Over the past few months, I have left my comfort zone and begun working on Agentic AI systems. For that, I am now trying to fill several roles, so if that sounds like something you'd like to work on with me, please get in touch.

Submissions are now open for the SPIQE Workshop! Submit your work until 12th of March AoE! ⚛️ spiqe.cool

At the gpg.fail talk and omg #39c3 You can just put a \0 in the Hash: header and then newlines and inject text in a cleartext message. Won’t even blame PGP here. C is unsafe at any speed. gpg has not fixed it yet.

I strongly believe that AI will have a lasting impression on human to human communication. Expectations will be presented as prompts rather than as opportunities. The response to non-compliance will be reinforcement rather than reflection. And success will be judged by how well the recipient obeyed.

Announcing SPIQE 2026: 2nd Workshop on Secure Protocol Implementations in the Quantum Era, bringing together researchers and implementers to securely deploy PQC! 📍 Co-located with Euro S&P in Lisbon, Portugal, July 6-10, 2026 spiqe.cool #SPIQE2026 #EuroSP #PostQuantumCrypto

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

Man lese und lösche umgehend seinen Twitter-Account, falls immer noch nicht geschehen. Unfaßbar, was @arminwolf.at versucht hat und wie er an X, den Iren, der EU und (natürlich) an den USA scheitert.

Eamonn and I received a Zama Cryptanalysis Grant to help with the lattice estimator github.com/malb/lattice.... We hope to hire interns to work on the estimator over two periods over the next 18 months. Zama are still taking applications for this grant, see here: www.zama.ai/post/announc...

Kinderschutz im Netz bleibt oft Theorie: Informatikerin Veelasha Moonsamy untersuchte mit Kolleg*innen aus Belgien und den Niederlanden rund 70.000 Werbeanzeigen auf Webseiten für Kinder – mit alarmierenden Ergebnissen. 👉 news.rub.de/wissenschaft... (Foto: Roberto Schirdewahn)

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! 🤞

Goodbye @ruhr-uni-bochum.de Hello @uni-wuppertal.bsky.social Today is my first day at BUW. Super excited to join this awesome place. Looking forward to many interesting projects and collaborations. If you would like to join or collaborate with our brand new IT security group get in touch with me.

We (@lambdafu.bsky.social & me) found a critical security vulnerability in the #Erlang/OTP SSH daemon that allow attackers to execute arbitrary code via network access on devices running Erlang/OTP SSH servers. This vulnerability is #CVE-2025-32433, patches out now. Estimated CVSSv3 10.

Update on crypto.iacr.org/2025/

Come join us at the SPIQE workshop in Munich in June! spiqe-workshop.github.io - we are now open for paper submissions and talk proposals on all aspects of secure protocol implementation for the post-quantum era.

Die nächsten vier Jahre werden die entscheidenden sein. Wir können nicht stehen bleiben, wo wir sind. Deshalb sage ich es mit aller Dringlichkeit: Veränderung braucht den Willen zur Verantwortung. Und genau dafür bitte ich am Sonntag um Eure und Ihre Stimme. youtu.be/UE0_-84oqwo
