Yesterday, we celebrated the official opening of the new Cybersecurity Campus Graz building! 🔑✨

After the celebratory speeches, Verena Schröppel, Edona Fasllija, and Lukas Maar, three of our researchers, shared their academic journeys and research topics.

🎉 Congratulations, Martin! 🎉

Martin Heckel (@lunkw1ll) successfully defended his #PhD thesis “Real-World Rowhammer: Understanding and Addressing the Challenges to Rowhammer Attacks” yesterday. 🥳
We wish him the best in his future endeavors!

🎉 Congratulations, Aikata! 🎉

She successfully defended her #PhD thesis “Secure and Efficient Implementations of Post-Quantum Cryptographic Algorithms” today. 🥳
We wish her the best in her future endeavors!

The discovery of the longest pattern ever for DDR5 Rowhammer flips! 😱

Join us for Kaveh Razavi’s talk “Rowhammer bit flips a decade later”:

📅 April 1st, 2026 | 11:00
📍 CCG Seminar room, CCGEG002

Abstract:
The first Rowhammer exploit was published a little more than a decade ago on a DDR3-based system. Since then, we have had two generations of DRAM technology with proprietary mitigations. In this talk, I present our journey in understanding the security guarantees of these mitigations in DDR4 and DDR5 devices through significant platform building efforts, painstaking reverse engineering, and creative system-level techniques. The results are not encouraging; DRAM is as insecure as a decade ago while the cost of independent security analysis is growing beyond what academia can do. I finish with a brief discussion of possible paths forward.

What a week!
Our move is completed and from now on, you can find us at Sandgasse 38a. 🎉

A big thank you to everyone who made this quick transition possible. 🫶

Our PhD students, Carina Fiedler, Sudheendra Neela (@vmcall) and Hannes Weissteiner (@hweissi) attended the NDSS Symposium 2026 in San Diego, California, this week to present their papers!
