My co worker just showed me your site. I worked on the DC3 this year. I would love to be made aware of the next contest. It seems like a lot of fun.
Hello, I was at the Defcon 19 and I picked up the current puzzle for this year. I was not able to participate in the competition as it was occurring, but I still wanted to play the game. I took a picture of the Keys for truecrypt. I got passed the 1st round, I was about to play the second round but noticed that the password does not work. (!n1c3w0rk). I also tried the passwords for the other rounds and the 5th round doesn’t seem to work as well. Can you please let me know if there is a mistake here somewhere, I would like to go through this puzzle, it is a lot of fun to play. I may play the older puzzles in the mean time, but I hope to get the password for the current one. Also I noticed that there are 7 passwords listed on the sheet. Is this part of the puzzle ? Thanks for challenges.
