Not sure if it would work, but wouldn't it greatly complicate creating a backdoor when the host's memory is very heavily constrainted? e.g. an AVR-based "computer" that would hardly do much more than actually translate assembly to machine code?
- kragen 4y agoIt would probably be easier to detect, but when Thompson deployed the attack in practice, nobody noticed, even though the PDP-11 address space was the same size as an AVR's, and the CPU was a lot slower. (AVRs invariably have much less physical RAM installed than a PDP-11, but you'd need some external memory to get a C compiler to build.)
