Open SSDP Report

LAST UPDATED: 2023-02-21

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.

Local Manual Testing

If you would like to test your own device to see if it has SSDP (UPnP) enabled, you can do the following. In one window, start tcpdump with the command:

tcpdump -n host [IP]

and then in a second window, enter:

perl -e ‘print “M-SEARCH * HTTP/1.1\r\nHost:239.255.255.250:1900\r\nST:upnp:rootdevice\r\nMan:\”ssdp:discover\”\r\nMX:3\r\n\r\n”‘ > /dev/udp/[IP]/1900

If your device has SSDP enabled, you should see a fair amount of traffic on the tcpdump window.

    Time that the IP was probed in UTC+0
  • ip
    The IP address of the device in question
  • protocol
    Protocol that the DNS response came on (usually UDP)
  • port
    Port that the SSDP response came from
  • hostname
    Reverse DNS name of the device in question
  • tag
    Will always be SSDP
  • header
    The initial HTTPU (HTTP over UDP) header that was received
  • asn
    ASN of where the device in question resides
  • geo
    Country where the device in question resides
  • region
    State / Province / Administrative region where the device in question resides
  • city
    City in which the device in question resides
  • systime
    GMT timestamp when the response was created
  • cache_control
    Cache-control — how long to wait for more communication
  • location
    URL of where the XML service description is located
  • server
    Server information of a Host that supports UDAP
  • search_target
    Search Target (ST) value
  • unique_service_name
    USN field contains compilation of uuid:uuid_of_Host_device::ST_of_response
  • amplification
    Amplification factor (This amplification is is based solely on the payload size sent and payload size received)
  • response_size
    Response size in bytes
