Which term describes a DNS-based attack intended to mislead users by altering DNS data?

• A. DNS Poisoning
• B. DNS
• C. Dig
• D. Direct

Answer: (A)

DNS poisoning describes an attack that corrupts DNS data so that domain lookups resolve to attacker-controlled IP addresses. By tampering with the mapping in a resolver’s cache or at an authoritative DNS server, a user who types a legitimate domain could be redirected to a fraudulent site without realizing it. This enables phishing, malware distribution, or other harm because the user thinks they’re visiting a trusted site, but the IP address returned by DNS points somewhere else. The other options aren’t attacks: DNS is the system that translates names to addresses, not an attack itself. Dig is a tool used to query DNS information, not a method of manipulation. Direct isn’t a recognized term for a DNS-based attack.
