Technical Details

A backdoor is a remote administration utility that allows a user to access and control a computer, usually remotely over a network or the Internet.

These utilities may be legitimate, and may be used for legitimate reasons by authorized administrators, but they are also frequently used by attackers to gain control of a user's machine without their knowledge or authorization.


Attackers can distribute a backdoor to potential victims in numerous ways - for example, as part of the payload for a worm or trojan; as a disguised file attached to a spam email; as a file shared on peer-to-peer (P2P) networks, and so on.

Attackers typically rely on either social engineering or exploiting a vulnerability to install the backdoor on a computer.

A backdoor is usually able to gain control of a system because it exploits undocumented processes or features in an operating system or installed program. Depending on how sophisticated a backdoor program is, it can perform actions such as:

  • Sending and receiving files
  • Browsing through the hard drives and network drives
  • Getting system information
  • Taking screenshots
  • Changing the date/time and settings
  • Playing tricks like opening and closing the DVD drive
