ITPEC FE Morning October 2020 Question 35
ITPEC FE Morning October 2020 — Question 35 of 80
DNS Cache Poisoning — identify the attack where false records are injected into a DNS cache.
DNS cache poisoning injects fraudulent domain-to-IP mappings into a DNS server's cache, redirecting users to a malicious server without their knowledge.
Why not others:
- (b) Obtaining DNS software version info is reconnaissance/footprinting, not cache poisoning
- (c) Using a DNS server to flood a target with recursive queries is a DNS amplification attack (DDoS)
- (d) Extracting zone information (full domain list) from a DNS server is a DNS zone transfer attack
Key rule: Cache poisoning = fake DNS records in cache → users redirected to attacker's server.
