Why is kernel-level anti-cheat even a thing?
If I was trying to prevent cheating, I'd hash the relevant game files, encrypt the values, and hard-code them into the executable. Then when the game is launched, calculated the hash of the existing files and compare to the saved values.
What is gained by running anti-cheat in kernel mode? I only play single-player games, so I assume I'm missing something.
Modern cheats for multiplayer games don't modify local files (or attribute values in memory), since the server validates everything anyway. They're about giving you information that's available but not shown in the game (like see-through walls, or exact skill ranges), or manipulate input (dodge enemy damage, easy combos). Those cheat can run in kernel mode (or at least evade detection from user mode), so the anti-cheat needs kernel mode to be more effective.
They can prevent you from running cheats that other anti-cheats can't detect. For instance, they could modify the value in memory so that your calculated hash always succeeds even when it's modified. This doesn't stop cheating though; it just means cheaters have to use cheat hardware that exists at a layer that even kernel anti-cheat can't detect.
You don't need to modify the files to modify data in memory.
I wish Valve would just ban them. It's weird to have something that looks like pure malware in a Game store.
Probably a pessimistic take, but I don't expect this to have any discernable impact on sales, or any other effects that would discourage publishers from these practices. The average user doesn't care about or understand how these things work; they'll see an anti-cheat warning on the store page and think "Okay, tell the colonel I'll be on my best behavior then" and continue to buy the game.
It will benefit those that care and won't negatively impact the experience for those that don't.
Win, win.
Not to be annoying, but can someone please ELI5 how kernel level anti-cheat software actually works, or link good resources where I can read about it.
It runs with higher priveleges than you have and can see anything that happens on your computer.
It also creates a giant additional attack vector.
Eli5: your PC has different access levels a program can run at. This prevents a malicious or badly coded program from completely fucking your computer. Kernel level anti cheat runs at the lowest level access that exists under windows. It can do basically whatever it wants to your PC, and if a backdoor is coded in (happens way more than you'd think), it gives malware basically total access to your PC.
