BotScreen: Trust Everybody, but Cut the Aimbots Yourself

Aimbots, which assist players to kill opponents in FirstPerson Shooter (FPS) games, pose a significant threat to the game industry. Although there has been significant research effort to automatically detect aimbots, existing works suffer from either high server-side overhead or low detection accuracy. In this paper, we present a novel aimbot detection design and implementation that we refer to as BotScreen, which is a client-side aimbot detection solution for a popular FPS game, Counter-Strike: Global Offensive (CS:GO). BotScreen is the first in detecting aimbots in a distributed fashion, thereby minimizing the server-side overhead. It also leverages a novel deep learning model to precisely detect abnormal behaviors caused by using aimbots. We demonstrate the effectiveness of BotScreen in terms of both accuracy and performance on CS:GO. We make our tool as well as our dataset publicly available to support open science.
