Persona que
se supone muerta y que ha sido reanimada por arte de brujería, con el fin de
dominar su voluntad.
DRAE. Diccionario
de la Lengua Española.
Es el nombre
que se da a los ordenadores que han sido infectados de manera remota por un
usuario malicioso con algún tipo de software que, al infiltrarse dentro del
propio ordenador manipulado y sin consentimiento del propio usuario, un tercero
puede hacer uso del mismo ejecutando actividades ilícitas a través de la Red.
Su uso más frecuente es el envío de comunicaciones electrónicas no deseadas,
así como la propagación de otros virus informáticos, conocidos así en el
lenguaje cotidiano, que constituyen uno de los grandes problemas de seguridad
informática.

Un ordenador
generalmente infectado con un troyano de acceso remoto, capaz de recibir

conocimiento de sus dueños.

(I) /slang/ An
Internet host computer that has been surreptitiously penetrated by an intruder
that installed malicious daemon software to cause the host to operate as an
accomplice in attacking other hosts, particularly in distributed attacks that
attempt denial of service through flooding. [RFC4949:2007]
A program that is
installed on a system to cause it to attack other systems. [NIST-SP800-83:2005]
A computer
attached to the Internet that has been compromised by a security cracker, a
computer virus, or a trojan horse. Generally, a compromised machine is only one
of many in a "botnet", and will be used to perform malicious tasks of
one sort or another under remote direction. Most owners of zombie computers are
unaware that their system is being used in this way. Because the vector tends
to be unconscious, these computers are metaphorically compared to a zombie.

In the West
Indies, a zombie is a will-less, automaton-like person who is said to have been
revived from the dead and must now do the will of the living. There are at
least three usages of the term related to computers and the Internet.
1) In one form of
denial of service attack, a zombie is an insecure Web server on which malicious
people have placed code that, when triggered at the same time as other zombie
servers, will launch an overwhelming number of requests toward an attacked Web
site, which will soon be unable to service legitimate requests from its users.
A pulsing zombie is one that launches requests intermittently rather than all
at once.
A more recent use
of zombies is to use them as an army of unwitting spam purveyors.
2) On the World
Wide Web, a zombie is an abandoned and sadly out-of-date Web site that for some
reason has been moved to another Web address. It's a ghost site that appears to
have moved. Zombies contribute to linkrot.
3) In the Unix
operating system world, developers sometimes use the term to refer to a program
process that has died but hasn't yet given its process table entry back to the
system.
