While I understand the utility behind "smart" cables, including updatable firmware, this makes me uncomfortable concerning "evil maid" attacks. Now we have to watch out anytime we plug anything into our machines. Apple has done a good job at remediating this sort of attack vector, but this seems like a security nightmare for those living in PC land. I recently mentioned that MSI shipped
300 models of motherboards with Secure Boot disabled for over 18 months. If major companies can't handle simple security measures like that, then I don't see this working out well.
These days, any USB drive that isn't personally vetted is automatically suspect. What next, our toaster ovens will need firmware updates?
Oh wait.
