Description:
The massive RockYou2024 leak exposes nearly ten billion unique passwords on a hacking forum, posing significant risks to users who reuse passwords. Cybernews research warns of potential threats from this extensive data breach.
The Largest Password Compilation in History
Cybernews researchers have uncovered what is now the largest known compilation of passwords, boasting a staggering 9,948,575,739 unique plaintext passwords. This colossal dataset, titled rockyou2024.txt, was posted on July 4th by a forum user known as ObamaCare.
This user, who registered in late May 2024, has a history of sharing sensitive data, including an employee database from the law firm Simmons & Simmons, records from the online casino AskGamblers, and student applications for Rowan College at Burlington County.
The Cybernews team cross-referenced the RockYou2024 passwords with their Leaked Password Checker, revealing that the compilation is a blend of both old and new data breaches.
The Danger of Credential Stuffing Attacks
“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 stated.
Credential stuffing attacks, where attackers use lists of compromised passwords to gain unauthorized access to accounts, can be highly damaging. Recent attacks targeting companies like Santander, Ticketmaster, Advance Auto Parts, and QuoteWizard were linked to credential stuffing against their cloud service provider, Snowflake.
The Cybernews team explained, “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.”
A History of Massive Data Breaches
The RockYou2024 compilation did not appear out of nowhere. Three years ago, Cybernews reported on the RockYou2021 password compilation, then the largest at 8.4 billion plaintext passwords. Attackers developed RockYou2024 by scouring the internet for data leaks, adding another 1.5 billion passwords from 2021 to 2024, increasing the dataset by 15%.
The original RockYou2021 compilation stemmed from a 2009 data breach and included millions of user passwords for social media accounts. Over time, this compilation has grown exponentially. The latest RockYou iteration likely includes information from over 4,000 databases collected over more than two decades.
The Cybernews team believes that attackers can use the ten-billion-strong RockYou2024 compilation to target any system not protected against brute-force attacks. This includes everything from online and offline services to internet-facing cameras and industrial hardware.
“Moreover, combined with other leaked databases on hacker forums and marketplaces, which, for example, contain user email addresses and other credentials, RockYou2024 can contribute to a cascade of data breaches, financial frauds, and identity thefts,” the team noted.
Protecting Against RockYou2024
While there is no foolproof way to protect users whose passwords have been exposed, impacted individuals and organizations should adopt mitigation strategies. The Cybernews research team recommends:
- Immediately resetting passwords for all accounts associated with the leaked passwords. It is crucial to choose strong, unique passwords that are not reused across multiple platforms.
- Enabling multi-factor authentication (MFA) wherever possible. This enhances security by requiring additional verification beyond a password.
- Utilizing password manager software to securely generate and store complex passwords. Password managers help mitigate the risk of password reuse across different accounts.
Cybernews will incorporate data from RockYou2024 into their Leaked Password Checker, allowing users to verify if their credentials were exposed in this latest massive leak.
Earlier this year, Cybernews also uncovered the “Mother of all Breaches” (MOAB), a monumental 12-terabyte breach comprising over 26 billion records. The RockYou2024 leak marks yet another record-breaking compilation revealed online in 2024.
