses are embracing zero trust architecture, which assumes no device or user is trustworthy by default and require continuous verification.

Cyber exposure: Assessment and exposure management

What is cyber exposure, and how can you manage it effectively?

Cyber threats are a significant concern for modern organizations, and it can sometimes feel as if danger lurks around every digital corner. Managing your organization’s total cyber exposure is key to protecting sensitive customer information and preventing devastating data breaches. Let’s take a look at how to assess and manage your cyber exposure so you can keep your systems safe.

What is cyber exposure?

Cyber exposure is a broad term that covers all the risks and vulnerabilities in a digital system. Organizations with high cyber exposure are easy targets for hackers and other threat actors. If left unchecked, it can lead to a system breach or an exposure of sensitive data.

Many risks and vulnerabilities fall under the cyber exposure umbrella and can be broken into two categories: third-party and first-party exposure. Third-party exposure leaves you vulnerable to external threat actors, like hackers and other malicious cybercriminals. First-party exposure leaves you vulnerable to internal security threats, such as accidental data exposure or disgruntled employees.

Understanding your cyber exposures is an essential part of any enterprise cybersecurity strategy. Larger systems create a greater possible attack surface and increase your cyber exposure. You’ll need to constantly monitor and update your systems to keep pace with new threats and eliminate vulnerabilities.

Cyber exposure vs. vulnerabilities vs. cyber risks

The terms “cyber exposure,” “vulnerabilities,” and “cyber risks” are often used when evaluating cybersecurity strategies. Let’s break down what these terms mean in this context.

  • Cyber exposure: Exposure is the overall state of your systems relative to the current threat landscape. The more vulnerabilities and higher risk levels you have, the greater your cyber exposure is.
  • Vulnerabilities: Vulnerabilities are specific weaknesses that could leave your system vulnerable to attack or exposure. For example, poor access management could make it easy for hackers to break in.
  • Cyber risks: Risks are the potential for losses or damage that could result from vulnerabilities. This threat could include data exposure, system damage, or financial losses.

What are the key components of cyber exposure?

Cyber exposure is complex and multifaceted. When assessing your organization’s cyber exposure levels, consider the following key components.

Digital assets at risk

The first component of cyber threat exposure is the digital assets in your system that are vulnerable to cyber threats. These could include:

  • Endpoints — any devices that connect to a network, such as laptops, smartphones, routers, and printers, as well as on-premise servers and other physical hardware.
  • Applications — software programs designed for desktop and mobile devices.
  • Cloud infrastructure — software and hardware necessary to store data remotely in the cloud.
  • Personal data and credentials — sensitive information such as login credentials, financial details, and personally identifiable information (PII) that cybercriminals seek to exploit.

Over the past few decades, many enterprises have migrated their operations entirely online. With this shift, the number of digital assets necessary for normal operation has grown substantially. As organizations add new digital assets to their systems, the attack surface increases, with more possible vulnerabilities to be aware of.

Common vulnerabilities

Many organizations have vulnerabilities in their systems that increase their cyber exposure despite having a cybersecurity strategy in place. Some examples of common cybersecurity vulnerabilities include:

  • Unpatched software. Hackers will exploit flaws in outdated software programs to launch cyberattacks. Installing software patches and updates as soon as they’re available is necessary to maintain security.
  • Misconfigurations. When teams fail to configure the settings properly while installing new hardware or software, it makes the systems vulnerable.
  • Code errors. Even a small mistake in your code could leave your system open to data breaches or attacks, which is why the pre-launch review is essential.
  • Poor access controls. When organizations fail to implement password security or multi-factor authentication requirements, user accounts are vulnerable to compromise.
  • Lack of privilege levels. Another common mistake is giving every user access to the entire system rather than designating privilege levels based on roles and responsibilities. This equal access leaves systems vulnerable to internal threats.
  • Poor encryption. Data should be encrypted in transit and at rest to prevent exposure. However, organizations may fail to encrypt all data or use encryption protocols that aren’t strong enough to hold off external threat actors.
  • Lack of system monitoring. Implementing 24/7 system monitoring and threat detection tools helps teams catch cyber threats as soon as they happen to prevent them from escalating. Failing to monitor systems puts teams on defense in the event of a cyberattack, making them struggle to recover lost data and get systems up and running again.

How does cyber exposure lead to risks?

The greater your cybersecurity exposure, the higher your risk of cyberattacks, data loss, and other adverse events. Threat actors focus on organizations with a high level of cyber exposure and look for vulnerabilities to exploit. Many hackers use new technologies and attack strategies to stay one step ahead of their targets.

More specifically, these threat actors will look for exposed assets they can access without authorization. For example, they might identify a misconfiguration in the company’s software and use that to gain access to secure systems. Then, they’ll select the most effective attack vectors for their goals.

Examples of common attack vectors include:

  • Social engineering. Threat actors use emotional manipulation to trick targets into sharing valuable or sensitive information. The most common example is phishing when a hacker sends a message posing as a trusted organization and exploits this trust to trick their target into sharing secure login credentials or financial information.
  • Malware. Hackers embed malicious software downloads into email attachments or decoy websites, often using infostealer malware to spy on targets. These programs can spy on you or even steal your files.
  • DDoS attacks. Distributed denial-of-service (DDoS) attacks overwhelm target systems with requests and make them unable to function. These attacks are typically conducted using botnets.
  • Man-in-the-middle attacks. Hackers intercept digital communication between two people, often by exploiting other users on public Wi-Fi networks. Cybercriminals use this strategy to steal data or even send false messages.
  • SQL injections. Hackers inject malicious SQL code into web application forms, which allows them to steal or manipulate data.
  • Brute-force attacks. Hackers use trial and error to guess passwords and other login credentials. Bots speed up this process by automatically testing character combinations or already leaked credentials until they find a match.
  • Insider attacks. Employees or business partners target your systems from the inside. These attacks can happen when disgruntled employees partner with outside threat actors or by accident due to negligence.

This level of cyber exposure has real-world consequences. Some of the risks associated with extensive cyber exposure include:

  • Downtime. If cybercriminals exploit active attack vectors, your systems could be offline for an extended period of time.
  • Financial losses. Recovering from a cybersecurity incident is an expensive process. Between lost revenue, system repair costs, and fines, these security incidents can take a dent out of your budget. The average cost of a data breach in 2024 was $4.88 million.
  • Lost or exposed data. When data is exposed, it puts your customers at risk of identity theft. Your intellectual property and other secure business data could also be stolen.
  • Compliance concerns. Depending on your location and industry, data breaches could result in fines or even legal consequences.
  • Damaged reputation. A cybersecurity event can make it difficult for both current and future customers to trust your business. It takes time to recover your reputation and rebuild that trust.

 

How to assess and measure cyber exposure

An honest, thorough assessment is the first step to reducing cyber exposure. Since cyber exposure is a multifaceted concept, you’ll need to review many aspects of your system and make changes accordingly.

