1) http://pastebin.com/i5v32fed (not made by me)

This sample uses the MS Detours Library (http://research.microsoft.com/en-us/projects/detours) to intercept windows socket API calls. Once inside the recv()/send() functions, you can let or block the packet being handled.

Important to remember that the target application may use socket functions from mswinsock.dll or winsock2.dll. So you may wanna check its Import Address Table (IAT) to see which DLL is being used.

2) On WinXP/9x you don't need a driver to hide the process from the user (Not sure if user mode hooks work on new Windows versions though)

Hope this helps!
