Announcing my latest first-author paper, accepted to #DIMVA2026: ❄️ FROST: Fingerprinting Remotely using OPFS-based SSD Timing.

Our PhD students, Carina Fiedler, @snee.la and @hannesweissteiner.com attended the NDSS Symposium 2026 in San Diego, California, this week to present their papers! Check them out in the thread 👇

I'm looking forward to presenting my paper, "Continuous User Behavior Monitoring using DNS Cache Timing Attacks" at NDSS next week! We mount an Evict+Reload-style attack on the local DNS cache, detecting recently accessed domains and evicting to continuously monitor new accesses.

I'm excited to announce that my first first-author paper is accepted at NDSS 2026 🥳. Eviction Notice: Reviving and Advancing Page Cache Attacks Check it out at: snee.la/posts/evicti... @snee.la, @notimaginary.bsky.social, Lukas Maar, @gruss.cc from @isec-tugraz.bsky.social, @tugraz.bsky.social

Join us tomorrow for the InfoSec + SSD Christmas special, featuring real-world exploits, live hacking of various targets, information leaks, file formats, and a review of the year in security. 📅 December 17th, 2025 | 17:30 📍 Lecture Hall HS i13, Inffeldgasse 16b

We got 9th place at @defcon.bsky.social #CTF! Props to all finalists for an intense fight over the past three days and congrats to MMM for taking the win. Thanks to Nautilus Institute for the neat setup this year, we had a blast. Until next time, Vegas! #DEFCON #DEFCON33

I am happy to announce that my first paper has been accepted at USENIX Security! We propose TEEcorrelate, a mitigation that statistically decorrelates reported performance counters from real ones during TEE execution.

I'm very happy to announce our new Cohere+Reload: Re-enabling High-Resolution Cache Attacks on AMD SEV-SNP was accepted at DIMVA 2025! In it @snee.la, @gruss.cc and I investigate AMD's ciphertext coherence mechanism and show even low resolution leakage can go a long way. Paper preview: cr.giner.cc