Some organizations calculate and track a cyber exposure score, which is a numerical quantification of cybersecurity risks across your entire system. However, there isn’t a standard system for measuring cyber threat exposure, so if you take this approach, you’ll need to develop your own formula. Tracking a cyber exposure score helps organizations monitor security progress and changes over time.

If you’re unsure of your organization’s current cyber exposure levels, use the following strategies to assess them.

Attack surface mapping

Your attack surface is the total number of vulnerabilities or pathways an attacker could use to infiltrate your system. The more exposed assets you have, the larger your attack surface will be.

To better understand your current risk levels, you’ll need to map out your current attack surface. Your attack surface can be divided into three broad categories: digital, physical, and social.

  • Digital attack surface — entry points in your digital systems or network, such as misconfigurations, outdated software, or poor access controls.
  • Physical attack surface — entry points or vulnerabilities in your office or remote workspaces, such as lack of locks, cameras, or access protocols.
  • Social engineering attack surface — entry points or vulnerabilities to phishing and other social engineering attacks. For example, attackers may set up a phishing domain that mimics a legitimate website to trick users into revealing sensitive information. Employees without cybersecurity training or awareness significantly increase this risk.

To map your attack surface, identify which assets are exposed and how they connect to each other. Start by listing all your digital assets and identifying possible vulnerabilities.

  • Endpoints — computers, mobile devices, routers, printers, point-of-sale devices.
  • Digital network assets — firewalls, gateways, domains, IP addresses.
  • Software — operating systems, SaaS platforms, traditional hosted or on-premise platforms.
  • Data storage — on-premise and cloud servers.
  • IoT devices — smart appliances, security systems, industrial sensors, wearables.
  • Teams — employees and contractors who use your systems.

Each of these assets could represent a potential attack vector if they aren’t properly secured. It’s also important to note that a vulnerability in one asset could affect your entire system. For example, if one software platform is out-of-date, it could give a tech-savvy cybercriminal access to your endpoints or even your entire network.

Vulnerability assessment and penetration testing

Once you’ve mapped your attack surface, the next step is conducting a thorough vulnerability assessment. This step will help you identify potential weaknesses that need to be addressed in your future cybersecurity strategy. The process uses automated scanning tools to find system vulnerabilities you might have overlooked in a manual assessment.

To ensure that no weaknesses are overlooked, you’ll need to conduct both internal and external vulnerability scanning. External vulnerability scans pinpoint ways that cybercriminals could get into your systems. Internal scans, on the other hand, focus on the vulnerabilities deeper in your system that cybercriminals could exploit once they get access.

Another essential strategy for measuring your cyber threat exposure is penetration testing. This is the process of simulating a cyberattack to test your system’s defenses and ensure you’re prepared for real-life threats.

Pen tests are typically conducted by third-party ethical hackers. Ideally, these contractors should have minimal prior knowledge of your systems because this test simulates real-life cyberattack conditions.

Ethical hackers will try various strategies throughout the pen testing process, such as social engineering, brute-force attacks, and SQL injections. However, they won’t cause damage once they’ve made it into your systems. Instead, they will document the vulnerabilities they find so you can improve your future cybersecurity strategies.

Threat intelligence and monitoring

External cybersecurity threats are always evolving because cybercriminals develop new strategies. You’ll need to collect threat intelligence and implement ongoing monitoring to stay one step ahead.

To do this, you’ll need to collect data from across your systems. You’ll also need to implement 24/7 system monitoring tools if you haven’t already. This approach will help you identify network activity patterns and vulnerabilities.

Then, compare data from your systems to information about current and emerging threats. One way to do this is by using threat intelligence tools to scan dark web forums for possible threats. Identify which threats are most likely to impact your organization. This information will help you better assess your cyber exposure and adjust your cybersecurity strategy accordingly.

Compliance and regulatory considerations

An often-overlooked part of cyber threat exposure is compliance with cybersecurity frameworks, legal standards, and industry best practices. If you aren’t compliant with these systems, your cyber exposure will be higher than that of an organization that prioritizes compliance.

For example, organizations in the European Union will need to comply with the General Data Protection Regulation (GDPR), a law that standardizes consumer data protection. Additionally, certain sectors must adhere to NIS2 requirements. Many countries in other parts of the world have similar data protection requirements.

Adhering to compliance standards and regulations is necessary to avoid fines and legal action. However, it’s also a necessity to reduce your cyber threat exposure.

How to reduce cyber exposure

Reducing your cyber threat exposure helps you maintain a safe digital environment and protect your organization’s most valuable data. If your current cyber exposure levels are higher than you would like, here’s what you can do to reduce them.

1. Strengthen access and network security

Start by limiting who has access to your networks and systems. Implement stronger password and multi-factor authentication requirements. This step will reduce the chances of a hacker “guessing” employee login details using brute-force attacks.

On top of that, make sure to limit access for employees and contractors based on their responsibilities, rather than giving everyone access to the entire system. When employees or contractors leave, be sure to remove their credentials right away to limit your exposure.

In addition to implementing stronger access controls, monitor your network for suspicious activity. Investing in 24/7 monitoring and intrusion detection will help you identify and neutralize threats as soon as they happen. You should also supplement this with other network security protection tools, such as firewalls, antivirus software, and endpoint detection and response.

2. Protect data and maintain systems

Your systems and data are the backbone of your operations, and if they’re compromised, it can have serious consequences for both your customers and your business. To protect them, start by scheduling regular backups and implementing data loss prevention tools. Your data should always be backed up to a different system than the one you’re using.

You’ll also need to set up a schedule for system maintenance. Use patch management tools to determine when your software programs need to be updated. Additionally, take a full inventory of your digital assets on a regular basis and remove unused services and accounts. This is an easy way to reduce unwanted cyber exposure and keep your systems lean at the same time.

3. Strengthen resilience with policies and training

One component of cyber risk exposure that’s often overlooked is employee training. If your team isn’t up-to-date with cybersecurity best practices, they could accidentally expose data or fall victim to social engineering messages.

Conduct regular training sessions on cybersecurity best practices and implement policies that employees can reference. Additionally, make sure to develop a documented incident response plan and a business continuity plan to help your team spring into action if an attack happens.

4. Manage third-party vendor risks

Working with third-party vendors and contractors is necessary for many businesses but can increase your cyber exposure. Before working with a new third-party service provider, conduct a full cybersecurity assessment to ensure they are safe to work with. You may also want to sign a cybersecurity agreement with vendors before your partnership starts.

How to approach exposure management

Taking a structured approach to cyber threat exposure management is necessary to ensure that no vulnerabilities are overlooked. Evaluating and reducing your cyber exposure should become a routine and repeatable part of your security strategy. Let’s break down how to approach it.

Core principles of cyber exposure management

Cyber exposure management has a few core principles, many of which we’ve already touched on in this article. These include:

  • Digital asset inventory. Take a full count of all digital assets, making adjustments as needed.
  • Attack surface mapping. Build a visualization of your system’s entire attack surface, identifying possible vulnerabilities.
  • Risk prioritization. Identify which risks are most dangerous and decide which vulnerabilities to address first.
  • Mitigation strategies. Take steps to strengthen your security posture and prevent cyberattacks before they happen.
  • Continuous monitoring. Monitor your systems for threats or unusual activity so you can respond right away.

