The vanguard drivers are signed by Microsoft, the procedure for which includes a safety audit by Microsoft.
The driver is just what the developers say it is (as with all other anti-cheat). It provides an untempered interface for the userland anti-cheat to use to get info from the kernel. Because modern cheats tend to alter the output of kernel syscalls by running in the kernel themselves.
I really don't see why anyone needs to think it's anything more than that.
If Tencent needed to spy on you so badly there's no reason kernel anti-cheats need anything to do with it...
It says something about Microsoft when they OK a known harmful bootkit that expects your computer to act like an XBox with a fancy keyboard (but not too fancy), requests invasive changes to UEFI that have broken systems, and have an overall opacity that rivals an Arthur C. Clarke Monolith.
Drivers are generally not audited by Microsoft to be signed, you only need to register your EV cert to get it signed. Cheat developers have registered their own/gotten their hands on EV certificates to create a kernel driver cheats. Anti cheat like Battleeye also download anti cheat modules at runtime to obfuscate what they do.
MS usually don't bother with driver audit... They mostly rely on EV certificate to check driver dev is a proper legal entity.
If they audit properly, they should not let the Asus AuraSync driver certified at the first time. (basically opens PORT instruction to every userland app, unristricted)
The level of sophistication that can go into a hack when sponsored by a nation-state is incredible. Just remember Stuxnet all the way back in '06 or whatever it was. Tech was a lot less advanced nearly two decades ago. It's not right, imo, to leave your safety up to this process.
EAC and other kernel-level anticheat software will dynamically load and execute signed payloads at runtime. Does Vanguard do this? If so, does Microsoft check these payloads?
