THC-Hydra is very popular Multi-Platform Password Brute Force Tool ( especially for HTML Login Form password brute force ). THC.org does not provide a compiled version of Hydra for Windows Platform, you need to compile it from source with Cygwin environment.
I have pre-compiled a newest version of Hydra ( ver 7.2 on 11 Feb 2012 ) . You can download it here
