This year’s annual DEFCON computer security conference was as usual attended by the smartest computer people in the world. The hackable convention badges were custom printed circuit boards complete with a microprocessor. The board also contained a Datamatrix code which decoded to a cryptic image on the DEFCON website. Nobody seems to be able to decrypt the message but the consensus is that the symbols and numbers may be part of an online scavenger hunt. (Thanks to Kevin Lim for the picture and a very interesting website).
If you have any ideas on what this image means, let me know!
