How Anti-Cheat Systems Detect Cheats: EAC, BattlEye, and Vanguard Explained

The Battle for the Kernel

Modern anti-cheats like Vanguard, Easy Anti-Cheat (EAC), and BattlEye operate at the highest privilege level of your OS: Kernel Mode (Ring 0). This gives them the same level of access as your system drivers.

Common Detection Methods

1. Signature Scanning: Anti-cheats maintain a database of "fingerprints" for known cheat software. If they find a match in your memory or on your disk, you're banned.
2. Heuristic Analysis: They look for suspicious behavior, such as a process reading the memory of a game client or a sudden, non-human mouse movement.
3. Heartbeat Checks: The game client sends regular "I'm clean" signals to the server. If these stop, the server assumes you've tampered with the game.

Why External is the Solution

By running externally, Soapimane avoids injecting code into the game process, bypassing many of the common checks performed by signature scanners.
