Open SSDP Report

LAST UPDATED: 2022-08-29

This report identifies hosts that have the Simple Service Discovery Protocol (SSDP) running and accessible on the Internet.

These services have the potential to be used in amplification attacks by criminals that wish to perform denial of service attacks.

For more details behind the scan methodology and a daily update of global SSDP scan statistics please visit our dedicated SSDP scan page.

You can learn more on the report in our Open SSDP Report tutorial.

You can learn more on our reports in general in our Overview of Free Public Benefit Shadowserver Reports presentation, which also explains example Use Cases.

For more information on our scanning efforts, check out our Internet scanning summary page.
