What is hydra?

Hydra is simply a network password/login cracker, it uses brute-forcing and supports many protocols.

Number one of the biggest security holes are passwords, as every password security study shows.
Hydra is a parallized login cracker which supports numerous protocols to attack. New modules
are easy to add, beside that, it is flexible and very fast.

Version 6 was tested to compile cleanly on Linux, Windows/Cygwin, Solaris 11, FreeBSD 8.1 and OSX.

Currently this tool supports:
TELNET, FTP, HTTP, HTTPS, HTTP-PROXY, SMB, SMBNT, MS-SQL, MYSQL, REXEC, RSH, RLOGIN, CVS, SNMP, SMTP-AUTH, SOCKS5, VNC, POP3, IMAP, NNTP, PCNFS, ICQ, SAP/R3, LDAP2, LDAP3, Postgres, Teamspeak, Cisco auth, Cisco enable, AFP, Subversion/SVN, Firebird, LDAP2, Cisco AAA (incorporated in telnet module).
For HTTP, POP3, IMAP and SMTP, several login mechanisms like plain and MD5 digest are supported.

This tool is a proof of concept code, to give researchers and security
consultants the possiblity to show how easy it would be to gain unauthorized
access from remote to a system.

So yeah, Hydra v6 was finally released yesterday (2011-01-24)

Note: you can get the source from here (official hydra-6.0-src.tar.gz) or (my mirror).
I compiled it under windows in a few minutes (and you should do the same)

If you hate dealing with cygwin or just lazy, here are the binary files:
