Stupidly Simple DDoS Protocol (SSDP) generates 100 Gbps DDoS

This post details a significant 100 Gbps+ Distributed Denial of Service (DDoS) attack leveraging the Simple Service Discovery Protocol (SSDP), commonly used by UPnP. It explains how misconfigured firewalls can expose UPnP-enabled devices to the internet, allowing attackers to spoof source IPs and trigger large amplification responses from these devices. The post provides technical details on the attack, including packet analysis, reflector IP distribution, and the amplification factors achieved by SSDP, highlighting the ongoing challenge of mitigating novel DDoS vectors.
