Microsoft has enforced mandatory digital signatures for drivers, and getting a digital signing key from Microsoft costs a ton of money. So, presumably they do care.
In contrast, consider nProtect GameGuard, the anti-cheat system in Helldivers 2. It is a rootkit, and runs in the kernel. Why does Microsoft permit this? Shouldn't this be blocked? It must be using either an exploit like the article, or a properly signed driver. Either way, Microsoft could fix it -- by patching the exploit, or revoking the signing key.
The fact that Microsoft hasn't done anything about malicious anticheat rootkits is a sign that they really don't care. They just want their payment.
I might be completely wrong, but I've heard that a key is only a few hundred dollars, and once you've got it you can sign whatever you want. I think ReactOS also used to offer free driver signing for open source projects.
So I guess if ReactOS can afford one, so can most anti-cheat companies.
I think what we're trying to say here is FUCK kernel-based anticheat systems!
