This page will contain tools I find useful or just interesting. Over time, I expect to provide tutorials for some of them as well.
Getting things started:
Armitage - http://www.fastandeasyhacking.com/
A great front end for Metasploit, now included with every Metasploit download!
Cain & Abel - http://www.oxid.it/cain.html
Fantastic set of tools all rolled into a single graphical Windows Program. One of my favorite tools for MiTM attacks (And great for quick VoIP testing)
Little Black Box - https://code.google.com/p/littleblackbox/
LittleBlackBox is a collection of thousands of private SSL and SSH keys extracted from various embedded devices. These private keys are stored in a database where they are correlated with their public certificates as well as the hardware/firmware that are known to use those private keys.
