Context

Back Orifice 2000 (often shortened to BO2k) is a computer program designed for remote system administration. It enables a user to control a computer running the Microsoft Windows operating system from a remote location. The name is a pun on Microsoft BackOffice Server software. Back Orifice 2000 is a new version of the famous Back Orifice backdoor trojan (hacker's remote access tool). It was created by the Cult of Dead Cow hackers group in July 1999. Originally the BO2K was released as a source code and utilities package on a CD-ROM. There are reports that some files on that CD-ROM were infected with CIH virus, so the people who got that CD might get infected and spread not only the compiled backdoor, but also the CIH virus.
