This is this is similar to all the backdoored Cisco devices the FBI found all over the government. If they are doing it at all they would have a complex plan and this would be one of the many approaches. Even scarier IMHO are the CPU fabrication hacks that add in an imperceptible backdoor directly in the chip logic. A recent report showed how CPUs can be backdoored at critical points in the fabrication process by a single operator that would be incredibly hard to detect. We are talking instruction patterns that charge capacitor buffers that allow privileged access once a threshold is reached. Amazing really.
