I read an article about the early DirecTV hacking days and the cat and mouse game the hackers played with the company. DirecT cards were smart cards that ran programs for the decryption path. The hackers kept just duplicating whatever DirecTV sent down to keep them workign, mystery bits and all. Then one day a final update came out and those weird bits turned out to be a specially designed program that bricked all of the hacked cards. I'm sure that was a temporary setback for the hackers but it was a great story.
