Which of the following is used by attackers to record everything a person types, including usernames, passwords, and account information?

Packet sniffing involves intercepting and analyzing network traffic but does not directly record keystrokes made on a local machine unless the keystrokes are transmitted unencrypted over the network.

Keystroke logging, also known as keylogging, is specifically designed to record every keystroke a user makes, which directly captures usernames, passwords, and other sensitive information typed into a system.

Spoofing involves masquerading as another entity to gain unauthorized access or mislead systems, but it is not a method for recording user keystrokes.

Wiretapping involves monitoring telephone or internet communications, which is different from recording inputs made directly on a computer via the keyboard.
