“Kernel” anticheat isn’t really any more dangerous than any other executable you run on Windows. Code from untrusted devs isn’t safe whether it has admin or not. Games made by small devs are much more dangerous than anything put out directly by Riot or Valve.

Remember when Sony automatically installed a rootkit on customers’ computers if they put in their legally purchased music CD to listen to, that was a security vulnerability that hackers quickly found and exploited? Pepperidge farm remembers.

Incompetence is just as dangerous as malice, and big companies have shown they don’t bother to take the care needed to protect your device.

I don’t think YOU understand how code works. Having a program that you can’t verify being run as the highest priority level in your system is a stupid idea. You don’t know how secure it is or if it has vulnerabilities because again, it’s not open source. They are not even security experts, they are a game development company (which will hire security experts, sure, but the main focus not being security is important) and riot is not know for having a super robust game.

Do you really trust them to release a program that can’t be hacked into, which then would give the hacker a way to elevate privileges into the highest security level? Even if you trust them not to harvest and sell private data, you have to also trust them to make an unhackable program.
