Prompt: “Guess passwords”
Hackers have always used the latest technologies to make their attacks more effective—and now, of course, they’re using AI. It turns out artificial intelligence has many applications for cybercriminals, from creating personalized phishing messages and advanced malware to, that’s right, guessing people’s passwords.
As a result, instead of trying to hack passwords manually—a process that could take years if they’re even slightly more complex than “123456”—cybercriminals now use AI models to generate highly accurate password predictions based on a target’s online behavior and data. This allows them to launch optimized brute-force attacks, significantly increasing their chances of gaining unauthorized access to company systems and devices.
What our research shows—and what hackers know all too well—is that weak password habits are common across industries. And since most companies still rely on passwords to protect their digital assets, it’s no surprise that cybercriminals are using artificial intelligence to exploit this vulnerability. With AI on their side, they’ve got a better shot at breaking into a company, disrupting its operations, and putting its brand reputation at risk.
How does AI improve password guessing?
It’s simple—AI leaves traditional password-guessing methods in the dust when it comes to both speed and accuracy. Unlike humans, AI isn’t limited by having to type things out on a keyboard. And, unlike traditional brute-force tools, it doesn’t waste time trying every possible combination of letters, numbers, and symbols.
No, AI plays it smart. For instance, it analyzes massive datasets of leaked passwords to find patterns in how people often create passwords, identifying popular formulas like [pet’s name]+[year of birth] or [company name]+123. Some AI tools even gather data from social media or company websites to increase their chances of guessing a password by using employees’ personal information and company-related terms. Not to mention the fact that artificial intelligence also understands all human languages, so it knows what phrases people are more likely to use in their country.
Because of all that, AI doesn’t waste its resources on trying millions of irrelevant combinations—it jumps straight to the most likely guesses. So, if your password is weak and predictable, an AI tool could probably guess it in a matter of minutes.
This is a serious issue for all businesses. Google’s Threat Horizons Report found that over 60% of the breaches it analyzed involved credential issues. Therefore, all companies must enforce a strong password policy before AI-powered password guessers become a major threat to their operations.
The difference between guessing and cracking passwords
Although both fall under the umbrella of “password hacking,” “password guessing” and “password cracking” are two different things. The former describes a trial-and-error process of attempting as many password guesses as possible until one eventually hits the jackpot.
Password cracking, on the other hand, is about decrypting password hashes from a stolen password database. In other words, hackers already have the credential data in their possession, but it’s still protected by encryption. So, they use cracking tools to uncover plaintext passwords.
Who’s most vulnerable to AI password attacks?
While anyone is at risk from AI-powered password guessers, businesses are likely the biggest targets. That’s because companies have a much larger attack surface, and sometimes just one compromised business password can give cybercriminals access to an entire IT ecosystem.
Hackers are also using AI to target corporate platforms to reap bigger profits than they’d get from breaking into individual user accounts. It’s like the saying goes: “The greater the risk, the greater the reward.”
Tips for protecting business passwords from AI
While the threat of AI-powered password guessers may seem daunting, you’re not helpless or without options. There are several strategies and tools that, if implemented correctly, can help protect your business. Here are some of them:
Enable multi-factor authentication (MFA)
Relying only on passwords to protect your company accounts isn’t enough these days. You need extra layers of security so that even if a password is compromised, your systems and data stay safe. That’s where multi-factor authentication comes in.
By setting up MFA on all your company accounts, you ensure that anyone trying to log in will need more than just a password to gain access. As a result, even if an AI-powered password guesser figures out the user’s credentials, hackers still won’t be able to get in.
Don’t reuse passwords
If an employee uses the same password across multiple accounts—both business and personal—they may be doing more harm than they realize. If an AI tool cracks such a password, hackers could break into several company systems at once, making it a nightmare for your IT team to contain the damage. That’s why it’s so important to have a strong password policy that prevents password reuse in your organization.
Educate your team
It’s one thing to ask employees to follow security rules—it’s another to make sure they understand why those rules matter. Investing in cybersecurity training sessions is not only a way to teach your team how to use company systems safely and spot phishing attempts, but it also helps them see the bigger picture behind the risks the company is facing—and how their actions can affect your entire organization. When your employees understand the threat, know what to watch for, and how to respond, you’re much more likely to catch issues early and reduce the chance of human error.
Keep software and devices updated
Most of the tools and systems companies rely on get regular updates to fix bugs and patch up security holes. That’s why it’s really important to make sure all your company’s devices and software stay up to date. Without those updates, you could be leaving vulnerabilities that hackers are just waiting to exploit.
Use a password manager
If your company doesn’t use a password manager yet, getting one should be at the top of your priority list. Why? First of all, a password manager like NordPass allows your employees to generate strong, hard-to-guess passwords for each of their business accounts. It also lets them securely store, manage, autofill, and share those passwords internally with the team. So if you’re concerned about AI-powered password guessers, using a tool like NordPass is one of the best ways to stay ahead.
NordPass also offers additional security features, such as a Data Breach Scanner that informs you if your company’s credentials have been compromised, Password Policy that allows you to enforce strict password rules for all employees, and Email Masking, which hides users’ real business email addresses when signing up for newsletters or online services. With features like these, you’ll have more control over access to your company’s systems—and help protect your business data from threats like AI password guessers.
Bottom line
Hackers are now using AI to guess business passwords based on the targets’ online behavior and data. With this technology, cybercriminals can crack weak passwords in just a few minutes, gaining access to company systems at lightning speed.
To protect themselves, organizations must make sure that all employees use only strong, AI-proof passwords. One way to do this is by investing in tools like password managers (e.g., NordPass) that can generate complex passwords on the spot and securely store each employee’s credentials in encrypted vaults.
