my anticheat idea

the first step to the disconnection is using a widget to create a button that tracks mouse movement once the mouse is locked.
again the widget being held on the same hdd is vulnerable though. its accessible to tampering itself. so the widget would have to held outside of the hdd maybe on the game server and uploaded to the player pc randomly and the test for mouse movement when the anticheat prevents mouse movement triggers the hackers lack of anticheat means his mouse still moves.
this might take some trial and error to find a cheater and then test what hes turned off because they keep the anticheat running its just not functional.
