dlang: "they can also modify anything else in your kernel, so why would they go to the trouble of targeting a specific piece of hardware when they can do it all from the common x86 compatible cpu" To make malware resistant to software reinstall on hardware with some reprogrammable memory. If firmware malware works badly, it makes normal administrator to trash the hardware. If firmware malware works fine, it sits there for long and being resistant to many current and common schemes to prevent and detect malware. Not many of us do reflash hardware, which have worked fine. At least it goes quite far away from current threat models. I think the scope of target doesn't have to be limited to specific hardware, but to cracking software, which can be run once on a compromised system. The software could know more hardware.
