Inject-Hook-Unhook_POC

POC demonstrating DLL Injection, API Hooking and API Unhooking.

How to use

1. Compile code in all the folders, i.e., "Use Simple DLL", "Simple DLL", "Inject Me Hook Me"

2. First run "Inject Me Hook Me.exe" and wait for first message box

3. Next run "Use Simple DLL.exe" with arguments as path to "Simple DLL.dll" and the PID of "Inject Me Hook Me.exe"

What's happening here?

The DLL is injected into the mentioned process and the MessageBoxW API is hooked. The process then unhooks the hooked API on the second attempt of running the hooked function.
