Reflective PE Unloader
- This is code that can be used within a PE file to allow it to reflectively reconstruct itself in memory at runtime. The result is a byte for byte copy of the original PE file. This can be combined with Reflective DLL Injection to allow code to reconstruct itself after being loaded through an arbitrary means.

Dynamic Link Libraries

DLLs are Win32 libraries, loaded and linked at runtime (hence the name), built on top of the Portable Executable format. DLLs and EXEs differ by basically one byte in the PE file format, indicating whether this is executable (and therefore has a main()-style entry point) or not.
