How Attackers Turn 1 Gbps Into 100 Gbps: DDoS Amplification

How does an attacker with a modest internet connection take down a target on a much bigger pipe? They borrow bandwidth from servers all over the internet through two techniques: reflection and amplification. This video walks through both techniques end to end. You will learn what reflection is and why it requires UDP, what amplification is and how the amplification factor works, the classic protocols that get abused (DNS, NTP, SSDP, CharGen, memcached), the full packet flow from spoofed query to victim flood, and the layered defenses that work at the internet level and at the victim's edge.
