Abstract
Brute force attacks on a given account with various password attempts are a common threat to computer security. When a suspected brute force on an account is detected, systems may lock the account from access, which is frustrating to users and time consuming for administrators in the event of a false positive. To reduce the number of false positives, brute force counterattacks are taught in the present disclosure. A brute force counterattack is used to learn whether the login attempts change the passwords attempted, and are to be classified as malicious, or keep the attempted password the same in multiple attempts, and are to be classified as benign.
