      LOL this is wild - apparently the game cheating community have discovered DMA attacks are a good way to evade Anti-cheat https://www.unknowncheats.me/forum/anti-cheat-bypass/304545-detecting-dma-hardware-cheats-16.html … Secure boot, HVCI, and IOMMU policies with attestation would be a much better experience than all these AV-style drivers for AC imho.https://twitter.com/UlfFrisk/status/1362528488411066368 …

      I have a hard time understanding why game companies don't just incentivize good users to turn on more attestable security features that are useful for anti-cheat with the benefit of playing in lobbys with other users who have less risk of being cheaters.

      Most of the desktop motherboards popular among gamers are total garbage in terms of platform security, HVCI will not help if you don’t have Boot Guard and firmware level DMA attacks protection

      Also, HVCI will not help when there’s a lot of WHQL signed drivers which provides full access to the physical memory. Many of them are *already* installed on typical gaming setup as part of OEM utilities

      thats it- so many ways to do it, but that one is so easy its often used. but...who cares about whql? its only a requirement for pnp drivers....just load other way

      Replying to @jonasLyk @dwizzzleMSFT

      Well we are assuming that there’s VBS enabled desktop where HVCI prevents you from executing of random shit in the kernel mode and some sort of anti-cheat driver prevents you from touching of the game process from the user mode

      Replying to @d_olex @jonasLyk @dwizzzleMSFT

      ... in such scenario you can compromise HVCI by running DXE phase bootkit (even DMA delivered, as an option) OR by using WHQL signed driver for physical memory access. Second option is more easy to implement

      also a fine way- and you can even unload the driver after you mapped- but before game runs
