What Is a Keylogger? How it works

You may be wondering, What Is a Keylogger? Simply put, a keylogger is a monitoring tool that secretly records every keystroke on a device. It can exist as software or hardware, often running unnoticed in the background. While some organizations use them for legitimate purposes like employee monitoring or parental control, most are linked to cybercrime. Hackers often deploy keylogger malware to capture sensitive data such as login details, banking information, and private conversations.
There are two main types: software keyloggers and hardware devices. Both pose major security risks, leading to identity theft, fraud, and account breaches. Protecting yourself involves using updated antivirus tools, enabling two-factor authentication, and practicing safe browsing habits.
