A lightweight native DLL mapping library that supports mapping directly from memory

• WOW64 and x64 support
• Imports and delay imports are resolved
• Relocations are performed
• Sections are mapped with the correct memory protection
• Headers are mapped with the correct memory protection
• Exception handling is setup for both SEH and C++ exceptions
• Security cookie is initialised
• Entry point and TLS callbacks are called with ProcessAttach and ProcessDetach

• Install the latest stable version of Lunar using the GitHub Package Registry

The example below demonstrates a basic implementation of the library

var libraryMapper = new LibraryMapper(process, dllBytes);

// Map the DLL into the process

libraryMapper.MapLibrary();

// Unmap the DLL from the process

libraryMapper.UnmapLibrary();

LibraryMapper(Process, Memory<byte>)

Provides the functionality to map a DLL from memory into a remote process

LibraryMapper(Process, string)

Provides the functionality to map a DLL from disk into a remote process

DllBaseAddress

The base address of the DLL in the remote process after it has been mapped

MapLibrary()

Maps the DLL into the remote process

UnmapLibrary()

Unmaps the DLL from the remote process

• Attempting to inject into a system level process will require your program to be run in administrator mode
• Mapping requires the presence of a PDB for ntdll.dll, and, so, the library will automatically download the latest version of this PDB from the Microsoft symbol server and cache it in %temp%/Lunar/PDB
