Yeah, the moral of the story is if you see someone you don’t know with a dewar of LN2 and a screwdriver hanging around your computer, you should become suspicious...
I think the rest of the moral is that the people who spent time figuring out that if you yank out a chip, within .73 seconds dip it in liquid nitrogen, 43 seconds later install it in a new machine, run some specialized software, you MIGHT be able to unencrypt something.
These folks need jobs.
Real jobs.
