AntiDe4dot
How it works?
Protection adds multiple attributes of known obfuscators/protectors and as a result fools de4dot.
Protection Type
The protection type is Protection.
Warning
Due to protection is not really powerful and widely known by most reversers and skids, on GitHub you may see a lot of solutions to destroy this protection.
IL2CPP
Not supported on IL2CPP builds. It injects decoy obfuscator-marker types whose names aren’t valid identifiers, and only confuses managed-PE tools (de4dot) that never see the IL2CPP build. BitMono skips it automatically when building for IL2CPP (see Unity Protections).
