CIPHER 5

July 10th, 2009

Yesterday I competed in the CIPHER 5 competition.  It was a fun challenge, but I wasn’t a big fan of the competition itself.  The scoring system was very unreliable, and we developed an exploit we were unable to use because the scorebot went down for a while.  Teams are supposed to get points for writing vulnerability advisories, but ours were rejected for vague reasons.

Not that any of that mattered, because the team affiliated with the host of the competition jumped straight to the top of the scoreboard and never left the #1 spot.  Nobody else even came close.  Big surprise there.

I had a lot more fun last year competing in the UCSB iCTF – that one was very smooth, functional, diverse, and interesting.  I haven’t heard if there’s another one this year, since (I think) that crew is doing the CTF for Blackhat, but I hope so.
