They call that out specifically at the end, CPUs with their own embedded TPM aren't vulnerable to this kind of attack as all the communication occurs within the CPU itself.
- Dylan16807 3y agoLet me rephrase. I know this attack doesn't apply to commonplace embedded TPMs. I think the label of "security theater" doesn't apply to commonplace embedded TPMs.
- GauntletWizard 3y ago"embedded TPMs" are not commonplace. Intel has been pushing this hardest, and Intel still includes the TPM on the motherboard chipset and not the CPU itself in all consumer models, as of the 13th gen, at least.
- fomine3 3y agoIntel PTT is now quite common, isn't it?
- GauntletWizard 3y agoPTT is in the southbridge - That is, not the chip but motherboard chipset.
- nullindividual 3y agoSouthbridge was eliminated years ago. Intel PTT is present on the Intel PCH located on the processor die package, not a chip on the motherboard.
- Dylan16807 3y agoIsn't that only for laptop packages? I can find lots of current motherboards with a chipset on them, even specifically calling it a PCH.
- nullindividual 3y agoYep, you're correct. I misread. The Northbridge has been eliminated entirely. PCH is separate.
- Sakos 3y agoDon't Zen 2-4 all have fTPM?
