New fancy shit that people use to cheat into pro play functions via intercepting and altering mouse input without running programs on the OS, doesn’t even need to mess with RAM. The one’s that do are way more common (dont intercept mouse traffic, but are still largely undetectable) because they’re running scripts that emulate a 2nd mouse.
Typical purchased hardware aimbot though runs DMA scripts off the RAM ( not even just aimbot, also works for maphacks) that people have been banned for but that’s because they used an open source cheat without changing the hardware IDs, so anticheat just runs checks for these hardware ids and banned the player ingame. I don’t think anyone who actually changes the hardware IDs has been banned yet for DMA, it’s completely unviable to detect either of these and even handcam players have gotten away with it on Twitch up until a manual inspection of their mouse inputs.
We’re in an age where you can load a 3rd party maphack off your smartphone with just some expensive hardware for your PCIe slot.
