Cracking corporate passwords is no different than cracking public MD5 leaks off of pastebin. Except, it totally is. Corporate passwords are not in the same formats you are used to, they require capital letters, numbers and/or special characters.
- How can we use this knowledge to our advantage?
- What sort of tricks are users doing when they think no one is looking?
- What other types of vulnerabilities is Password policy introducing?
- What patterns is password rotation policy creating?
You want raw data? Ive got raw data!
You want to see some stats? Ive got those too.

Lastly, Rick will tell about how KoreLogic implements/manages large-scale cracking jobs on a diverse set of CPUs/GPUs located nation-wide against corporate password lists.
