NetBus or Netbus is a software program for remotely controlling a Microsoft Windows computer system over a network. It was created in 1998 and has been very controversial for its potential of being used as a backdoor.
NetBus was written in Delphi by Carl-Fredrik Neikter, a Swedish programmer in March 1998. It was in wide circulation before Back Orifice was released, in August 1998. The author claimed that the program was meant to be used for pranks, not for illegally breaking into computer systems. Translated from Swedish, the name means "NetPrank".
There are two components to the client–server architecture. The server must be installed and run on the computer that should be remotely controlled. You can download the setup-file of "NetBus 2.01 Pro" from this server. It was an .exe file with a file size of almost 500 KB. The name and icon varied a lot from version to version. Common names were "Patch.exe" and "SysEdit.exe". When started for the first time, the server would install itself on the host computer, including modifying the Windows registry so that it starts automatically on each system startup. The server is a faceless process listening for connections on port 12345 (in some versions, the port number can be adjusted). Port 12346 is used for some tasks, as well as port 20034.
The client was a separate program presenting a graphical user interface that allowed the user to perform a number of activities on the remote computer. Examples of its capabilities:
- Keystroke logging
- Keystroke injection
- Screen captures
- Program launching
- File browsing
- Shutting down the system
- Opening / closing CD-tray
- Tunneling protocol (NetBus connections through a number of systems.)
The NetBus client was designed to support the following operating system versions:
