To check if your password is part of the leak, you can use Cybernews' Leaked Password Checker1. Enter your password, and the tool will cross-reference it against the database of leaked passwords. If your password is found in the database, change it immediately to a strong, unique password and enable multi-factor authentication if available. A password manager can help keep your passwords organized and secure.
Credential stuffing is a cyber attack where hackers use stolen login credentials, typically usernames and passwords, from one data breach to gain unauthorized access to user accounts on other unrelated systems25. This is possible because many users reuse the same username/password combination across multiple sites, making it easier for attackers to compromise those accounts.
The RockYou2024 file increases the risk of attacks by compiling nearly 10 billion unique plaintext passwords from various data breaches into one massive, searchable database. This makes it easier for hackers to perform credential stuffing attacks, where they use leaked passwords from one breach to attempt to log into unrelated services, exploiting the common practice of reusing passwords across multiple accounts.
