What term describes altering or adding forged DNS records into the DNS resolver cache to redirect DNS queries?

• A. DNS spoofing
• B. Intranet DNS spoofing
• C. DNS cache poisoning
• D. Internet DNS poisoning

Answer: (C)

DNS cache poisoning is the technique of injecting forged DNS records into a recursive resolver’s cache so that future queries for a domain are answered with an attacker-controlled IP address. This exploits the resolver’s caching behavior, causing users to be directed to a malicious site or service instead of the legitimate one. While DNS spoofing is a related idea of forging responses, the precise term for putting false entries into a resolver’s cache is DNS cache poisoning. The other phrases aren’t standard labels for this specific cache-targeted attack.
