One of the coolest things at Defcon this year was the wall of sheep. You don't go into a hacker conference expecting that your wireless is safe and not being monitored. Apparently the ATM's (or ABM's depending on where you're from) were hijacked last year, so this isn't your mother's hacker conference.

Anyways, the wall of sheep was a list of all the usernames and passwords (at least part of them) and what was being logged into (e.g SMTP, ICQ, Webmail) that were hijacked at the conference. All this information was projected onto a wall at Defcon for everyone to see. It's humbling to see that, even at a conference full of people who are admittedly blackhats, people still don't pay attention to who might be watching.

It was quite funny to see the name of someone quite famous in the security industry scroll by as we were standing there. What made it even funnier is that they explicity were talking about how one does NOT want to be on that wall prior to showing up at Defcon and how they should not use "unencrypted anything" at one of these hacker conferences. Karma can be a major pain sometimes.

Come to think of it, hopefully I wasn't on that list.........
