Security researchers have discovered what appears to be the largest password leak of all time, containing around 10 billion unique plaintext passwords. The file, titled “rockyou2024.txt,” was posted on a leading hacking forum by a hacker using the name “ObamaCare.”
The passwords didn’t leak in a single data breach; they are part of both old and new data breaches. This is bad news for everyone because hackers can use these passwords to access not only your personal data but also your financial information, especially if you use the same password for multiple services.

What you need to know about RockYou2024 leak
The massive trove of passwords was discovered by researchers at Cybernews, who believe the leak poses severe dangers to users prone to reusing passwords. The report revealed that the password file, which was posted on BreachForums criminal underground forum, contained an astonishing 9,948,575,739 unique passwords, all in plaintext format.
According to Cybernews, RockYou2024 isn’t an entirely new leak. It apparently comprises an earlier credentials database known as RockYou2021, which featured 8.4 billion passwords. The hackers scoured the internet for data leaks, adding another 1.5 billion passwords from 2021 through 2024, increasing the dataset by 15 percent.
“In its essence, the RockYou2024 leak is a compilation of real-world passwords used by individuals all over the world. Revealing that many passwords for threat actors substantially heightens the risk of credential stuffing attacks,” researchers said, noting that they cross-referenced the passwords included in the RockYou2024 leak with data from Cybernews’ Leaked Password Checker.
ObamaCare, the forum member who posted the password file, registered on the forum in May this year but has already leaked multiple other databases. For instance, they have previously shared an employee database from the law firm Simmons & Simmons, a lead from the online casino AskGamblers, and student applications for Rowan College at Burlington County.

How does this leak affect you?
The password leak puts you at risk of credential stuffing attacks, which can be very damaging. Credential stuffing is when someone takes passwords from one data breach and tries to use them to log into other services.
For example, a hacker might use passwords from an AT&T breach or a previous breach with 26 billion records to see if you use the same password for your bank account.
“Threat actors could exploit the RockYou2024 password compilation to conduct brute-force attacks and gain unauthorized access to various online accounts used by individuals who employ passwords included in the dataset,” the researchers explained.

How can I check if my information was sold on the dark web?
What do I do if my data has been stolen?
If you think you may have been affected by the massive password leak, follow these tips to safeguard yourself.
1) Change your passwords: Never use the same password for multiple services you use. If you recall adding the same password on different apps or websites, consider changing it to something different. Consider using a password manager to generate and store complex passwords.
2) Set up two-factor authentication (2FA): 2FA is an extra shield that prevents hackers from accessing your accounts. It requires that after entering your password, you add another piece of information. This could be a code sent to your phone via SMS, a code generated by an authenticator app, a fingerprint scan, or a hardware token.
3) Remove your personal information from the internet:

4) Use a VPN: Consider using a VPN to protect your online activity and data. VPNs will protect you from those who want to track and identify your potential location and the websites that you visit.
My top recommendation is ExpressVPN. It has a quick and easy setup, is available in 105 countries, and will not log your IP address, browsing history, traffic destination or metadata, or DNS queries.
Right now you can get 3 extra months FREE with a 12-month ExpressVPN plan. That’s just $6.67 per month, a saving of 49%! Try 30 days risk-free.
5) Monitor your accounts: Regularly review your bank statements, credit card statements, and other financial accounts for any unauthorized activity. If you notice any suspicious transactions, report them immediately to your bank or credit card company.
Kurt’s key takeaway
The RockYou2024 leak is a wake-up call for everyone who uses the internet. It shows that even the data you entrust to companies might not be completely safe. While we can take steps to protect ourselves, the real responsibility lies with the apps and services we rely on. They need to step up their security game to prevent these huge data breaches from happening in the first place.
