sucrack - 1.2.3-7+b1 main

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.
