Each month I create a new challenge for the Dallas Hacker’s Association (DHA) that involves elements of logic puzzles and cryptography, and award some prize to whomever first solves it. I have decided to start posting those challenges to this site as well for those who either can’t attend or want to play remotely. I will then provide the solutions to the challenges three months later in a separate article. This was the sixth official challenge for DHA that was released in September of 2023.
