    Not super practical, but neat attack

      That is peanuts for a nation-state actor.

        Sure, but if you’re defending against a nation state actor hopefully you aren’t expecting a raspberry pi to keep you secure.

          Is there anything about these techniques that are raspberry pi specific? It seems like they're using lasers to identify and flip particular bits in registers.
