GrimAC
Fully async, multithreaded, predictive, open source, 3.01 reach
GrimAC is an open-source anticheat system designed to detect and prevent cheating on Minecraft multiplayer servers through predictive simulation and advanced movement analysis. The project uses a simulation-based detection engine that recreates player movement and physics in order to identify discrepancies between legitimate gameplay and modified client behavior. By analyzing how players move, interact with the world, and send network packets to the server, Grim can detect a variety of cheats such as reach hacks, speed hacks, and anti-knockback modifications. ...
