Cracking 400,000 Passwords, or How to Explain to Your Roommate why the Power Bill is a Little High…

Remember when phpbb.com was hacked in January and over 300,000 usernames and passwords were disclosed? Don't worry though, the hacker only tried to crack a third of them, (dealing with big password lists is a pain), and of those he/she only broke 24%. Of course the cracked password weren't very surprising. Yes, we already know people use "password123". What's interesting though is figuring out what the other 76% of the users were doing. In this talk I'll discuss some of my experiences cracking passwords, from dealing with large password lists, (89% of the phpbb.com list cracked so far), salted lists, (Web Hosting Talk), and individual passwords, (TrueCrypt is a pain). I'll also be releasing the tools and scripts I've developed along the way.
