Ghost

ghost is a light RAT that gives the server/attacker full remote access to the user's command-line interpreter (cmd.exe). They are allowed to execute commands silently without the client/zombie noticing. The server/attacker is also given the ability to download and execute files on the client/zombie's computer. This is also a silent and hidden process. Like most Remote Access Trojans, this download and execution ability helps distribute viruses and other pieces of malware.
