"third party anti-cheat kernel driver" should strike the same kind of fear in you as "debug port left exposed" or "default root telnet password"
there should be no business sense for MS to sign these; they should not be signed, signing them should result in fines and sanctions, and the OS already doesn't load unsigned kernel drivers.
this shit should, honestly, be illegal through and through.
I can only imagine how much restraint it took to wait for this tournament while knowing you have this and it could possibly get patched at some point, either you end up with nothing or you get the funniest possible way to show off a hack
edit: you're wasting your time asking for security advice for software I don't use, I can't help you
like they could have easily just installed crypto miners on a bunch of random people's PCs instead of doing this so I'm glad it was this
