Keystroke logging, keystroke hardware and software information

A Keylogger (KeyLogger, Key Logger, or Keystroke Logger) is a process/program that usually runs in the background, recording keystrokes.

I mean, how many of you check your office machines for keystroke loggers (hardware) on the back of your stationary PC? Or list running process with your taskmanager for suspicious processes or activity?

I do, but consider me an extremely paraonid freak! As this is in the field of my work, I am excused.

Anyway a quick exmaple from the real world. I have come across several keyloggers while visting some countries public internet cafe's. So avoid doing bank transactions or credit card buys on a non trusted public computer! Non trusted computer is = every public computer.

It's very easy to use a keylogger. Either as hardware device, which you pluging on a PS/2 or USB port on the computer, between the keyboard and the port the keyboard uses to connect to the computer, or as software running in hidden mode, collecting every keystroke.
