Just released a new paper about Reflective Dll Injection.
Reflective DLL injection is a library injection technique in which the concept of reflective programming is employed to perform the loading of a library from memory into a host process. As such the library is responsible for loading itself by implementing a minimal Portable Executable (PE) file loader.

Support for Reflective DLL Injection has also been added to Metasploit in the form of a payload stage and a modified VNC DLL.
