The file xato-net-10-million-passwords.txt is a publicly available wordlist containing 10 million unique plaintext passwords. Originally compiled by researcher Mark Burnett from various data breaches (e.g., LinkedIn, RockYou, MySpace, and other leaks prior to 2014), it has become a standard tool for penetration testing, password policy auditing, and academic research into user behavior. This paper examines the dataset’s composition, common findings, and its implications for modern cybersecurity.
