Phishing compromises online security by tricking users into revealing sensitive information, such as passwords or credit card details. Attackers typically use deceptive emails, websites, or messages impersonating legitimate organizations. When users interact with these fraudulent communications, they unwittingly provide personal data or download malicious software. As a result, phishing attacks can lead to identity theft, financial loss, and unauthorized access to accounts. Awareness and training about phishing are vital for individuals and organizations to mitigate these risks effectively.
