> Hmm, I’m not sure I agree. Malicious firmware blobs in your disk controller could do all sorts of damage, like silently replacing parts of executable files with whatever they like. Someone made a proof of concept of this a few years ago - where they managed to replace some of the controller firmware in a hard disk. Their modified drive would then silently replace a certain executable with something else. And on that drive, the attack was persistent. See Spritesmods.com [1] for a PoC from 2013 (!!). Guy managed to run Linux on the firmware. [1] http://spritesmods.com/?art=hddhack http://spritesmods.com/?art=hddhack
