Active Directory Hacking: Enumerating Users & Password Spraying with Kerbrute!

One of the first steps in compromising an Active Directory environment is to find valid users. In this video, I provide a detailed guide on how to use Kerbrute to identify valid usernames in Active Directory! Kerbrute sends TGT requests without pre-authentication to enumerate usernames. A "PRINCIPAL UNKNOWN" error means the username doesn't exist, while a pre-authentication prompt confirms it does. This method avoids login failures and account lockouts, but generates Windows event ID 4768 if Kerberos logging is enabled. ---- Kerbrute: https://github.com/ropnop/kerbrute Hack Smarter: https://hacksmarter.org ---------- This content is intended for educational purposes only.
