> attach malicious devices to the PCI bus to DMA sensitive data

How do you do this in modern system with TPMs and IOMMU enabled?

Sadly not all Windows machines are able to use kernel DMA protection, so for those machines nothing will stop you.

  • The obvious next step is to disallow those elderly machines once a critical mass of users have modern-enough equipment. We're almost there.

You pretend to be a device with a driver not compatible with IOMMU

  • This is a good move, but why isn't the anti-cheat software just refusing to operate on systems with these devices attached?
