We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

Also this project started out as a Master's thesis @kit.edu @kitinformatik.bsky.social @kastel-labs.bsky.social
Karl did an amazing job 💪 He pushed super-hard for the best possible result, which eventually was accepted at AsiaCCS 2025. Congratz again 🥳🎉

LLM-powered code assistants might suggest vulnerable code to specific user groups. Old news? Well, in contrast to prior attacks of this kind, our "Generalized Adversarial Code Suggestions" (AsiaCCS 2025) impose no restrictions on the vulnerabilities.

Yikes. Turns out you can send a plaintext radio signal to cause any train in the USA to do an emergency break. The original 'security' was just a checksum, no encryption or authentication. Reporting this took them 12 years (!) because the vendor dismissed it initially www.cisa.gov/news-events/...

LLMs hallucinating nonexistent software packages with plausible names leads to a new malware vulnerability: "slopsquatting."

LLMs can't stop making up software dependencies and sabotaging everything

I will be giving a talk at the MPI-IS @maxplanckcampus.bsky.social in Tübingen next week (March 12 @ 11am). The talk will cover my group's overall approach to trust in ML, with a focus on our work on unlearning and how to obtain verifiable guarantees of trust.

In doing so, we not only excel in backdoor removal with a *worst case* remaining ASR of 0.48% (on Tiny-ImageNet with a ResNet34) but also in maintaining accuracy on the primary task of 56.65% (no defense) and 56.31% (HARVEY) *in the worst case* across different backdooring attacks. (4/5)

Our method refines this reference model thru a combination of splitting poisonous and benign samples, learning on poisonous and unlearning benign samples, and splitting the dataset again over multiple rounds. Eventually, we use the samples from the final split to train a perfectly benign model (3/5)

Christian Wressnegger @chwress.bsky.social · Feb 21

The idea is to remove poisonous samples that might introduce a backdoor during training. While learning a benign model is difficult in this setting, it is rather easy to learn a strongly backdoored model. This strongly backdoored model can serve as an oracle to find poisonous samples (2/5)

I'm happy to share that our paper "Learning the Backdoor to Remove the Backdoor" got accepted at #AAAI2025 as oral presentation (top 5%). Great job @qzhao903.bsky.social 💪 @kastel-labs.bsky.social @kit.edu (1/5)

I got Linux running in a PDF file using a RISC-V emulator.

PDFs support Javascript, so Emscripten is used to compile the TinyEMU emulator to asm.js, which runs in the PDF. It boots in about 30 seconds and emulates a riscv32 buildroot system.

The additional "ess" is a typo, though, and the bsky account unrelated 🫠 However, fun fact: ESS is the acronym of the underlying Helmholtz topic of our beloved KASTEL Security Research Labs -> @kastel-labs.bsky.social 😎
