Phishing compromises online security by tricking individuals into revealing sensitive information, such as passwords and financial data. Attackers often use deceptive emails, messages, or websites that mimic legitimate organizations to gain victims' trust. By clicking on these fraudulent links, users may unknowingly download malware or be directed to fake websites designed for data theft. Phishing attacks exploit human psychology, creating a sense of urgency or fear to encourage hasty decisions. As these tactics become more sophisticated, they pose significant risks to personal and organizational security, necessitating rigorous user education and improved security protocols.
