That's a wrap!
The 16th AISec workshop went great!
Three outstanding keynote speakers and two insightful poster sessions. I'm proud of this community. Thanks to all contributors!

Get rid of bad reviewers? 🤔
Today, @_thrsten presents our work @USENIXSecurity on misleading the automatic assignment of reviewers at large conferences (e.g. #CVPR or #NeurIPS). Our attack generates adversarial papers that select their own reviewers. @bifoldberlin @CASA_EXC 1/5

Congratulations Dr. @_thrsten

[Thorsten Holz @thorstenholz]

Systems for automatic paper-reviewer assignments (e.g., TPMS - https://t.co/qml0ucsNPp) are used during the reviewing process of conferences such as @icmlconf. In https://t.co/EJYgs0m7zZ, we explore how authors might try to game these systems. We propose an attack that adapts...

Congratulations Dr. @doreenriepel!

Hackers are revealing that quadcopter operators aren’t nearly as hidden as they might think, but researchers have released a tool that can intercept and decode that signal. https://t.co/N6vLJOIbKb

Nico Schiller from Ruhr-Universität Bochum is presenting his work on Drone Security and the Mysterious Case of DJI's DroneID at #NDSS23, talking about how attackers could eavesdrop on the drone's over-the-air data traffic!

I am happy to announce that our paper "Password-Authenticated Key Exchange from Group Actions" has been accepted to CRYPTO 2022
- joint work with Michel Abdalla, Thorsten Eisenhofer @_thrsten, Eike Kiltz @crypto_theory and Sabrina Kunzweiler

[Nico Schiller @74ck_0]

This is what DJI’s Drone-ID packets look like. every drone broadcasts this data all the time.
we managed to receive + decode the packets over the air. no encryption. (we saw some confusion around that before)

Ein ganz praktisches Beispiel ist der "Alexa-Hacking-Demonstrator" – PhD-Student @_thrsten vom @CASA_EXC zeigt, wie #Sprachassistenten so manipuliert werden können, dass sie versteckte Botschaften wahrnehmen. @ruhrunibochum

#ACSAC2020 Voice Security pt 2 -- Pivoting from defense to attack, @leaschnherr presents a robust approach for over-the-air adversarial examples to attack automatic speech recognition. Fittingly, the system is dubbed "Imperio," an unforgiveable curse! ; )

Achievement unlocked: @zdf_logo, a news program for kids, featured our work on smart speakers and my daughters watched it 😍

We performed a study of accidental triggers, i.e., sounds that should not have triggered a voice assistant. You can find some results at https://t.co/gNlMyg4atY. Joint work with @m33x, @leaschnherr, @_thrsten, @DorotheaKolossa and Jan Wiele

very happy to announce our #ICML2020 paper on better detecting #fakeimages with the help of frequency transforms :) thx to all for the great collaboration 😃 @joool_f @leaschnherr @thorstenholz @_thrsten @asjafischer @CASA_EXC @casafant
