Many of the exploits are buffer overflows, but The Tweezer Attack was fascinating. First to glitch the system with metal tweezers and then to dump the RAM via a makeshift serial port cobbled into the controller port. I get that the shorting of the pins might have been discovered by reading a spec sheet. How the serial port was made and enabled to dump the RAM is just awesome. There has got to be more to this part of the story not covered here.
