What is a keylogger and how can it be used as a form of malware?
A keylogger is a type of software or hardware device that records every keystroke made on a computer or mobile device. It can be used for legitimate purposes like monitoring employee activity or parental control. However, when used as malware, a keylogger can secretly capture sensitive information such as passwords, credit card numbers, and personal messages without the user's knowledge or consent. This information can then be used for malicious activities like identity theft or financial fraud.
