End of an era! A quick update to let everyone know that our i386 kernel and images will no longer be released. A process that started in 2003 is now complete for us. The last i386 CPUs appear to have been made in 2007. Full details on the blog: kali.org/blog/end-of-i3…

Cock.li has issued a "RED ALERT" as it faces a major threat, requiring the team to work full-time to keep the service online. Without user support—through donations and spreading awareness—the service might shut down. The account registration and password change

!Buenas tardes! El próximo 12 de diciembre estaremos realizando la conferencia gratuita OWASP Rio de la Plata en la Torre de las Comunicaciones de Antel. Toda la información y el registro gratuito de inscripción en: appsecriodelaplata.org

Pleased to announce PQConnect: pqconnect.net Easy-to-install software for your Linux box (more OSes coming later) to protect network applications against future quantum computers. Paper will appear at NDSS 2025. Joint work with Tanja Lange, Jonathan Levin, Bo-Yin Yang.

Palisade Research just caught OpenAI's O1 model doing something wild. While testing it at chess, it hacked the entire system instead of playing. The most fascinating part? No one told it to. No one suggested it. Let me explain 🧵

There are many papers with attack analyses: sometimes analyses of specific algorithms, sometimes "security proofs" covering many algorithms. What fraction of these papers are wrong? <1%? >50%? I have a new plan to convincingly settle the debate: cr.yp.to/papers.html#er…

Great job by the OCCULT team @MITRE for sharing their methodology for evaluating LLMs in offensive cyber operations (OCO)! 🔥 ✅ Paper: arxiv.org/abs/2502.15797 Their framework moves beyond simple pass/fail assessments by introducing structured, repeatable benchmarks that

You should use Signal. Seriously. There are other encrypted messaging apps out there, but I don’t have as much faith in their longevity. In particular I have major concerns about the sustainability of for-profit apps in our new “AI” world.

At RWPQC today, ANSSI drops Classic McEliece from its list of recommended PQC KEMs — a notable change from earlier guidance. One to watch for anyone following PQC deployment.

Happy to announce the newest crypto microlibrary: lib1305 (lib1305.cr.yp.to) has fast code from Kaushik Nath for Poly1305 on Intel/AMD CPUs; e.g. 0.8 cycles/byte on Skylake and Zen 2, twice as fast as the S&P 2024 paper. Also includes automatic fallback to portable code.

I'll be at the Open Source Summit with the netlabs team! Stop by at the booth to talk about cybersecurity or reach out to me.

Today I'm at Open Source Summit in Denver. If you're around let me know!

Quantum computers haven't factored anything interesting yet. Peter Gutmann concludes that quantum computing is "not getting anywhere" (theregister.com/2025/07/17/qua…). The same logic 70 years ago would have said we'll never land on the Moon. More on this analogy: blog.cr.yp.to/20250118-fligh…
