Hardware keylogger

A hardware keylogger is like a secret spy that sits in between your keyboard and your computer. It's a small device that looks like a USB stick or a circuit board.

When you type anything on your keyboard, the hardware keylogger records every single keystroke and stores it inside its memory. This means that everything you type, like letters, numbers, and even passwords, can be seen by the person who planted the hardware keylogger.

It can be difficult to detect a hardware keylogger because it doesn't show up on your computer like a virus or malware. The best way to prevent someone from using a hardware keylogger on your computer is to make sure that you don't leave your computer unattended or connect any suspicious devices to it.

So remember: a hardware keylogger is like a sneaky spy that records what you type, so always keep an eye on your computer and be careful about what you connect to it.
