This month we flew out to scenic Las Vegas, Nevada to take on some of the world’s most notorious hackers (that's us!) in the annual DEFCON 23 Network Forensics Puzzle contest, organized by LMG Security. For those of you who aren’t familiar with the contest, you and your team get several encrypted files, one per round, at the start of the contest. The organizers give you the key to the first file, which typically contains pcaps or other network traces, and a simple question to answer. Your job is to use the files to answer the question. Once you are confident the team has answered the question, you text the answer to the organizers and they will text back the key to the next round if you are correct. Wild guessing is discouraged and may lead to the organizers disqualifying the team. To finish, successfully answer the question in each round.
