Back orifice

Updated: 09/15/2017 by Computer Hope

Sometimes abbreviated as BO, back orifice is a trojan horse program created by the hacker group Cult of the Dead Cow that allows full access to the computer its installed onto. Therefore, a malicious user could delete files, change files, copy files, or edit system settings. He or she would essentially be able to do anything to a system remotely without most users being aware. To be infected with back orifice, an executable file that secretly places the file on the computer must run on the computer.

To determine if back orifice is present on a Windows computer open the Windows command line and run the following netstat command. If an up-to-date antivirus program is installed, it should also be capable of detecting back orifice.

netstat -a

If a local address has a port of 31337, it is likely that back orifice is present on your computer.


Computer Hope will not supply any user with BO or any utility that provides illegal access to other computers.
