THC HYDRA
Hydra was a software project developed by a German organization called “The Hacker’s Choice” (THC) that uses a dictionary attack to test for weak or simple passwords on one or many remote hosts running a variety of different services. It was designed as a proof-of-concept utility to demonstrate the ease of cracking poorly chosen passwords.
The project supports a wide range of services and protocols: 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, LDAP, PostgreSQL, Teamspeak, Cisco auth, Cisco enable, and Cisco AAA. It is licensed under version 2.0 of the GNU General Public License with the additional terms that the software may not be used for illegal purposes, and any commercial service or program that uses Hydra must give credit to THC.
