DNS Hijacking — the unauthorized alteration or redirection of DNS resolution so users are sent to attacker-chosen destinations.

Use input validation and contextual output encoding, parameterized queries, session protection, least privilege, updates, rate controls, a WAF, and monitoring. No single filter replaces secure development.