The role of exposure management frameworks

An exposure management framework is a system that helps organizations track and control their cyber threat exposure levels.

Notable exposure management frameworks include Threat and Exposure Management (TEM) and Continuous Threat Exposure Management (CTEM). Both frameworks focus on identifying vulnerabilities and preventing cyberattacks before they happen. However, CTEM focuses on continuous, ongoing processes to keep exposure levels consistently low.

Leverage security automation to prevent cyber exposures

Reducing your cyber threat exposure is a complex process, but security automation tools can make it more efficient. Today, plenty of software programs on the market can help you scan your systems for vulnerabilities and identify areas to improve.

Common types of data breaches and tips on how to prevent them

Types of data breaches and their prevention

A data breach means that attackers have successfully compromised your company’s cyberdefenses and gotten their hands on some corporate data. A serious data breach could ruin your business’ reputation, let alone cost a fortune to recover from. Knowing the common ways that cybercriminals breach data security will help you keep your company’s defenses resilient to attacks.

What is a data breach?

A data breach is any event in which someone accesses confidential information without permission. But what is a data breach in the cybersecurity context? It’s an unauthorized access, theft, or exposure of sensitive digital information, often stored in computer systems, networks, or cloud services.

During the third quarter of 2024 alone, data breaches exposed more than 422 million user accounts worldwide, while the cost of a data breach in 2024 reached a global average of USD 4.88 million.

You might think a data breach always has some malicious intent behind it. However, a data breach can sometimes happen due an accidental data leak or human error.

The most common types of data breaches

A data breach may easily become your company’s most expensive problem. Check out our comprehensive list of the most common types of data breaches and their causes so that you can direct your security effort toward preventing these threats.

Malware

Malware is any harmful software (program or file) that cybercriminals develop to steal data, cause damage to computers and systems, or deprive legitimate users of their access to the system or information. The number of malware attacks globally has been rising steadily since 2021, with 6.06 billion cases reported in 2023.

Though numerous types of malware can bring about a data breach, they spread in similar ways. Typically, you may catch a malware infection when you do the following:

  • Download an infected file or app.
  • Click on a malicious link or ad.
  • Install software from unreliable sources.
  • Use legitimate software that has vulnerabilities that attackers may exploit. This includes postponing software updates designed to patch up security flaws.
  • Fall for a phishing attack or scam.

Let’s explore the most common and damaging types of malware.

Ransomware

Ransomware encrypts or locks data on your device and demands a ransom for the decryption key, effectively locking you out of your own system. In businesses, a ransomware infection can escalate into a corporate data breach if attackers steal sensitive information before encrypting it, threatening to expose or sell the data if you don’t pay up.

Spyware

Once spyware infects your device, it gathers information you store on it, including personal and corporate data, and sends it to the attackers. Typically operating in the background, spyware can track your browsing habits, capture keystrokes, and monitor online activities without your knowledge.

Viruses

Viruses are malicious software programs that attach themselves to legitimate files or applications, spreading and causing harm either when you execute the malicious file or executing automatically by exploiting operating system or software vulnerabilities.

Worms

Worms are self-replicating malware that spreads independently without needing a host file or program, often exploiting network vulnerabilities to infect other systems automatically.

Adware

Adware is a type of software that delivers intrusive advertisements to users. Typically, it collects data or redirects users to specific websites, often malicious.

Trojan horses

Trojan horses are a particularly sneaky type of malware that downloads onto your computer disguised as legitimate software. They are capable of stealing data and installing additional malware.

Rootkits

A rootkit is a collection of malicious software that hackers hide on your computer to reach areas otherwise inaccessible to them and to take control of your system. Rootkits operate at a deep system level, often hiding within core operating system files, making them invisible to standard security tools and able to bypass typical removal methods.

Keyloggers

Keyloggers are malicious software or hardware that secretly keep track and record your every keystroke. This way, they can capture sensitive data like passwords, messages, and credit card details.

Social engineering

Social engineering is the psychological manipulation of people to make them compromise data security. Criminals often create fake emails, ads, or websites designed to look legitimate, tricking you into revealing personal information, clicking a malicious link, or downloading harmful attachments, which may all result in a corporate data breach.

Phishing attacks

Phishing attacks are one of the most common social engineering methods that come in different forms:

  • Spear phishing. In spear phishing, attackers use personalized information to target a specific person, group, or organization. They aim to coerce you into sharing sensitive information, downloading malware, or sending them money.
  • Email spoofing. Cybercriminals send fake emails that appear to come from a trusted source to trick you into revealing sensitive information.
  • Whaling attacks direct their effort towards high-profile companies and individuals, such as executives, to gain access to confidential corporate or client data.

SQL injection

In SQL injection, attackers inject malicious SQL code into an entry field on a website or application, tricking the database into revealing unauthorized information. This way, they are able to access, modify, or delete data, potentially compromising the security and privacy of the entire database.

Password attacks

A password attack is just what it sounds like — a hacker’s attempt to steal your password by using one or several methods described below.

Credential stuffing

Credential stuffing is the use of automated tools to try stolen username and password combinations from previous data breaches in website login forms with the goal of gaining unauthorized access to user accounts.

Password cracking

Password cracking is about trying to access a password-protected system by systematically guessing or decrypting passwords. To crack a password, attackers may use methods like brute force, dictionary attacks, or rainbow tables.

Brute-force attacks

In a brute-force attack, cybercriminals attempt all possible combinations of characters until they successfully guess the correct password. It’s an effective yet time-consuming password-cracking method.

Rainbow table attacks

Rainbow table attacks use precomputed tables of hashed password values to quickly match and reveal plaintext passwords, significantly reducing the time needed to crack them. By comparing stored password hashes against these tables, attackers can bypass the need for repetitive hashing attempts. This method is especially effective against weak or commonly used passwords.

Insider threats

Insider threats are risks posed by individuals within an organization who, intentionally or not, compromise sensitive information, security, or operations.

Data leakage

Data leakage is an exposure of confidential or protected data. An individual within an organization could intentionally or unintentionally share sensitive information with unauthorized individuals or through unsecured channels. Apart from human error, data may also leak due to software vulnerabilities or poor data security measures.

Data exfiltration

Data exfiltration is deliberate, unauthorized transfer of data from within an organization to an external destination or third party.

Advanced threats

Advanced threats are sophisticated, targeted cyberattacks designed to evade traditional security defenses and infiltrate networks undetected. These threats often employ stealthy techniques, persistence, and customized malware.

Cyber espionage

Cyber espionage is a form of digital spying. It involves the use of cyber tactics to covertly gather confidential information from governments, corporations, or individuals, often for strategic or competitive advantage. Nation-states, state-sponsored groups, and highly skilled threat actors opt for cyber espionage to target intellectual property or classified information.

