Phishing Domains: Identifying and Blocking Malicious Web Threats

Phishing domains are deceptive websites designed to mimic legitimate brands and steal sensitive user information such as login credentials, credit card details, or personal data. Cybercriminals register lookalike domains with slight variations—such as misspelled URLs or added characters—to trick users into clicking malicious links. These domains are often distributed through email, SMS, or ads and can be difficult to detect without advanced threat intelligence. Organizations must employ domain monitoring tools, real-time URL filtering, and DNS security measures to identify and block phishing domains proactively. Educating users and implementing browser security policies are key to defending against these increasingly sophisticated attacks.
