We recently participated in the Yours Truly puzzle created by Josie Bellini (@josiebellini) and managed to secure a victory by being the first to solve the entire puzzle series. Here is a walkthrough of all the puzzles and how to unlock Josie’s Yours Truly puzzle wallet.

Brett, Jon, and I teamed up with Council of 9 and won this years badge challenge after having great success in the DEFCON 22 Badge Challenge. Over the last year we have studied a huge number of cryptographic methods and ancient languages to prepare for this. We also released our own crypto-challenge website for the community to follow along and have fun challenging themselves. With our new knowledge and a great team in tow we headed out to DEFCON.
Here is the entire adventure as we experienced it with all of the puzzles, their solutions, and the steps to solve them. Understand that this document contains MASSIVE spoilers so if you do not want to ruin it for yourself please stop reading now.
