The majority of the kiddies in the contest don't know shit from Shinola. It's the few that DO know what they are doing that worry me. On the 5th I plan to kill FTP and SSH access on my servers and basically only leave the vital services running. It's better to be safe than sorry.
The website for their little contest was
http://www.defacers-challenge.com which seems to be tits up at the moment.
