Es un tipo de
troyano que se caracteriza por capturar y almacenar las pulsaciones efectuadas
sobre el teclado. Posteriormente esta información (que puede contener
información sensible) se envía a un atacante, que las puede utilizar en su
propio provecho.
Las ultimas
versiones de este tipo de programas maliciosos también hacen capturas de
pantalla del equipo atacado. De esta forma, se hace ineficaz e inseguro el uso
del teclado virtual.

Programa que
intercepta todas las pulsaciones realizadas en el teclado (e incluso a veces
también el ratón), y las guarda en un archivo para obtener datos sensibles como
contraseñas, etc. Posteriormente puede ser enviado a un tercero sin
conocimiento ni consentimiento del usuario.

Key loggers are used to
monitor keyboard activity on a PC. These can be software-based (bundled with
Trojan horses, adware, and spyware) or hardware-based (between the keyboard
cable and the PC, acoustic etc.) Usually this information is retrieved across a
local network, the internet, or from the physical device connected to the
keyboard.
PC Security Handbook, Rich Robinson
A virus that logs a user's
keystrokes as they type in order to capture private information, passwords or
credit card information. Occasionally,
key loggers can be physical devices attached to a PC.

A device that monitors and
records keyboard usage. [NIST-SP800-83:2005]
is a diagnostic used in
software development that captures the user's keystrokes. It can be useful to
determine sources of error in computer systems and is sometimes used to measure
employee productivity on certain clerical tasks. Such systems are also highly
useful for law enforcement and espionagefor instance, providing a means to
obtain passwords or encryption keys and thus bypassing other security measures.
However, keyloggers are widely available on the Internet and can be used by
anyone for the same purposes.

Keyloggers are programs that
can monitor and record your every keystroke, exposing you to the risk of
identity theft by revealing user names, passwords and other confidential
information.

A keylogger, sometimes
called a keystroke logger, key logger, or system monitor, is a hardware device
or small program that monitors each keystroke a user types on a specific
computer's keyboard. As a hardware device, a keylogger is a small battery-sized
plug that serves as a connector between the user's keyboard and computer.
Because the device resembles an ordinary keyboard plug, it is relatively easy
for someone who wants to monitor a user's behavior to physically hide such a
device "in plain sight." (It also helps that most workstation
keyboards plug into the back of the computer.) As the user types, the device
collects each keystroke and saves it as text in its own miniature hard drive.
At a later point in time, the person who installed the keylogger must return
and physically remove the device in order to access the information the device
has gathered.

Les keyloggers (de
l'anglais Keystroke Logger, enregistreur de frappes de touches) sont des petits
programmes espions qui enregistrent toutes les frappes sur les touches d'un
clavier. Régulièrement, le keylogger envoie les informations ainsi collectées
au pirate. Les keyloggers les plus sophistiqués ne se contentent pas
d'enregistrer les frappes sur le clavier mais effectuent également des captures
d'écran. Les keyloggers constituent une atteinte à la confidentialité des
ressources.
