EasyAntiCheat Anti-Debugger

Does anyone have any clue how EAC detects it's in a debugger (both user and kernel debuggers)? Also I have no idea how Rust.exe gets a handle on the EasyAntiCheat device, there's no "\\Device\\EasyAntiCheat" string in either Rust.exe or EasyAntiCheat_x86.dll and I've checked all the calls to CreateFile in both. I couldn't find anything. Any help would be appreciated.

🧬 1. Signature Scanning (Like a Virus Scanner)
EAC compares files and memory chunks to a database of known cheats.

If it finds matching code patterns (like cheat DLLs or trainers), you're flagged.

Example: A popular aimbot gets detected because its code hasn’t changed.

🧠 2. Behavior Analysis
It watches what the player is doing in-game.

Unrealistic aim, perfect timing, or impossible movements? That raises red flags.

Example: Hitting 100% headshots through walls looks sus — even without known cheat files.

🧪 3. Memory Scanning
EAC checks the game’s memory in real time.

If it detects tampering (like an injector modifying ammo or health values), it can block or ban.

Example: A cheat tries to freeze health at 100 — EAC spots the memory value being locked.

🧰 4. Kernel-Level Checks
Some cheats operate at a deep system level (kernel).

EAC also runs kernel-level components to detect hidden drivers and tools.

Example: A rootkit cheat tries to hide itself from the system — EAC sees it anyway.

🔒 5. File Integrity + Anti-Debugging
It checks if game files have been changed or if someone is running debuggers (tools to analyze or change code).

Example: Someone edits a config file to unlock dev options — EAC sees the mismatch.
