What term describes the technique of altering DNS mappings to redirect requests to a rogue server?

• A. DNS Multiplexing
• B. DNS Amplification Attack
• C. DNS Server Hijacking
• D. DNS Spoofing Attack

Answer: (C)

This is about DNS server hijacking. It describes gaining control of a DNS server (or its zone data) and changing its mappings so that domain names resolve to an attacker-controlled, rogue server. By editing A records (and possibly NS records) for a domain, the server returns the rogue IP, redirecting traffic transparently and enabling phishing, malware, or data theft. This differs from DNS spoofing, which involves forging responses to a resolver (often via cache poisoning) rather than changing the server’s stored data. The key idea is that the attacker has compromised the DNS server itself and modifies its mappings to misdirect users.
