Have any of you done any CTF competitions at a security conference? This year I want to go to Derbycon and like most cons I think they are going to do a CTF competition. I would like to participate but I have never been involved with anything like that. If any of you have, how did you prepare for it? Did you have a team or did you go by yourself? Any tips or tricks?
This is a pretty good write up of last years CTF at Derbycon
