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

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. wired.trib.al/CIKDIDe

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!

For the 9th role model in our #WomenInITS series, everything circles around #cryptographic keys and mathematical puzzles: @doreenriepel is PhD student @BochumCrypto since 2019. There is also a puzzle hidden on her poster. Who can solve it? 😉More info 👉bit.ly/3ecNVHs

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) @merlinchlosta 1/n

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

Watch me at #rc3 in Chaos West Stream, 18:00 Berlin time. I am sharing insights from a research I did for @STRG_F. I collected my Alexa data and met the people behind the speakers. Faboulus scientists @m33x and @leaschnherr will join for Q&A later. Hope to see/hear you there 🚀

#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! ; )

We performed a study of accidental triggers, i.e., sounds that should not have triggered a voice assistant. You can find some results at unacceptable-privacy.github.io. Joint work with @m33x, @leaschnherr, @_thrsten, @DorotheaKolossa and Jan Wiele
