kerbrute

Kerbrute is a Python script designed for performing brute-force attacks on Kerberos authentication using the Impacket library. It accepts user and password lists to enumerate valid username/password pairs, valid usernames, and those that do not require pre-authentication, while generating a list of valid credentials and retrieved TGTs. Notable features include multithreading support, customizable output options, and the ability to handle input files for users and passwords.
