 Phishing is a type of social engineering attack that uses fraudulent emails or other forms of communication to trick users into revealing sensitive information, such as passwords, credit card numbers, or personal details.

Phishing emails usually target a large number of users indiscriminately, hoping that some of them will fall for the scam.
