Keylogging is a method used to record the keystrokes made on a computer or mobile device. This technique can be employed for various purposes, including monitoring user activity, gathering information, or even malicious intent. Keyloggers can be software-based, installed on a device without the user's knowledge, or hardware-based, involving physical devices connected to the keyboard. The data collected by keyloggers can reveal sensitive information, such as passwords, credit card numbers, and personal messages. While some organizations use keylogging for legitimate reasons, such as employee monitoring, it is often associated with cybercrime and privacy violations, making it a significant concern in the realm of cybersecurity.
