Global Injection and Hooking Demo

A global injection and hooking example. Injects into all processes and hooks the MessageBoxW function. Also hooks the CreateProcessInternalW function to be able to inject into newly created processes. Refer to the blog post for details: Implementing Global Injection and Hooking in Windows.

• Go to Build -> Batch Build...
• Select the following three configurations, Configuration can be Debug or Release:
  • Project global-inject-demo, Platform Win32.
  • Project global-inject-lib, Platform Win32.
  • Project global-inject-lib, Platform x64.
• Click on Build.

Running

• Make sure you have the following files in your execution folder:
  • global-inject-demo.exe
  • 32\global-inject-lib.dll
  • 64\global-inject-lib.dll
• Run global-inject-demo.exe to load the library in all processes.
• Close the window to unload the library from all processes.

Seeing it in action

Use any program that displays a message box using the MessageBoxW WinAPI function. An easy option is running slmgr.vbs via the Run dialog (Win+R).
