SSDP amplified reflective DDoS attacks: The Internet Storm Center (ISC) InfoSec Handlers Diary Blog writes about a recent -significant- increase in both scanning for 1900/UDP and a huge increase of 1900/UDP being used for amplified reflective DDOS attacks: 1900/UDP (SSDP) Scanning and DDOS
1900/UDP is the Simple Service Discovery Protocol (SSDP) which is a part of Universal Plug and Play (UPnP). The limited information available to me indicates that the majority of the devices that are being used in these DDOS attacks are DLink routers, and some other devices, most likely unpatched or unpatchable and vulnerable to the UPnP flaws announced by HD Moore in January of 2013.
