Valve announced a change for Steam today that will make things a lot clearer for everyone, as developers will now need to clearly list the kernel-level anti-cheat used on Steam store pages.

Developers will be required to disclose if their game uses kernel anti-cheat. This applies to both new games and existing games. Non-kernel anti-cheat is encouraged to be disclosed as well, but it’s only mandatory for developers to declare if they’re using kernel anti-cheat for the time being.

It’s worth mentioning that many games use kernel anti-cheat on windows, but only use user space anti-cheat on Steam Deck and Linux.

    It’s horrifying to me that any of these fucking games are running outside userspace. Is anti cheat the only reason why that is necessary? Why is it necessary for anti cheat?

      Running in the kernel let’s anti-cheat see everything on your computer, let’s devs take screenshots or videos of your screen, and let’s the anti-cheat reinstall itself if the user tries to remove it. It also lets the developers secretly install additional software if needed for some reason. Overall it’s pretty effective at being able to catch user space cheat programs, the catch is that you’re permanently compromising the security and privacy of your computer, and nothing short of a full disk purge will guarantee it’s actually been uninstalled.

      The other catch is it’s can still be defeated by kernel-level cheat programs, which are now widely available thanks to the rise of kernel anti-cheat. It also can’t do anything about cheat programs that run on external hardware, such as aimbots that just look at your video feed and simulate mouse inputs to aim.

      So it really comes down to how bothered you are by cheaters in your games, and if you’re willing to give up your privacy and security to make it slightly more inconvenient for those cheaters to cheat.

        I should probably mention some notable downsides to kernel anti-cheat as well:

        • Because kernel anti-cheat has full access to your PC, if any virus/etc can take advantage of a security vulnerability in the anti-cheat program, it gains absolute access to your PC.

        • Kernel anti-cheat needs special signing keys to get access to the kernel, but the more companies that get access to the keys the more likely it is to have compromised keys. Genshin impacts keys were compromised and used to sign ransomware, giving it full kernel access on any computers it was able to get on.

        • Devs have used kernel anti-cheat to secretly install Bitcoin miners on users machines

        • Kernel anti-cheat can be compromised and used to directly gain control of a users PC. Some apex legends streamers had their PCs compromised and cheats installed remotely through their anti-cheat during a tournament.

        • A lot of anti-cheat programs are created by Chinese companies or companies that are mostly owned by Chinese companies. China is well known for spying on users, and there’s a ban on a lot of Chinese hardware due to spying concerns and backdoors that the Chinese government requires to be in their devices. I think the invasive nature of kernel anti-cheat makes it an obvious spying platform, and I think it’s absurd to think that any anti-cheat coming from China isn’t actively spying on you.

          Our data has proven to be very lucrative. The companies that make anti-cheat are also the types of companies that would want to cash in on our data.

        The thing I think is left out is that it usually eliminates all of the casual cheaters. For many games this is a massive change in the feel and culture of the online space in the game.

        But yeah, no matter what, even when the games are never on our hardware and become just video streams sold to us by the hour, cheating tools will always exist. Even if it’s just a bit of tape on your monitor.
