Re: Seems like Rube Goldberg approach to spying

Not so: if (as another poster has described) you have an SPI memory with a "secret" bank and a regular one, and the sneak chip flips between the two, why would you not also have it treat the JTAG interface in a similar sneaky fashion (i.e. write the new code to another bank)?

Remember: the implication is that these are custom designed parts to do the job, not commodity parts being used to carry malware.
