Ethical hacking tools and techniques: Password cracking
E-mailPrintAAAAAALinkedInFacebookTwitterShare ThisReprints
Password cracking doesn't have to involve fancy tools, but it's a fairly tedious process. If the target doesn't lock you out after a specific number of tries, you can spend an infinite amount of time trying every combination of alphanumeric characters. It's just a question of time and bandwidth before you break into a system.
The most common passwords found are password, root, administrator, admin, operator, demo, test, webmaster, backup, guest, trial, member, private, beta, [company_name] or [known_username].
There are three basic types of password cracking tests that can be automated with tools:
Dictionary - A file of words is run against user accounts, and if the password is a simple word, it can be found pretty quickly.
Hybrid - A common method utilized by users to change passwords is to add a number or symbol to the end. A hybrid attack works like a dictionary attack, but adds simple numbers or symbols to the password attempt.
Brute force - The most time-consuming, but comprehensive way to crack a password. Every combination of character is tried until the password is broken.
Some common Web password cracking tools are:
Brutus is a password cracking tool that can perform both dictionary attacks and brute force attacks where passwords are randomly generated from a given character. Brutus can crack the multiple authentication types, HTTP (Basic authentication, HTML Form/CGI), POP3, FTP, SMB and Telnet.
WebCracker is a simple tool that takes text lists of usernames and passwords, and uses them as dictionaries to implement basic authentication password guessing.
ObiWan is a Web password cracking tool that can work through a proxy. ObiWan uses wordlists and alternations of numeric or alpha-numeric characters as possible passwords.
