You can track latest WS-Discovery scan results on the Shadowserver Dashboard. We do not perform any intrusive checks on a discovered service. We scan by sending 5 byte malformed WS-Discovery packet containing a payload, as used in the Phenomite research WS-Discovery DDoS amplification. The WS-Discovery service is known to be a potential UDP message amplifier that has been abused for reflected DDoS attacks since 2019 (see observations from Akamai and Trend Micro).Īs of we find 17621 servers on IPv4, with an average amplification factor of 293 and median amplification factor of 305. As described on Wikipedia, Web Services Dynamic Discovery ( WS-Discovery) is a technical specification that defines a multicast discovery protocol to locate services on a local network. This report identifies accessible WS-Discovery services on port 3702/udp.
