Why not? You can't hide microcode or MEMS IMU elements or analog circuitry in a way that decapping and examination by experts cannot uncover. This very article shows acid etching the epoxy packages to inspect the die. There are experts like Ken Shirriff (kens on HN) who reverse engineer silicon devices at the transistor level.
How do you arrive at the conclusion that microcode or software cannot be detected even by experts?
- WClayFerguson 6y agoSure given enough time to study chips and microcode it can be reverse engineered. Despite my degree in M.E. I've been a software developer for 30 yrs. :) So I know you're right. I was just saying it's a practical impossibility for even an electronics expert and even after disassembling something, to detect if a device had been recording or not, just by examining the device physically. Once you start reverse engineering the code itself you're likely to find any hidden surveillance, but even then not guaranteed, because sufficiently obfuscated code can camouflage what it's true purpose was.
