Keystroke logging (often called keylogging) is the action of tracking (or logging) the keys struck on a keyboard, typically in a covert manner so that the person using the keyboard is unaware that their actions are being monitored. There are numerous keylogging methods, ranging from hardware and software-based approaches to electromagnetic and acoustic analysis. Remote keyloggers enable locally recorded data from a remote location. 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 unwittingly as spyware and executed as part of a rootkit or remote administration (RAT) Trojan horse. A keylogger program typically consists of two files that get installed in the same directory: a dynamic link library (DLL) file (which does all the recording) and an executable 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 periodically to whoever installed the program.Remote communication may be achieved using one of these methods:

• Data is uploaded to a website, database or an FTP server.
• Data is periodically emailed to a pre-defined email address.
• Data is wirelessly transmitted by means of an attached hardware system.
• The software enables a remote login to the local machine from the Internet or the local network, for data logs stored on the target machine to be accessed.

Detecting the presence of a keylogger on a computer can be difficult. So-called anti-keylogging programs have been developed to thwart keylogging systems, and these are often effective when used properly.
