There is a Swedish proverb, “All methods are good except for the bad ones” which applies very well to reverse engineering. Sometimes targets elude the usual methodologies of reverse engineering and the need for alternative ways to the goal arises. This lightning talk is a sample of war stories from the fields (or playgrounds) of picking apart and understanding systems. The targets give rise to methods ranging from unusual to plain silly and shows that with determination and some creativity, even the most strange of challenges can be mastered. It will feature reverse engineering hardware curcuits as well as compilers created for the sole purpose of messing with people foolish enough to try to reverse engineer it and possibly some strange architecture or two.
