Dark Connection Inside, also known as Backdoor.DCI.12 and Dark Connection, is a backdoor Trojan affecting Microsoft Windows operating systems. The server attempts to open a port, typically TCP port 666, to allow the client system to connect. The client has the ability to emulate the server when it is running. This can be used to trick other hackers, and all commands sent to the emulated server are shown on the local client.
