Hardware Keyloggers can be used for Keystroke logging. They plug inbetween a computer keyboard and a computer and log all keyboard activity on an internal memory.

They are designed to work with PS/2 keyboards, and more recently with USB keyboards.

How do they work?

All hardware keyloggers have to have the following:

  • A microcontroller - this interprets the datastream between they keyboard and computer, processes it, and passes it to the non-volatile memory
  • A non-volatile memory - this stores the recorded data, even when power is lost
