Keylogger

What Is a Keylogger?

There are three major types of hardware keyloggers:

1. Hidden camera loggers used to visually monitor keystrokes. 
2. USB-loaded keyloggers that deliver a keystroke logger malware to a computer
3. Keyboard hardware keyloggers that are either built-in or connected to a device via a cable.

Keyloggers also have legitimate use cases. For instance, system administrators may use keylogging software to track employees’ activities. Keyloggers are also useful for law enforcement as they can be used to monitor criminals and send all recorded information to all offices efficiently.

In the current ecosystem, keyloggers have grown from spying tools often used by criminals or governmental organizations to a commercial market of their own, allowing the average individual to purchase their own copy of keylogging software. A common, more benign use case of keyloggers is parental control, where parents can monitor their children’s online activities.
