sucrack

multithreaded su bruteforcer

sucrack is a multithreaded Linux/UNIX tool for cracking local user accounts via wordlist bruteforcing su. This tool comes in handy when you've gained access to a low-privilege user account but are allowed to su to other users. Many su implementations require a pseudo terminal to be attached in order to take the password from the user. This can't be easily achieved with a simple shell script. This tool, written in C, is highly efficient and can attempt multiple logins at the same time.
