A keylogger, short for “keystroke logger,” is a type of spyware that records and steals consecutive keystrokes inputted by a user on a device. When unsuspecting individuals type on their keyboards, they often input confidential information like online banking credentials, social security numbers, and personal messages. Hackers can leverage keylogging to capture these sensitive details and obtain information about a users’ social media activity, email responses, visited websites, and even sent text messages. They may also use this data to potentially gain unauthorized access to a user’s accounts, servers, or databases.
