'''Back Orifice 2000''' (often shortened to '''BO2k''') is a [[computer program]] designed for [[remote administration|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.

BO2k debuted on July 10, 1999, at [[DEF CON]] 7, a computer security convention in Las Vegas, Nevada. It was originally written by [[Dildog]], a member of US hacker group [[Cult of the Dead Cow]]. It was a successor to the cDc's [[Back Orifice]] remote administration tool, released the previous year. {{As of|2007}}, BO2k was being actively developed.

Whereas the original Back Orifice was limited to the [[Windows 95]] and [[Windows 98]] operating systems, BO2k also supports [[Windows NT]], [[Windows 2000]] and [[Windows XP]]. Some BO2k client functionality has also been implemented for [[Linux kernel|Linux]] systems. In addition, BO2k was released as [[free software]], which allows one to [[porting|port]] it to other operating systems.
