During a security audit, a penetration tester observes abnormal redirection of all traffic for a...

CEH v13 states that DNS server hijacking occurs when attackers compromise the authoritative DNS infrastructure and alter DNS zone records to redirect all legitimate queries to malicious destinations. Unlike DNS cache poisoning, which affects specific resolvers temporarily, server hijacking manipulates the core DNS authority controlling the domain. This results in a complete redirect for all users, regardless of geographic location or device configuration. CEH emphasizes that such attacks can lead to large-scale credential theft, phishing, financial fraud, and session compromise because the attacker presents an identical clone site while retaining full control of DNS routing. DNS tunneling is used for covert data exfiltration and does not redirect traffic. DNS rebinding targets browser policies, not global DNS redirection. DNS amplification is a volumetric DDoS technique unrelated to zone manipulation. The scenario matches DNS server hijacking exactly.
