Shellcode reflective DLL injection in C++

Reflective DLL injection demo for fun and education. In practical applications, there's significant scope for enhancing build sizes, obfuscation, and delivery logic.

A blog post describing the technicalities of sRDI.

Project Structure

.
├── build.sh            # Build script (cmake & make)
├── generator           # Shellcode generator (ties together bootstrap, loader, payload, and user data)
├── injector            # PoC injector
├── payload             # PoC payload (DllMain & PrintMessage(lpUserData))
├── reflective_loader   # sRDI implementation
├── shared              # Common cryptographic & file modules
└── toolchains          # Cross-compilation toolchains (linux & darwin)

Features

  • Hashed import names & indirect function calls
  • Randomized export iteration & IAT patching
  • XOR encryption for shellcode (randomized key generated during shellcode generation)

Check out Alcatraz for additional obfuscation for the shellcode/injector.

Usage

Compile the libraries and executables with the included build.sh shellscript (if cross-compiling).
