What is keylogger ?

A keylogger is a type of supervision software (considered to be either  or spyware) that has the potential to record every keystroke you make to a , usually . A keylogger recorder can record , , and any information you type at any time using your . The log file created by the keylogger can then be sent to a specified receiver. Some keylogger  will also record any e-mail addresses you use and  you visit.

Keyloggers, as  a surveillance tool, are often used by employers to ensure employees use work computers for business purposes only. Unfortunately, keyloggers can also be embedded in allowing your information to be transmitted to an unknown third party.

 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 collect each keystroke and save it as text in its own miniature . 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

A keylogger program does not require physical access to the user's computer. It can be downloaded on purpose by someone who wants to monitor activity on a particular computer or it can be downloaded without knowing as  and executed as part of a  or remote administration (RAT) . A keylogger program typically consists of two files that get installed in the same directory: a dynamic link library () file (which does all the recording) and an  file (.EXE) that installs the DLL file and triggers it to work. The keylogger program records each keystroke the user types and uploads the information over the Internet occasionally to whoever installed the program.

Although keylogger programs are promoted for gentle purposes like allowing parents to monitor their children's whereabouts on the Internet, most privacy advocates agree that the potential for misuse is so great that legislation should be enacted to clearly make the unauthorized use of keyloggers a criminal offense.
