Hello Bluesky! I did a thing and now I am the proud owner of the greatest hat in the world! 🎓
Coming back from south east Asia, there are so many small things I immediately notice about my home, the Ruhr area. There is too little workers helping people behave better, like keeping a bit of distance away from the baggage belt (there were no markings either).

This is a friendly reminder that the call for contributed talks to Real World Crypto in Taipei 2026 is open until October 10. We are looking for interesting talks bridging cryptography and its real-world use! Also it’s a great way to meet new people! rwc.iacr.org/2026/contrib...

We found a new vulnerability in TLS. It's a variant of the ALPACA attack that bypasses current countermeasures. Relativly low impact - but great insight! Check it out: opossum-attack.com

Als Mitglied des Exzellenzclusters CASA erforscht @veelasha.bsky.social die Systeme unseres alltäglichen Gebrauchs, wie etwa unsere Smartphones. Am 22. Mai entscheidet sich, ob CASA und damit die Forschung von Moonsamy und ihren Kolleg*innen weiter gefördert wird. Daumen drücken! 🤞
