Not just a root kit, "Back Orifice 2000 is the most powerful network administration tool available for the Microsoft environment, bar none" ( It can be used to break a Windows system's (lack of) security (cars can be used to run over people too), but that isn't its main purpose; it's just a really good remote control package under the GNU General Public License.

Actually, BO2K is not that much different from other Windows remote control software such as CoSession Remote, Symantec's pcAnywhere, or Compaq's Carbon Copy, except pcAnywhere costs $169 and is not free software, whereas BO2K is under GNU GPL and takes eight times less RAM and 20 times less storage. A list of BO2K's features with respect to other remote control software can be found at

Back Orifice 2000. Show some control.

Remote administration software for windows by a group called CULT OF THE DEAD COW. Also known as BO2K. The original version was just called back orifice. Major differences between this version and the original are strong encryption through plugins, and the ability to use TCP.

Back Orifice 2000 is a back door program that lets you remotely control a computer running Windows through TCP/IP. Although it could be used for legitimate purposes, it is most often used for cracking. When connected to a BO2K server, a BO2K client can download files, upload files, delete files, edit the system registry, make dialog boxes pop up, reboot the computer, and many other things. Many useful plugins have been written for BO2K, including several good encryption plugins, a few that send an email containing the IP address of the BO2K server when the computer with the server on it connects to the internet, and one that will let you see a video stream of the server's screen, among many others. There is also a very useful program that combines a BO2K server program with another Windows executable, allowing people to disguise the server as a legitimate program that does something (instead of the normal BO2K server installation program, which appears to do nothing but delete itself). BO2K can be annoying however, when the l33t script kiddies use it as their reason for being "hackers". BTW, the default port for BO2K is 31337.
