this one in particular is hard for them to detect without them monitoring what youre running in the backround as well much more intrusive than the current anti cheat . this exploit in particular is an image scan hack , meaning its an external application that is scanning your gpu ' s output to your monitor for certain things that it determines are a marker for an enemy , and then emulates mouse movement to get your crosshair onto the target . currently blizzards anticheat only detects programs that interact with the game directly memory hookrewrite based hacks for example , and for them to be observing everything else that goes on in the backround of your pc while running battlenet or overwatch could be considered an invasion of privacy by a lot of people . long story short , this shits gonna be ugly until blizz updates OW ' s TOS to allow them to be more invasive
