What is DNS Poisoning?#
Attackers spoof forged responses to DNS recursive revolvers. The resolver caches the fraudulent IP, misdirecting unsuspecting users to credential-harvesting phishing replicas.
Everyday Analogy#
Altering street signs overnight so travelers driving toward the official bank branch are deceived into arriving at a replica setup by thieves.
Practical Applications#
- Implementing DNSSEC cryptographic validation to protect domain reputation
- Hardening enterprise recursive DNS infrastructure
