Emails and phishing links scam people by impersonating trustworthy sources. They often contain urgent or enticing messages, prompting recipients to click on links or download attachments. These links lead to fake websites designed to steal personal information like login credentials or credit card details. Phishing links can also install malware on devices, compromising security. It's crucial to verify email sources, avoid clicking on suspicious links, and never share sensitive information unless certain of the sender's legitimacy.
