This should be modded up higher. Exactly. The only way hackers found this is because they weren’t using secure boot or encrypted images. Every embedded developer knows about MCUboot. Except managers don’t want the overhead because it is complicated. Once embedded devs get the ok all embedded firmware will basically be like a Signal chat with only the manufacturer having the keys. Heck even PSA compliant hardware MUST be resistant to multibit glitch attacks. Bye bye hackers.
