Putting Our Hooks Into Windows

This report explains how an attacker can use the Windows SetWindowsHookEx API to register a keyboard hook that causes a malicious DLL to be loaded into other processes and capture keystrokes; it includes C and C# example code, a sample DLL that triggers on a specific key sequence, and notes on reversing the compiled binaries. The write-up highlights capabilities (keystroke logging, DLL injection, persistence patterns), limitations (only affects processes owned by the current user) and detection considerations.
