What is keylogger
A Keylogger is malicious software that hides itself inside your computer. The keylogger records keystrokes (i.e. each time you type something on the keyboard) and then sends this information to the attacker. By grabbing your sign-in credentials and other sensitive information and sending them to an attacker, keyloggers enable an attacker to login to your accounts, impersonate you and initiate fraudulent transactions.
