We already did a very similar thing with popular messenger apps earlier (https://t.co/LJAMOQio4H #NDSS23) but now, when using Silent SMS, probing users and fingerprinting their whereabouts remains entirely unnoticed on their device.

Excited to share that our research "Freaky Leaky SMS: Extracting User Locations by Analyzing SMS Timings" has been accepted to @USENIXSecurity '23.

Was a lot of fun with the team: Evangelos Bitsikas (too cool to be on twitter), @the0retisch, @XtinaPoepper

I'm on the job market! I address online abuse as the next frontier of security & privacy, so all people using tech feel safe. Open to TT faculty/industry research roles in the US/abroad -- lmk if you know of a good home for my work!

Die Vonovia nötigt ihren Mieter:innen smarte Rauchmelder auf. Das Gerät einer in China ansässigen Firma sammelt völlig unnötige Daten. Und wer seine eigenen Daten nutzen will, muss zustimmen, sie mit der Vonovia zu teilen. Über eine US-Cloud. Klingt absurd? Fand ich auch.

@WikiRogi Mieten in NL ist eher ungewöhnlich, vor allem langfristig, deshalb gibt's dafür kaum Markt. Wenn dann übergangsweise, befristet auf 6 oder 12 Monate, und dann zu Mondpreisen.

Hier wird gekauft und hinterher wieder verkauft. Man hängt nicht dran. Anderes Land, andere Mentalität.

Got military-grade security? Sure. But is it Victor Goeman-proof? Your home security cameras might not be, as shown in the paper “Reverse Engineering the Eufy Ecosystem: A Deep Dive into Security Vulnerabilities and Proprietary Protocols”

This paper provides a more systematic and more detailed analysis of the work presented at last year's @USENIXSecurity.

Oder mit #Freiheit bei der Wahl der Fortbewegungsart 🚄🚲🚗.
Oder mit Minimierung von Bürokratie.
Oder mit Förderung von selbstgenutztem Wohneigentum ohne Fantasieabgaben.

Aber nicht wegen 30% steuerfreiem Einkommen über 5 Jahre 🫣

Biometric #authentication is insecure. That's why you need to remember and enter a six-digit PIN every few months to continue using biometry for login. The PIN is only used for this single purpose, for nothing else. 😵‍💫
