Back Orifice
es un programa de control remoto de ordenadores que funciona bajo un servidor y
un cliente. Si colocamos el servidor a otro ordenador remoto, es posible desde
el cliente, gobernar cualquier función del ordenador remoto, entre los que
destaca abrir y cerrar programas, controlar el CD, leer y modificar ficheros o
borrar parte del disco duro. Para ello el servidor se autoejecuta y se borra
cada vez que el ordenador ajeno se enciende, nuestro cliente escanea el puerto
elegido y cuando este esta abierto actúa a través de él, desde un menú repleto
de pestañas y opciones de control remoto. El sistema es bueno para controlar un
ordenador u ordenadores dentro de nuestra red LAN, aunque dejar este puerta
abierta para Windows es toda una amenaza.

Back Orifice (often
shortened to BO) is a controversial 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.
Although Back Orifice has
legitimate purposes, such as remote administration, there are other factors
that make it suited for less benign business. The server can hide itself from
cursory looks by users of the system. If wrapped inside a Trojan horse, it can
be installed without trouble and used as an attack point or just to spy on or
harass the unsuspecting user.
For those and other reasons,
the antivirus industry immediately categorized the tool as malware and appended
Back Orifice to their quarantine lists. Despite this fact, it was widely used
by script kiddies because of its simple UI and ease of installation.

A Trojan horse that installs
itself as a server on a machine, and allows a user with the BackOrifice client
to control the host remotely. Hackers often distribute seemingly harmless
executables that also install BackOfifice.
Once installed, a hacker can access all files, system passwords,
keystrokes, ad other confidential information to further compromise the
network.
