In more ways than you&#x27;d know. They&#x27;re already pre-backdoored like almost all other chips for debugging purposes in what&#x27;s called Design for Test or scan chains or scan probes or something. Much hardware hacking involves getting to those suckers to see what chip is doing.<p>Now, for remote attacks, you can embed RF circuitry in them that listens to any of that. You can embed circuits that receive incoming command, then dump its SRAM contents. You might modify the I&#x2F;O circuitry to recognize a trapdoor command that runs incoming data as privileged instructions. You can put a microcontroller in there connected to PCI to do the same for host PC attacks. I know, that would be first option but I was having too much fun with RTL and transistor level. :)
