Windows reverse Shell

Hello guys,

David Litchfield in his Blackhat talk, talked about using socket handle from WSASocket() and pass that handle as a parameter to stdin, stdout and stderr for CreateProcess function. By doin this way his reverse cmd shellcode becomes much smaller. I tried coding that reverse command shell in C, but couldnt get it to work. It simply connects to my listening netcat listener and then disconnects. David Litchfield used 4 functions to achieva that WSASocket, bind, connect and CreateProcess. A lil help would b appreciated on building this reverse cmd shell. thanx.
