A few years ago I participated in the AIVD's cyber challenge. It involved reverse engineering an executable, spotting a flaw in the (custom) crypto algorithm which made it brute-forcable and then finally going to some train station where a final clue was hidden. After that, we, the people who solved the puzzle (5 or 6 iirc) were invited to the AIVD offices for a chat with the authors and a bit of PR and a tour through the museum (during which the big boss offered jobs (whispering) to a few of us). I was impressed by their skills, never expected that from government people really.
