Congratulations to all the teams that participated in the Network Forensics Puzzle Contest this year, and especially to our top three finishers! This year marked our sixth year running the contest, so we were happy to see a number of familiar faces at our booth as well as lots of first-time players.
The winners are…
1st place – Threat Level Pancakes
2nd place – Tom Pohl
3rd place – Blue Squirrel
The contest consisted of six rounds plus a bonus round. The leading teams breezed through the first few rounds before hitting challenging rounds 5 and 6. Three teams persevered for over 36 hours and successfully completed the puzzle. The bonus round remains unsolved. We hope you picked up a disc so you can give it a try at home!
The full top 10 leaderboard is below.
An impressive 71 teams completed round 1. That number quickly dwindled down to 11 round 5 finishers, and just three round 6 finishers.

Finally, it’s what you’ve all been waiting for: the walkthrough and solutions to this year’s puzzle! When you’re ready to see how it’s done, click on the jump to view the walkthrough.
Congratulations to the top 10 teams in this year’s contest! All 10 completed the first five rounds of this challenging puzzle. A special congratulations goes to the top three teams, who completed all seven rounds.
The first place team, Dofir, walked away with an iPod touch. Tom Pohl and Team Blue, who tied for second, earned a ION Mini Block Rocker and a portable touchpad, respectively. An Amazon Fire Tv, the prize for the first person or team to complete the bonus round, is still waiting for someone to claim it!
The puzzle was meant to get more difficult as it progressed, but several other factors affected the average duration of each round of the puzzle. We calculated the time to complete round one based on the time the contest started: Thursday, August 7 at noon–but clearly not everyone got started that early. The other averages are based on the time since that team completed the previous round.
The times were also affected by the decreasing number of competitors that completed each successive round. By round 5, for example, only a modest 12 teams were still playing, and they had the experience to complete the round relatively quickly. 264 teams registered to play, and 63 completed the first round while at DEFCON.
Stuck on a round of the puzzle? We can help you out. Here is the list of hints we released at DEFCON.
Round 1: All your base 64 are belong to us.
Round 2: Encode-ception.
Round 3: Snowden’s-eloquent-quotes.jpg
Round 4: @ is a common symbol used with device names.
Round 5: Satellite connect-the-dots.
Round 6: The image from round 3 is more than meets the Eye. (There is a hint in round 1.)
Good luck!

We are pleased to be giving an Amazon Fire TV to the first team to complete the bonus round of this year’s Network Forensics Puzzle Contest. You don’t need to complete all the other rounds to be in the running, just the eighth bonus round.
Our contest phone will be deactivated soon, so please submit your answers to myself at asawyer[at]lmgsecurity[dot]com or my colleague Bryan at bschmidt[at]lmgsecurity[dot]com. Good luck, and we look forward to seeing your solutions!
Congratulations to all the teams who entered and competed in this year’s Network Forensics Puzzle Contest at DEFCON 22. This was our fifth year running the contest, and we saw an incredible turnout of 264 registered teams for one of our most challenging puzzles ever. It was ultimately a test of endurance: teams were required to beat seven progressively more difficult rounds, with the winning team finishing in just over two days.
The eighth bonus round of the contest was attempted by the top three teams but went unsolved at DEFCON. We will ship the prize (an Amazon Fire TV) to whomever can successfully solve the bonus round first! We have a small confession: no one has solved this round yet (including the creators of the puzzle), so we will be impressed to see a solution.
The top 3 finishers:
1st place: Dofir (49 hours, 3 minutes)
2nd place (tie): Tom Pohl and Team Blue (52 hours, 7 minutes)
We hope you grabbed a disc even if you didn’t have time to play along at DEFCON so now you can check out the puzzle on your own. As promised, here are the passwords to unlock the Truecrypt volumes for each round. Please note that zeroes are often used instead of the letter ‘o.’

Network Forensics Puzzle Contest #10 posed a serious challenge, requiring contestants to demonstrate advanced reasoning and meticulous attention to detail, even when reading the scenario. Thank you to everyone who submitted an entry for Puzzle #10, and a special congratulations to the relatively small number of folks who submitted correct answers.
The winner of this contest is…Steve B. ! Steve was both the first person to solve the contest AND the person to have the most eloquent solution. He’ll be receiving a prize for being first and the Blackhat Black Card! We’ll be posting a walkthrough and answers in the coming weeks. Steve wrote a great write-up [available here].
