According to CyberNews, a huge text file of about 100 GB in size was published on a popular hacker forum, which contains 8.4 billion passwords obtained as a result of various leaks and data breaches.
According to the author of the file, all passwords are between 6 and 20 characters long. He claims that the collection contains 82 billion passwords. However, CyberNews calculated that the actual number turned out to be almost ten times less – 8,459,060,239 unique records.
Back in 2009, there was a huge data breach called RockYou. At the time, “attackers compromised the servers of the social application site and obtained over 32 million user passwords stored in plain text.” The new collection of passwords is called RockYou2021.
Previously, the largest data breach involved 3.2 billion email / password combinations. The information was created based on existing data stolen from companies such as Netflix and LinkedIn. The new collection contains more than 8.4 billion passwords, while the population of our planet is less than 8 billion people, and the Internet users are only about 4.7 billion people. Chances are your passwords are also on this list.
By combining 8.4 billion unique password choices with other hack compilations that include usernames and email addresses, attackers can use the RockYou2021 collection to create a password dictionary and password attacks against countless online accounts. Since most people reuse their passwords across multiple applications and websites, the number of accounts affected by this leak could potentially reach millions, if not billions.
CyberNews also offers to check if your passwords are in this database.
