Hacker Tactic: Internal ESD Diode Probing

Humans are walking high voltage generators, due to all the friction with our surroundings, wide variety of synthetic clothes, and the overall everpresent static charges. Our electronics are sensitive to ESD, and often they’re sensitive in a way most infuriating – causing spurious errors and lockups. Is there a wacky error in your design that will repeat in the next batch, or did you just accidentally zap a GPIO? You wouldn’t known until you meticulously check the design, or maybe it’s possible for you to grab another board.