Advanced persistent threats (APTs)

Advanced persistent threats are targeted, covert cyberattacks in which intruders gain unauthorized access to a network and remain undetected over an extended period. Typically, nation-states and organized crime groups conduct these highly sophisticated attacks.

Zero-day exploits

In zero-day exploits, attackers take advantage of unknown security vulnerability in computer software, hardware, or firmware. The software vendor and security community don’t yet know about these vulnerabilities, leaving no time (“zero days”) for developers to patch them, which, in turn, allows attackers to infiltrate systems before defenses can be implemented.

Supply chain attacks

In supply chain attacks, cybercriminals infiltrate an organization by compromising its external partners or third-party vendors that have access to the organization’s systems or data. For example, by targeting trusted suppliers, attackers can introduce malicious code or vulnerabilities to a target’s system or network.

 

Network and session attacks

Network and session attacks target active network connections and communication sessions to intercept, alter, or hijack data.

Man-in-the-middle attacks

A man-in-the-middle attack happens when a cybercriminal secretly intercepts and potentially alters the communication between two parties who think they’re communicating directly, or between a user and an application. It’s like someone eavesdropping on a private conversation, possibly even changing the information before it reaches the other person.

Session hijacking

Session hijacking involves taking over an active internet session between a user and a web application. This allows the attacker to act as the legitimate user and, as a result, gain unauthorized access to sensitive information and actions within the session.

ARP spoofing

ARP spoofing is a technique where an attacker sends falsified (spoofed) address resolution protocol (ARP) messages onto a local area network to link their device’s MAC address with the IP address of a legitimate host. This allows the attacker to intercept, modify, or stop data intended for that IP address.

DNS attacks

DNS attacks exploit vulnerabilities in the domain name system (DNS) to compromise the availability, stability, or integrity of DNS service. By disrupting or manipulating DNS, attackers can redirect users to malicious websites, intercept sensitive data, inject malware, or enable further attacks. Common types include DNS spoofing, DNS amplification attacks, DNS tunneling, and pharming.

  • DNS spoofing is an attack where malicious actors manipulate DNS records or responses to redirect users to malicious websites without their knowledge.
  • A DNS amplification attack is a type of distributed denial-of-service (DDoS) attack that exploits vulnerable DNS servers by sending small, spoofed requests that elicit large responses. These amplified responses overwhelm the target server with massive amounts of data, causing network disruption or service outages.
  • DNS tunneling routes DNS requests to an attacker’s server, creating a covert channel for command-and-control communication and data exfiltration, often blending with legitimate traffic to evade detection.
  • Pharming redirects users from legitimate websites to fraudulent ones by altering DNS settings, poisoning DNS caches, or exploiting vulnerabilities. Once on a fake site, unsuspecting users often enter sensitive information, believing they’re using a legitimate service.

Botnets

Botnets are networks of internet-connected devices infected with malware and controlled by attackers without the owners’ knowledge. Hackers use various tactics to compromise devices, turning them into “bots” to perform coordinated malicious activities like launching DDoS attacks, distributing malware, spamming, or stealing sensitive data.

Rogue access points

Rogue access points are unauthorized wireless access points installed on a secure network without explicit authorization from the network administrator, either by a well-meaning employee or a malicious attacker. These physical devices, typically wireless routers or similar hardware, create unauthorized wireless entry points into the network or establish unauthorized Wi-Fi networks that may bring about a data breach.

Wi-Fi eavesdropping

Wi-Fi eavesdropping is a cyberattack where criminals intercept unencrypted data transmitted over wireless networks. They do so to intercept sensitive data such as login credentials, financial details, or private communications, especially on unsecured or public Wi-Fi networks.

Physical and device-based threats

Malicious actors don’t always target the software — they often aim to compromise devices themselves to access sensitive data stored within.

SIM swapping

SIM swapping is a type of account takeover fraud where attackers trick or bribe mobile carriers into transferring your phone number to a SIM card under their control. This way they can bypass two-factor authentication, intercept calls and texts, and gain access to sensitive accounts or personal information.

Mobile device breaches

Attackers may exploit software vulnerabilities in mobile devices to access them remotely by leveraging weaknesses in operating systems, apps, or third-party software. Poor device security, such as failing to enable multi-factor authentication, significantly helps attackers by making it easier to bypass authentication mechanisms and maintain unauthorized access.

Physical theft

Malicious actors may steal laptops, smartphones, and other portable devices that they later break into, which can result in a data breach.

Tailgating

Tailgating is simply following after an authorized employee into restricted areas without proper verification.

Shoulder surfing

Shoulder surfing is a technique where an attacker observes someone’s screen or keyboard from a close distance to steal sensitive information, like passwords or PINs. They typically do so in public places, such as cafes or airports. You should always take care to protect your screen from prying eyes.

Dumpster diving

Dumpster diving simply means going through someone’s trash in hopes of finding discarded documents or items that contain valuable information, such as bank statements or personal details.

Web application attacks

Another way for attackers to get access to an organization’s IT ecosystem is to try exploiting the vulnerabilities and weaknesses in web applications.

Cross-site scripting (XSS)

Hackers sometimes inject malicious scripts into trusted websites — this is called cross-site scripting (XSS). By using XSS, attackers are able to execute the script in their victim’s browser and steal cookies, session tokens, or sensitive data from their victim’s computer.

Cross-site request forgery (CSRF)

In cross-site request forgery, an attacker tricks you into executing unauthorized actions on a website where you are authenticated, often through a malicious link or script. This allows attackers to change account settings, transfer funds, or carry out other unintended operations without your knowledge.

Formjacking

Formjacking occurs when cybercriminals inject malicious JavaScript code into a website, taking over the functionality of its form pages to collect sensitive user information. Attackers intercept data such as credit card details entered by users in real time, often without the website or its visitors realizing the breach.

Drive-by downloads

A drive-by download is an unintentional download of malicious code to your computer. These downloads can happen when you visit compromised or malicious websites. Attackers exploit vulnerabilities in browsers, plugins, or operating systems to install malware, which can steal data or create backdoors for future attacks.

Exploit kits

Exploit kits are toolkits that attackers use to scan for and exploit vulnerabilities in software or systems so they can distribute malware or ransomware. These kits automate the process of identifying weaknesses, making it easier for cybercriminals to launch large-scale attacks against unpatched or outdated systems.

Buffer overflow attacks

In a buffer overflow attack, cybercriminals exploit buffer overflow, a software coding error, by sending more data to a memory buffer than it can handle, which causes excess data to overwrite adjacent memory. This allows attackers to execute malicious code, steal data, and gain unauthorized access to corporate systems.

Preventative measures and best practices

The onslaught of ways that attackers may breach your organization’s data security may seem overwhelming. However, a steady and proactive approach to security practices can strengthen your defenses against potential data breaches.

Network security

To take your corporate network security — and data protection — to the next level, you should implement a multi-layered approach that includes the use of firewalls, IDS, VPNs, and threat management solutions.

Firewalls create a barrier between trusted internal networks and untrusted external networks, blocking unauthorized traffic and filtering malicious data. If someone manages to bypass the firewalls, an IDS (intrusion detection system) can detect unusual activity and provide real-time alerts, enabling you to mitigate the threat promptly.

