Sub7 is a trojan (or as its users like to call it "Remote Administration Tool") in the line of back orifice and netbus. It has the power of back orifice, the user-friendliness of netbus and the features of both.The program allows one to gain remote access to another computer if the other computer has a server running. The catch is that the victims do not know that the Sub7 servers running on their box. Once connected users can access files and change settings on the other computer as if it was their own. Their are also some fun extras such as the ability to log all keys typed, get screen captures, kill apps, etc.
