Dear colleagues, today (14 August) between 16:00 and 22:00 (Germany timezone) takes place the first workshop on Traffic Manipulation Attacks and Defences, ManTra 2020. The workshop takes place digitally through Zoom. The goal of the workshop is to foster research on traffic manipulation attacks and defences and to bridge the gap between academia, industry and standardisation organs. The scope of the workshop includes understanding the landscape of traffic manipulation attacks, learning about the attackers (cyber criminals, security agencies, govts...), inferring vulnerabilities, ... and devising countermeasures, including challenges towards their deployment on real Internet networks. Full details are available on the workshop web site. The workshop is open to all SIGCOMM participants; so far SIGCOMM has way over 1000 registered participants. The registration is still open and highly affordable. The first ManTra workshop features talks from top researchers and expert practitioners in the area and is chaired by Haya Shulman and Radia Perlman. The program of the workshop is here: https://conferences.sigcomm.org/sigcomm/2020/workshop-mantra.html Click on the talks' titles to read the abstracts. I encourage all who are interested in the topic to join us today and interact with our renowned speakers and program committee. The recordings of the ManTra workshop will be available through ACM SIGCOMM after the event. The ManTra workshop is sponsored by the ATHENE National Research Center for Applied Cybersecurity in Darmstadt.