A VPN (virtual private network) secures data in transit, ensuring that remote workers and branch offices connect to the corporate network through encrypted channels to prevent eavesdropping and unauthorized access.

To top off your network security effort, start using a threat exposure management platform like NordStellar. It’s an advanced solution that automatically cross-references credentials found on the deep and dark web with your employee, customer, and partner accounts. If NordStellar’s Data Breach Monitoring solution finds any leaked credentials, it notifies you instantly, giving you the chance to take action to secure your accounts and resources.

Encryption

To protect sensitive corporate information, you should prioritize encryption by adopting data encryption in transit and at rest, as well as SSL/TLS protocols.

We advise encrypting your stored data on servers, databases, and devices to prevent a potential security breach, even if someone steals or compromises your data. You should also use encryption to secure data in transit between systems to prevent attackers from intercepting it during transmission over the internet or private networks.

Make sure to implement SSL/TLS protocols to secure web communications. This will create encrypted connections between users and websites and protect sensitive information like login credentials and payment details from potential breaches.

Access controls

Curbing data breaches also involves controlling who can access sensitive information and systems. Role-based access control is an effective approach that allows you to assign permissions based on an employee’s job responsibilities. It’s safest to only let individuals have access to the tools and data necessary for their role.

Equally important is the principle of least privilege, which means granting users the minimum level of access required to perform their tasks. By restricting permissions to only what’s essential, you can significantly reduce the attack surface, making it harder for cybercriminals to exploit compromised data.

Data minimization

It’s recommended to practice data minimization in any business. By collecting only the information necessary for your business operations, you avoid excess data — unnecessary or redundant information stored in your systems — that could become an attractive target for hackers.

A lean and secure data management system also includes regular purging of outdated or redundant data to reduce storage demands and limit the impact of a potential security breach.

Physical security

Ensure physical infrastructure is secure by securing server rooms with controlled access measures like keycards or biometric locks. Complement this with surveillance systems to monitor critical areas. A surveillance system may deter intrusions and provide evidence in case of a security breach.

Regular software updates

Protect your systems by regularly updating software, operating systems, and applications to patch vulnerabilities that attackers could exploit. Enable automatic updates where possible to ensure your systems always run the latest, most secure versions.

Strong password policies

Enforce strong password policies by requiring your employees to use complex, unique passwords and regular updates to protect against identity theft and security breaches. Encourage your employees to use password managers to securely store and manage their credentials.

Implementing multi-factor authentication

Multi-factor authentication (MFA) adds an extra layer of security and protection against identity theft because users must verify their identity through multiple methods before they can gain access to their accounts or company resources. MFA makes it harder for attackers to exploit compromised passwords alone.

Data backup and recovery plans

Make sure you regularly back up your data and have a set recovery plan if a data breach occurs. Storing your critical information securely is especially important in case of a cyberattack, hardware failure, or system disruption.

Regular security audits

Conduct regular security audits to identify vulnerabilities, assess the effectiveness of your cybersecurity measures, and ensure compliance with industry standards. These audits will help you stay proactive in addressing potential threats before they become serious issues.

Employee training and awareness

The more your employees know about data breaches and security practices, the better you are equipped to both protect your business from security breaches and respond to them in a timely manner. Regular employee training is a must to avoid data breaches due to human error.

What is a data breach, and how does it happen?

What is a data breach, and how does it happen?

Data breaches are one of the most common cybersecurity threats that businesses and individuals have to face. What may seem like a small data leak can result in huge financial loss and reputational damage. So, what is a data breach, how does it happen, and how can you safeguard your data?

What is a data breach?

A data breach occurs when unauthorized people gain access to personal, classified, or otherwise protected information. Data breaches can be unintentional (for example, resulting from a company file sent to the wrong person) or malicious (caused by phishing emails, hacker attacks, or malware infections).

More often than not, businesses and individuals suffer malicious data breaches. Since data can hold significant value, it’s natural that cybercriminals try to steal it and make a profit from it either by selling the obtained information on the dark web or ransoming it for huge sums.

How do data breaches happen?

Typical data breaches involve specific steps, such as reconnaissance, gaining access, extracting data, and covering the hackers’ tracks. In certain cases, cybercriminals can also use privilege escalation or lateral movement.

Here’s how malicious actors breach systems to steal data:

  • Step 1 – Reconnaissance. Before launching an attack (be it phishing, malware, session hijacking, or brute force attacks), cybercriminals will scout the system for potential attack vectors and system vulnerabilities. Once they gather the information they need, the cyberattack is ready to go.
  • Step 2 – Gaining access. This one is also known as the initial compromise. During this process, hackers use their preferred attack method to gain unauthorized access to the system and its data.
  • Step 3 – Privilege escalation. Once they breach the system, malicious hackers may need higher clearance, such as admin rights, to bypass restrictions and access more sensitive data. To do so, hackers exploit system vulnerabilities until they get admin-level access, which strengthens their control over the compromised system.
  • Step 4 – Lateral movement. When hackers gain enough power over the system’s controls, they can use them to move laterally across the network. That means malicious actors have open access to all or most system files, most significantly those that include sensitive information.
  • Step 5 – Data exfiltration. Once the bad guys are completely set in the breached system, they begin exfiltrating the “good stuff.” Using extraction tools, hackers steal personal information, business secrets, and classified documents in seconds, sometimes before system owners can even notice anything.
  • Step 6 – Covering tracks. After completing their task, the hackers will try to cover up any trace of their presence. This usually means deleting activity logs or disabling security systems so that the system owners and security do not pick up any leftovers, unusual files, or suspicious activities.

The steps above describe a perfect data breach, during which the system operators are unaware of being attacked. Depending on the type of attack, the system security, or the vigilance of its owners, data breaches can be spotted early or even during the attack, forcing malicious actors to adjust their methods.

What are the main causes of data breaches?

Poor cybersecurity practices, such as weak passwords or unpatched vulnerabilities, are usually the main causes of data breaches. Cybersecurity experts also note that human error is among the most common causes of this issue and add misconfigured systems and physical credential theft (or loss) to the list of contributing factors.

Hackers target both small and large businesses for two different reasons. Small businesses often lack robust cybersecurity practices, making them easy targets. Meanwhile, large companies often present a challenge that can motivate hackers to breach the system and humiliate the company publicly, resulting in financial and reputational damage. Some hackers may also breach systems to commit espionage or even shine a light on a specific political or social cause (a process also known as hacktivism).

Based on these simple principles, malicious actors can exploit different vulnerabilities. For example, small businesses often suffer phishing and other social engineering attacks. Big businesses aren’t immune to phishing either, due to the larger number of employees and extensive communication channels. However, they’re also more likely to experience brute force attacks, which can breach the company’s cybersecurity and result in data theft.

