'Hackers have found a new way to amplify the crippling effects of
denial-of-service techniques by abusing an improperly implemented tool
found in almost 1 million network-connected cameras, DVRs, and other
Internet-of-things devices.

The technique abuses WS-Discovery, a protocol that a wide array of
network devices use to automatically connect to one another. Often
abbreviated as WSD, the protocol lets devices send user datagram
protocol packets that describe the device capabilities and
requirements over port 3702. Devices that receive the probes can
respond with replies that can be tens to hundreds of times bigger. WSD
has shipped with Windows since Vista and is one of the ways the
operating system automatically finds network-based printers.'
