Defcon Mystery Challenge

Looks like Defcon 16 is one of the best yet. The “Defcon 16 Mystery Challenge” is a competition for attendees to have at. Solve a series of puzzles and mysteries and you could win special black Defcon badges that give you free admittance for life. One of the puzzles includes this delightful yellow ball with a combination lock on the top. You say lockpick it, I say smash it.
