Amplification Attack

Definition: An amplification attack is a DDoS technique that exploits vulnerabilities in network protocols to generate a large volume of traffic from a small number of requests, amplifying the attack’s impact.

Example: In a DNS amplification attack, an attacker sends a small DNS query (e.g., 64 bytes) to a DNS server, spoofing the victim’s IP address. The server responds with a much larger packet (e.g., 3000 bytes) to the victim, amplifying the traffic by nearly 47 times.
