Lunar

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

---

Features

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

---

Installation

• Install the latest version of Lunar using NuGet

---

Getting started

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();

---

Constructors

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

---

Properties

DllBaseAddress

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

---

Methods

MapLibrary()

Maps the DLL into the remote process

UnmapLibrary()

Unmaps the DLL from the remote process

---

Caveats

• 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, will automatically download the latest version of this PDB from the Microsoft symbol server and cache it in %temp%/Lunar/PDB
