> Once hardware begins to turn against you, there seems to be nothing anyone can do to protect themselves. Encryption doesn't work against an adversary that has access to your computer's memory.
In the future (or today, depending on your setup), IOMMU. In the present, there is no evidence that baseband backdoors of this type actually exist (as opposed to hacks). When the adversary adds backdoors deeper in the hardware? ...well, we'll see if that is discovered someday.
To editorialize a bit, I guess it can't hurt to worry about and try to head off anticipated future threats - it's not like anticipating different threats is mutually exclusive - but still, I somehow can't shake the feeling that people's emphasis on secret backdoors unduly weights threats that are easier to romanticize over more pragmatic but more dangerous ones.
