2. DNS Cache Poisoning
Attackers inject false DNS responses into resolver caches, causing users to be directed to malicious IPs even with correct DNS records.

Using open DNS resolvers, attackers send small queries that generate massive responses โ amplifying their attack bandwidth 70ร.
4. DNS Tunneling
Attackers exfiltrate data by encoding it in DNS queries, bypassing firewalls that don't inspect DNS traffic.
