We ran the Project 2 contest at Defcon 20, July 26-29 2012. The contest was designed to appeal to beginners, ramping up to puzzles which would intrigue the most skilled hackers.
We had 108 teams register, with 58 scoring points. Given that teams may have consisted of multiple players, this made Project 2 one of the largest contests at Defcon.
The winners were team swordfish, consisting of David and Aviel. Their prize was a can of pringles, and a lot of photos with the 2012 Rollercon Mountain Cats (Roller Derby team).
Nearly every puzzle was solved this year! This means we are going to have to do a lot of work in the next 12 months. We're happy people enjoyed the contest and look forward to confounding you again in 2013.
