This is an injector abusing the implementation of certain features in Windows operating system to make your dll / injection hard to detect by anti-cheats. It will map your image in a special way that makes the memory pages invisible to Windows APIs, not debuggable from user-mode and execute it without creating or interfering with execution of a thread.
Not supported:
- KVA Shadowing
- Wow64
- SEH / VEH ( and it cannot be either as this memory region does not seem like a valid one to Windows )
- TLS
- Import mapping
- Any other cancerous PE details
