What is a Memcached DDoS Attack and How Can You Stop It?

NETSCOUT Arbor can confirm a 1.7Tbps reflection/amplification attack targeted at a customer of a U.S. based Service Provider has been recorded by our ATLAS global traffic and DDoS threat data system. The attack was based on the same memcached reflection/amplification attack vector that made up the Github attack. It’s a testament to the defense capabilities that this Service Provider had in place to defend against an attack of this nature that no outages were reported because of this.

The previous record recorded by ATLAS was 650Gbps towards a target in Brazil during the summer of 2016.
