Note: The Guest Talk will be given over Zoom due to the COVID-19 pandemic.

Abstract:

We will start with a short introduction of Internet Exchange Points (IXPs) and their operations. With this background, we will discuss the topic of Distributed-Denial-of-Service (DDoS) attacks at IXPs. We present results of a recent measurement study of DDoS-for-hire Websites (Booters) and the traffic effects of a seizure operation of 15 Booter websites by the FBI in late 2018. Subsequently, we introduce the concept of Advanced Blackholing, a published and operational mechanism designed by the DE-CIX research team to defend IXP links against DDoS attacks. Due to the current COVID-19 situation, we will close the presentation by showing some preliminary results on the traffic shifts caused by nation-wide lockdowns in several countries.
