wow — the preprint host, arxiv, is banning authors for a year if they submit papers with hallucinated citations 🤖

If generative AI tools generate inappropriate language, plagiarized content, biased content, errors, mistakes, incorrect references, or misleading content, and that output is included in scientific works, it is the responsibility of the author(s). 2/

We have recently clarified our penalties for this. If a submission contains incontrovertible evidence that the authors did not check the results of LLM generation, this means we can't trust anything in the paper. 3/

The penalty is a 1-year ban from arXiv followed by the requirement that subsequent arXiv submissions must first be accepted at a reputable peer-reviewed venue. 4/

Examples of incontrovertible evidence: hallucinated references, meta-comments from the LLM ("here is a 200 word summary; would you like me to make any changes?"; "the data in this table is illustrative, fill it in with the real numbers from your experiments") end/"

I find this unsettling: A new study in #Lancet shows that the number of faux citations in scientific articles is on the rise, and #AI is likely to blame. @aniloza.bsky.social reports. www.statnews.com/2026/05/07/l...

Yesterday, Lukas presented at #ICSE2026 results I didn't believe when he first showed them to me. A classifier based on simple code metrics matches frontier LLMs for vulnerability discovery in performance, as long as they are not agentic. 🧵 (1/4)

Paper: LLM-based Vulnerability Discovery through the Lens of Code Metrics

Code Metrics perform as well as LLM-based classifiers for source code vulnerabilities! I'm glad the community didn't shoot the messenger when I presented our recent work at ICSE'26. preprint: mlsec.org/docs/2026-ic... Shout out to Felix, Erik, Jonas, @eisenhofer.bsky.social and @rieck.mlsec.org

AI predicts rain. We predict trouble! Today, Erik presents a novel attack on Google's latest AI weather model at #CCS2025. By changing only 0.1% of the observations, the attack can fabricate or suppress the prediction of extreme events, from hurricanes 🌀 to heat waves 🔥 1/4 @bifold.berlin

Thank you to Stefan Halfpap, Haralampos Gavriilidis, Lukas Pirch, and Stephanie Brandl for their excellent tutorials this afternoon at #BIFOLDDay2025. We look forward to the Spring Reception starting at 4 PM! @lpirch.bsky.social @stephaniebrandl.bsky.social @harrygav.bsky.social

Konrad Rieck 🌈@rieck.mlsec.org · last yr.

Great to be at @satml.org with several members of my team from @bifold.berlin and @tuberlin.bsky.social. We are having a blast with exciting discussions and talks on trustworthy AI! #SaTML25

initial commit. add README and a pic of us driving to #SaTML25 this morning 🚲☀️