Businesses may also face different types of data breaches caused by insider threats (employees who willingly help hackers get inside), malware, unpatched system vulnerabilities, or even lost or stolen company devices. This is why companies invest in cybersecurity measures, such as password managers, two-factor authorization (2FA), and skilled cybersecurity personnel. However, it’s equally important to train all employees to help them understand their role in maintaining cybersecurity in the workplace.

What methods are used in data breaches?

As mentioned, hackers can use numerous methods to breach the systems and steal data. From malware to third-party software, here are the main ways in which malicious actors may launch a data breach attack:

Malware

Hackers use malware to slip into the system undetected. Files with spyware or ransomware, trojans, and infostealers are among the most common types of malware that can open doors for hackers to access your system, potentially gain admin-level privileges, and steal sensitive data.

Malware can infect your system through various methods, including phishing links, infected USBs, and unsafe websites. Therefore, employee vigilance is essential in preventing this type of cyberthreat.

Social engineering

Social engineering refers to attacks that involve direct contact between the hacker and the system user. Malicious actors create believable scenarios and try to lure users into providing sensitive information, using methods such as phishing.

Whaling is another great example of a social engineering attack. This method is used to target big companies and works similarly to phishing. During whaling attacks, hackers send emails to high-level employees (executives, CEOs, and CFOs), pretending to be representatives of reputable companies, such as law firms. In those emails, the hackers may urge their victims to wire money, share the company’s secrets, click on suspicious links, or download unknown files.

Phishing

Phishing is a social engineering cyberattack that exploits users by baiting them to click on links or files that contain viruses, spyware, and other malware. Hackers usually attempt phishing through email and contact employees with messages that create a sense of fear or urgency and encourage quick response. For example, phishers may target employees by pretending to be representatives of legitimate organizations, and prompting the users to take immediate action based on the content of the email.

If an employee takes the bait, they may click on the link which typically hosts some kind of malware, potentially opening the doors for cybercriminals to breach the system. The landing pages of some phishing links may also replicate known user interfaces, such as system login windows, and scan everything the user types (including username and password), further exposing the system to the threat.

Human error

No matter how hard people try, sometimes accidents happen. A lost keycard, a typo in the email address field, or a lost work laptop can cause a data breach if they fall into the hands of malicious actors. If something like that happens, it’s important to report the issue without ignoring it and be vigilant of potential breaches or attacks. Offering support to the person who made a mistake is also a good practice for maintaining loyalty among employees.

Insider threats

In some cases, hackers can initiate a data breach with assistance from someone inside the organization. According to the experts, this issue has become so prevalent that it now ranks among the top cybersecurity risks for large businesses. To prevent insider threats, you can limit access to sensitive information or invest in a better workplace environment (people are less likely to turn against the company when they actually like working there, right?).

Supply chain attacks

Supply chain attacks occur when hackers target part of a company’s supply chain software. In simple terms, it’s a type of cyberattack that targets service providers, vendors, and third-party apps on which the company relies. Some businesses may need to share access rights or sensitive information when using third-party services. Therefore, a successful supply chain attack can expose your company’s system even if it wasn’t attacked directly.

Unpatched vulnerabilities

As soon as companies develop new strategies to safeguard their data, malicious actors come up with new ways to overcome them. System security gets obsolete fast, exposing businesses to cyberattacks. Overdue updates and unpatched vulnerabilities invite hackers to breach your networks and steal sensitive data. To avoid such problems, companies should install system updates as soon as they launch while constantly monitoring and patching additional system vulnerabilities.

Weak or stolen credentials

Weak passwords are one of the most common causes of data breaches. Far too often, people believe their passwords are strong enough, while a hacker with a capable toolset can crack them in mere seconds. Safeguarding against this vulnerability requires businesses to introduce 2FA and educate employees on password security. Using additional tools such as password managers can also be a huge benefit.

Cloud misconfigurations

While cloud storage is a convenient choice for data storage, poorly configured cloud servers can turn that comfort into a headache in just a few seconds. Insufficient user restrictions, lack of encryption, or disabled logging and monitoring can allow malicious actors to jump into your cloud server and peek at all the sensitive data you might be hiding there.

Third-party access

Third-party access vulnerabilities can allow cybercriminals to steal your business data even without directly attacking your company. Hackers may target a third-party service provider to hijack communications, gain access to specific files shared between your company and the third-party service provider, or learn about potential vulnerabilities.

Safeguarding against this risk is difficult but not impossible. Before entrusting your company’s data to a third-party service provider, make sure that the provider has an impeccable cybersecurity record. Even then, set up separate accounts for communication and use proper information segmentation. In addition, look for ways to safeguard your system in case of a third-party attack.

What are the targets of data breaches?

Data breaches, as the name suggests, mainly target data. Depending on the service the business provides, we can divide that data into more specific types.

  • Personal data. Includes names, surnames, addresses, phone numbers, Social Security numbers, and birth dates. Malicious actors may use stolen personal data to commit identity theft or sell it on the dark web.
  • Financial data. This data type includes credit card numbers, bank account details, and payment information. With this data, hackers can try to carry out fraudulent transactions or drain bank accounts.
  • Login credentials. If the system collects usernames, passwords, or answers to security questions, the data breach will expose them to malicious actors. Needless to say, login credential leaks can pose a huge risk of identity theft and loss of account access (for example, when hackers use the victim’s login details to change the account’s password).
  • Intellectual property. Patents, trade secrets, and research data can harm businesses and cause significant financial damage when in the hands of hackers. Malicious actors may demand ransom for stolen data or try to sell it on the dark web, making a company’s hard work go to waste.
  • Customer and client data. Businesses often collect various types of customer data including, but not limited to, personal and financial information. Suffering a data breach that leaks client data is a huge financial, reputational, and potentially legal blow. Customer data is often the most sought-after target for malicious actors because it causes the most damage, hurting the business and creating thousands of potential new victims.
  • Government data. Some companies may work closely with the government as service contractors. That could mean exchanging sensitive information such as strategic documents, personal data of government employees, or even classified information. Exposing such data to hackers could, at the very least, cause a scandal, let alone destroy careers, or even worse — put someone’s life in danger.

 

What are the consequences of data breaches?

The consequences of data breaches vary depending on the type and amount of stolen data, the size and reputation of the company, and sometimes even the hacker’s “goodwill.” Based on these (and many more) factors, the consequences of a data breach can range from small financial losses to massive reputational damage, compliance regulation breaches, lawsuits, loss of certificates, and even official government hearings.

Typically, after stealing sensitive data, malicious hackers can either use it to further their scams (for example, using stolen client data to launch phishing attacks and steal identities), sell the data on the dark web, or contact the owners of the breached system to demand ransom for the stolen data. If the company has a strong presence in the market or is one of its leaders, the hackers may leak the data for free to cause reputational (and, therefore, financial) damage.

