Cain

Cain is a leading security tool to scan your local network and your own PC for passwords.

It runs under Windows so the installation is quite simple. Furthermore, it comes with a detailed user guide to help you get started. You can configure Cain to intercept passwords for e-mail, Internet, database passwords and so on. What’s more, Cain is able to record VOIP, or telephone calls made over the Internet. It’s a very handy tool since you can use Cain to crack your own password protected files, such as Word or Access. It’s most powerful feature is the so-called “man in the middle” attack whereby you can intercept any traffic floating on your local area network. Combined with a powerful password intercepting technique, all you have to do is to sit back and watch the passwords appear of other users inside your network as well as the websites they visit.
