A plugin for Bukkit that detects exploits for various Flaws/Bugs in Minecraft.
AntiCheat will try to identify illegal data or packets sent by players that may be on your server and exploitation of bugs in the game based on the information or packets the player sends to the server. These cheats could range from going faster than you are supposed to in-game or have a farther reach distance than you are supposed to have. If any of this stuff is detected AntiCheat will stop them and enforce the regular boundarys.
AntiCheat will detect almost any exploit or cheat! The only thing that AntiCheat is incapable of completely detecting is Xray, but there are many other plugins than can help you with this issue.
