Guest Talk by Matthias Wichtlhuber from DE-CIX

We are delighted to annouce a Guest Talk by Matthias Wichtlhuber (DE-CIX), who will be talking about countermeasures against Distributed-Denial-of-Service (DDoS) attacks at DE-CIX and also about internet traffic changes due to the COVID-19 lockdown observed at DE-CIX.

When: Tuesday, 2020-04-21, 11:00
Where: Zoom Meeting ID: 916 2538 0906, Password: 091338

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


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.


Matthias Wichtlhuber holds a Diploma in Information Systems from Universit├Ąt Mannheim and a Ph. D. from Technische Universit├Ąt Darmstadt. His Ph. D. thesis focused on optimizing content delivery on the Internet. During his Ph. D. he worked on numerous EU and nationally funded research projects as well as industrial projects. After his studies, he joined DE-CIX, the operator of the largest Internet Exchange Point (IXP) in the world in Frankfurt. He is a member of the DE-CIX research team and works on product development, system security, future network architectures for Internet exchange points, and large-scale network data analysis.
