Description

Hydra is a multi-protocol, parallelized authentication brute forcer. By assigning many parallel tasks, remote login brute forcing can be accelerated SIGNIFICANTLY, however it depends on the protocol. The fastest is generally POP3, then FTP, then Telnet, and the least IMAP. Experiment with the task option (-t) to speed things up. The higher, the faster (but too high, and it disables the service). To prevent disabling you can now use the -g option for "slow-starts". Currently this tool supports: TELNET, FTP, HTTP, HTTPS, HTTP-PROXY, LDAP, SMB, SMBNT, MS-SQL, MYSQL, REXEC, SOCKS5, VNC, POP3, IMAP, NNTP, PCNFS, ICQ, SAP/R3, Cisco auth, Cisco enable, Cisco AAA. Flavors: * no_x11 - do not build GTK frontend.