Real-life examples of data breaches

Examples of real-life data breaches prove that even well-known companies, such as Equifax and Yahoo, cannot feel safe from potential cyberattacks. Here are a few high-profile data breach cases:

  • MGM resorts data breach (2023). In early 2023, MGM Resorts suffered a major data breach after a cyberattack that appeared to target its internal systems, causing severe disruptions. A result of a ransomware attack, the breach granted hackers access to sensitive information, including guest data and internal systems. The breach resulted in complete system shutdown along with reputational damage and significant financial loss.
  • Snowflake data breach (2023). Snowflake, a business cloud data platform, suffered a data breach when hackers found a possible entry point through a third-party provider. The supply-chain attack exposed sensitive data stored on Snowflake’s platform, including financial information and business intelligence. This caused a series of security incidents including breaches at other Snowflake-associated companies (such as AT&T and Santander Bank). While the company took swift action and worked with security experts to address vulnerabilities, the snowball of breaches that rolled over Snowflake’s customers resulted in a significant reputational damage.
  • MOVEit Transfer data breach (2023). Progress Software’s MOVEit Transfer, a secure file transfer software, was exploited by a zero-day vulnerability, just last year. The breach affected thousands of organizations worldwide, with hackers gaining access to personal, financial, and healthcare information. The company sustained increased scrutiny and hefty financial consequences.

How can businesses prevent data breaches?

For businesses, data breach prevention requires substantial financial and human resources. Here are some tips on how to safeguard your business against data breaches:

  • Implement two-factor authentication. Safeguarding systems with 2FA provides an additional layer of security and helps detect suspicious or unauthorized access requests more quickly.
  • Encrypt sensitive data. Investing resources in strong encryption can improve your business cybersecurity and increase the safety of sensitive information. While you can use file encryption tools, a VPN such as NordVPN can offer additional benefits (for example, Threat Protection Pro™ features).
  • Build a strong cybersecurity team. Large companies should invest in seasoned cybersecurity specialists. They will help you better prepare for potential cyber threats and strengthen the overall safety of the company’s sensitive data (for example, through educating your employees).
  • Update and patch software regularly. System updates often include new security patches, so it’s crucial to install them as soon as possible to keep your systems up to date.
  • Carry out security audits and employee training. As the old saying goes, “practice makes perfect.” Run regular security audits and employee training sessions to strengthen the company’s cybersecurity and ability to respond to a potential data breach.
  • Create backups and data recovery plans. Data diversification can be a smart strategy. Make sure to create backups for sensitive information and draw up strategies to recover lost data. While this may not protect against a potential data breach, it’ll help mitigate the damage (for example, by avoiding paying a ransom) after a potential cyberattack.
  • Use NordStellar. From the minds behind NordVPN, the latest addition to the Nord family, NordStellar helps businesses identify potential exposures and compromised customer or employee credentials before hackers can take action. It’s a useful tool that aids businesses in data breach monitoring, identifying potential risks, and tracking mentions of your company in cybercrime communities.

What to do if your business suffers a data breach

If the business has suffered a data breach, it’s critical to act fast. First, contain the breach by isolating all affected systems and assessing the damage and the compromised data. Then, start patching vulnerabilities, fixing security gaps, and notifying affected customers and stakeholders. Some laws may also require reporting the data breach to law enforcement (for example, under the GDPR, organizations have 72 hours to report a breach to the relevant data protection authority).

Finally, continue to monitor your systems and review the security policies. The backlash and repercussions may continue for some time. However, while going through the process, it’s important to start upgrading and patching your cybersecurity weaknesses to avoid future cyberattacks.

 

FAQ

What is the average cost of a data breach?

While it’s hard to define a specific figure, the average cost of a data breach usually involves millions of dollars. Some experts indicate that the average cost per lost or stolen record containing sensitive information could be approximately $165, while healthcare records may reach $429 per record. According to IBM’s 2023 Cost of a Data Breach report, the average data breach exposes about 25,000 records. Based on these numbers an average data breach can cost from $4 million to $10 million and more.

How to detect a data breach?

To detect a data breach, check your system activity logs and file directories for suspicious activity. Data breaches usually include connections from unknown devices, changes in file locations or sizes, and unusual data transfers. So if you notice any unauthorized or dubious changes in your system, start investigating. Additionally, use automated security tools, such as NordStellar, and regularly conduct security audits to enhance threat detection capabilities.

How should business report a data breach?

Reporting a data breach may look different depending on where the business operates. For example, in the EU, you must report a breach to your local data protection authority (DPA) within 72 hours of its discovery. In the US, however, most states obligate businesses to notify their Attorney General’s office or consumer protection agencies of any breaches. The requirements vary by state, and the timelines may be shorter than those mandated by federal law.

It’s also critical to inform the company’s customers by sending emails or text messages describing the situation and the steps that will be followed to mitigate the damage.

NordStellar’s attack surface management: Spot vulnerabilities before attackers do

Attack surface management reduces cyber risks

Summary: NordStellar’s attack surface management (ASM) feature provides continuous visibility and assessment of your organization’s external attack surface.

We’re excited to introduce NordStellar’s latest feature – attack surface management (ASM) – designed to provide continuous visibility and assessment of your organization’s external attack surface.

“By introducing ASM, we aim to help improve our clients’ overall security posture, ensuring that their security teams are equipped with insights needed to effectively manage their attack surface, minimize exposure to external threats, and meet regulatory requirements for vulnerability assessments,” says Vakaris Noreika, head of product at NordStellar.

ASM helps security teams monitor internet-facing assets, such as websites, servers, applications, and cloud resources, while identifying and mitigating vulnerabilities before they can be exploited. By automating the discovery of security gaps, NordStellar’s ASM empowers organizations to proactively reduce cyber risks and strengthen their security posture.

Attack surface management feature

Why companies have trouble managing their attack surface

Many companies lack full visibility into their external-facing assets, making it difficult to detect potential vulnerabilities that could be easily found by attackers on the dark web and exploited.

“Any security gaps in a company’s websites, servers, applications, cloud resources, or internet of things devices are a ticking time bomb, and it’s vital to identify and mitigate these vulnerabilities before attackers have a chance to act,” says Noreika.

However, many organizations still struggle with understanding and managing their attack surface due to several key challenges:

  • Unidentified and unmanaged assets. Many organizations struggle to maintain a complete and accurate inventory of their internet-facing assets. Without visibility, securing unknown or forgotten systems becomes impossible, leaving critical blind spots for attackers to exploit.
  • Inefficient manual processes. Traditional methods of asset discovery and vulnerability assessment often involve manual processes, spreadsheets, and disparate tools. This is time-consuming and labor-intensive.
  • Difficulty prioritizing remediation efforts. With limited resources, knowing which vulnerabilities pose the greatest risk and require immediate attention can be a challenge.
  • Lack of real-time threat detection. The attack surface is constantly changing, with new vulnerabilities being discovered and exploited daily.
  • Shadow IT and unknown risks. Unauthorized devices, applications, or services connected to the network without IT’s knowledge (shadow IT) significantly expand the attack surface and introduce uncontrolled risks.

 

How NordStellar’s ASM works

NordStellar’s ASM consists of two main modules – automatic asset discovery and external vulnerability management. Automatic asset discovery maps your infrastructure by running various domain enumeration processes. This way, ASM automatically identifies and catalogs all internet-exposed assets related to your organization, such as web servers, applications, and other network-connected devices. NordStellar can also discover domains, SSL certificates, and IPs.

