Brutus - a Brute force online password cracker
Brutus is an online based password cracker.
It works by trying to break telnet, POP3, FTP, HTTP, RAS or IMAP by simply trying to login as a legitimate users. Brutus imitates a real outside attack (unlike other password cracking applications that simulate an internal attack) and thus serves as a valuable security-auditing tool.
Brutus can run in single user mode (trying to break into a single user's account by trying different password combinations) or by trying a list of user/password combinations from a word file. The application scans the host for known services and can be easily customized to break-in any other custom service requiring interactive logon of a username and a password.
Using Brutus will teach you a lot about your system, since it simulates a real attack. To make a good use of Brutus's attack simulation an administrator should that note whether the break-in attempts are logged, and whether a timeout is issued after a few failed logins - this can be easily seen by the progress Brutus is making.
