In a reverse brute-force attack, a single (usually common) password is tested against multiple usernames or encrypted files. The process may be repeated for a select few passwords. In such a strategy, the attacker is generally not targeting a specific user. Reverse brute-force attacks can be mitigated by establishing a password policy that disallows common passwords.
