Password cracking has made major advances in recent years with the introduction of GPU-based cracking. Many organizations are turning to GPU cracking to audit passwords and ensure compliance with password complexity policies. In this talk, we will walk you through how we were able to build our own cracking system with high-end gaming parts, for minimal cost. We'll be honest and let you know how we screwed up and how we succeeded. Additionally, there will be demos of our GPU cracking rig's performance along with tips and tricks for building your own cracking box, both the cheap way and the right way.
