You can buy an autoclicking device or software that recognizes screen pixels of enemy avatars and instantly clicks to kill them. This works in "remote streaming" situations and is ~30% of the cheating dataset detected by Riot's kernel level anticheat:

> A “pixelbot” is a computer vision cheat that injects player input for the purposes of aiming at heads or casting spells with perfect timing. Coming in “external” (hardware microcontroller) and “internal” (python script) varieties, pixelbots can be extremely impactful in VALORANT due to the low time-to-kill, sometimes just simply pulling the trigger for the cheater when an enemy enters their reticle (also known as a “triggerbot”).

This isn't possible in Valorant. Their kernel module is extremely particular about input devices:

1) only allows a single mouse input device at a time

2) completely ignores virtual mouse input

3) flags "special"/"uncommon" input devices

Their anti-cheat is actually much more involved and effective than most would assume.

Websites that sell DMA devices also sell devices that merge mouse usb and hdmi signals that allows you to run the cheat on another machine and let it display en ESP overlay and do aimbot. It's likely that a naive implementation of such an usb device would be detected. But can you create such a device that uses a normal mouse usb driver and looks like a normal mouse?

		At least in Valorant, DMA is becoming impossible due to IOMMU / Memory Integrity enforcement. The only option is becoming pixel bots. As for faking the input device: I'm sure it's possible, but I'm also sure that perfectly spoofing an input device is much easier said than done. Even if it is possible, all they have to do is make it hard enough to where the percentage of players cheating is at the point where you will rarely if ever encounter a cheater in your matches. As far as I'm aware, Valorant is one of the only games that has accomplished that.

But really, if HID becomes suspect too, then why do you even need kernel level anti-cheat, if all you can do is behavioral detection?

If you're in the kernel you at least have raw access to the USB controller and input events, thus can try pick out real mouses from fake ones.

		If the point of those events is to be registered by the game program, you already have all the data you need, otherwise you're building a keylogger. The most the kernel can try to tell you is what's plugged in, but the cheater can easily make the fake HID interposed between the real keyboard and USB.
