The chip doesn't need networking, it needs to infect existing firmware with networking. The motherboard/nic firmwares already have that. Nor would it necessarily be limited to the IPMI side nic as they imply. Steganography could be used to get through firewalls on net facing NICs. The part about "most sensitive code" wrongly assumes that means on storage devices and not motherboard firmware. As for the size, there are no commercial lithography methods with that capability, perhaps. It'd be possible to put significant capacitance and logic in a very tiny package with advanced lithographic techniques, say like gates printed into layers of a small cap? Yeah I'm getting really out there, but to say there's nothing so interesting in the highly compartmentalized world of spy tech is to make a claim in ignorance, naturally. Unless you're in a position to say precisely what technology they have, in which case, please contact me privately, since I'm curious. ;)