In the meantime, external vulnerability management continuously monitors and scans the discovered assets for known weaknesses, delivering actionable intelligence to streamline recovery efforts.

How NordStellar’s ASM works

How security teams can put ASM into practice

Continuously monitoring and assessing the attack surfaces is by no means an easy task, requiring a great deal of time and human resources. NordStellar’s ASM provides value for different members of your security team:

  • Security analysts. Imagine starting your day by opening the ASM dashboard, where critical internet-facing vulnerabilities – whether it’s a misconfigured server or an exposed cloud resource – are already detected. You can dive straight into investigating the highest risks, collaborating with IT teams, and implementing fixes before attackers can exploit them.
  • Security engineers. Picture integrating ASM into your workflow. The platform continuously scans your external assets, uncovering weak points that could be exploited. With ASM’s automated discovery, you streamline your vulnerability patching process and address gaps while freeing up time to focus on strategic infrastructure security questions.
  • Security managers. See yourself walking into a stakeholder meeting with NordStellar’s ASM reports. You can clearly demonstrate how the team has reduced the organization’s attack surface, track remediation progress in real time, and provide data-backed proof of compliance. You’re ready to show the tangible value of proactive risk reduction to the entire business.

With ASM, every member of your security team gains the tools they need to strengthen your organization’s security. From real-time monitoring to automated insights and clear reporting, ASM helps you stay ahead of threats and focus on what matters most – keeping your business protected.

Key benefits of NordStellar’s ASM

Security teams are under constant pressure to manage the attack surface: unknown assets, evolving vulnerabilities, and manual processes hamper them down and create unnecessary risk. That’s where NordStellar’s ASM comes in, providing:

  • Minimized attack surface. By identifying and mitigating vulnerabilities, NordStellar’s ASM helps you reduce the chance of a successful attack.
  • Enhanced shadow IT visibility. With ASM, you’ll be able to maintain an accurate list of internet-exposed assets, protecting them from unknown threats.
  • Automation-driven operational efficiency. This lets you avoid manual vulnerability scanning, which is time-consuming and prone to errors.
  • Real-time threat detection. Unlike traditional periodic scans that leave gaps between assessments, ASM ensures continuous monitoring and alerting.
  • Mitigating vulnerabilities before attackers do. NordStellar’s ASM lets you protect your assets before threat actors can do damage.
  • Meeting compliance requirements. You can use ASM to demonstrate compliance with industry regulations that require regular vulnerability assessments.
  • Cost saving. With this feature, you can minimize the financial impact of security incidents.

What is threat exposure, and how can you mitigate it?

What is threat exposure, and how can you mitigate it?

Threat exposure is a metric that every business owner should be aware of. Some might even say that it’s the most important part of maintaining business success. With that in mind, let’s explore threat exposure — specifically, what it is, what it shows, and how companies can reduce it.

Threat exposure: What is it?

Threat exposure is the combined total of cybersecurity risks and vulnerabilities that threaten the company. It encompasses the weaknesses of every part of an organization’s IT environment, starting with the system and finishing with the third-party providers.

The importance of understanding threat exposure

Understanding a company’s threat exposure can provide insight into its security posture. Large threat exposure makes organizations vulnerable to cyberattacks and can lead to significant legal troubles along with major reputational and financial damage. Identifying vulnerabilities and implementing external attack surface management can help businesses curb the biggest cybersecurity weaknesses and reduce the chances of a successful cyberattack.

“Data is the new gold” — once just a catchy Salesforce campaign slogan, now strikes true more than ever. Protecting personal, company, and client information should be a top online priority for any business. Researching and defining effective threat exposure management strategies are the first steps in doing just that.

The dangers of ignoring threat exposure

Ignoring threat exposure in the organization is the same as ignoring the first symptoms of a disease. Eventually, both will cause serious problems. While you may not lose your life, disregarding a company’s threat exposure management can result in data breaches, brute-force attacks, and other cybersecurity incidents. Consequently, these can lead to lawsuits, fines, bad press, and operational disruptions.

 

How to mitigate threat exposure

Unfortunately, eradicating threat exposure is mission impossible. This leaves businesses with the second-best option — working tirelessly to mitigate it. Here are some tips on how companies can do this effectively.

Find all possible attack vectors

An attack vector is a specific path malicious actors can take to breach the company’s systems. The total of these attack vectors constitutes the organization’s attack surface, which is part of the company’s overall threat exposure. Employing security teams to find all possible attack vectors is crucial in defining and mitigating cyber risks. Regular system testing should be a norm for any business that aims to see a clear picture of its cybersecurity, review system vulnerabilities, and improve its threat exposure management.

Use cyber threat intelligence

Cyber threat intelligence is a cybersecurity field that aims to gather knowledge about all the existing and developing cyber risks, including their trends and advancements. Like the stock market, actively following updates and news in threat intelligence can provide new opportunities, enhance understanding (in this case, of potential attack paths), and reduce the risk of data breach (and, therefore, financial loss). Similar to how investors analyze trends to make informed decisions, businesses must stay ahead of emerging threats to defend against potential risks.

Implement security controls

Continuous threat exposure management requires setting up robust security controls. These include enabling two-factor authentication (2FA), network segmentation, and incident response plans. With numerous options at their disposal, businesses can and should upgrade their systems to withstand even the most ferocious brute-force cyberattacks.

Constantly monitor potential cyber threats

In cybersecurity, vigilance can be a lifesaver. Constantly monitoring the system will help security teams spot data breaches faster. Early detection provides additional time to safeguard sensitive data before hackers can exploit system vulnerabilities. Businesses can leverage NordStellar, a comprehensive threat exposure management platform, to enhance cyber threat monitoring. The platform helps security teams identify and respond to cyber threats before they escalate, reducing data leak detection times, improving compliance, and strengthening the online security of employees, clients, brands, and infrastructure.

Educate employees on workplace cybersecurity

Cyberattacks often result from human error. For example, some of the most notorious data breaches have occurred because of an employee clicking on a phishing link (Marriott data breach in 2018) or being tricked into providing login credentials through social engineering (Twitter Bitcoin scam in 2020).

Regularly training and educating employees on cyber vulnerabilities in their workplace can further reduce a company’s threat exposure. While it may initially seem challenging, this strategy could benefit not only the business but also employees’ personal online safety.

Minimize third-party access to sensitive data

Threat exposure also includes risks posed by third-party service providers, often referred to as supply chain cyberattacks. To protect themselves, businesses that rely on third-party services should avoid providing credentials to the inside platforms and, if possible, have separate systems for sharing important information. That way, if a third-party service provider suffers a data breach, the hackers won’t have direct access to the company’s data.

Keep the existing security controls up to date

Online security systems become obsolete quickly. Meanwhile, threat actors continue to improve, finding new ways to breach targets’ systems. Keeping an organization’s cybersecurity measures up to date is critical to safeguarding business or client data. Therefore, security patches and updates should be installed as soon as they are released.
