A recently discovered distributed denial of service technique that abuses the Web Services Dynamic Discovery specification is being executed in the wild by multiple threat actors to amplify the effects of their attacks, researchers have warned.

A spoofing attack leveraging this protocol causes a targeted internet-based server to send an overwhelming number of responses, using up its bandwidth, explains researchers at Akamai Technologies in a blog post yesterday. Akamai recently detected such an attack against one of its own clients in the gaming industry, states blog author Jonathan Respeto, security intelligence response team engineer at Akamai.
