UserlistGenerator

UserlistGenerator is a Rust tool for generating lists of usernames to be used in brute-force attacks. It creates permutations of names from a wordlist file, providing lowercase and optional uppercase variations. This tool is especially useful in conjunction with Kerbrute.

Compiling the Rust Script

To compile the Rust script, run the following command:

rustc userlistgenerator.rs

Using the Compiled Executable

After compiling the Rust script, you can use the generated executable as follows:

./userlistgenerator -w <wordlist> [-u]

Options

• -w, --wordlist <FILE>: Specify the path to the wordlist file.
• -u, --uppercase: Also produce uppercase permutations. Disabled by default.

Example wordlist

James Howlett
Ip Man

Example output with lowercase permutations only

./userlistgenerator -w username.lst

What is Kerbrute?

Kerbrute is a tool used for performing Kerberos pre-authentication brute-force attacks. It's commonly used for testing password policies and assessing security risks.
