Phishing is a type of scam designed to steal personal information like usernames, passwords, and credit card details. Scammers do this by sending fraudulent emails or messages that appear to come from legitimate sources and direct users to enter details on fake websites that look like the real ones. They use technical tricks to make the links and websites look authentic. Some ways to avoid phishing include being wary of unsolicited requests for information, checking for security indicators on websites, and using anti-phishing software and spam filters.
