Win Brute Logon is designed to simulate a brute-force attack on a Microsoft account by guessing large numbers of password combinations in a short amount of time. This allows pentesters to test the security posture of their systems and assess their defenses against brute-force attacks. The tool exploits the lack of an account lockout mechanism, which is a common weakness in many systems (before account lockout becomes enabled by default on Windows 11). By attempting to guess the password of an account, the tool can help pentesters identify and address vulnerabilities in their security measures. It should be used responsibly and within the bounds of the law.
