We’re excited to announce this year’s competitions for @satml.org 🎉 Get ready for four challenges tackling AI in space, backdoors in LLMs, CTF agents, and privacy-preserving databases. satml.org/competitions/ Let’s dive in! 🧵1/5

Did AI folks not value your security insights or vice versa? Maybe you’re submitting your papers to the wrong conference. @satml.org has you covered! We are eager to read your work on the security, privacy, and fairness of AI. 👉 satml.org/call-for-pap... ⏰ Deadline: Sep 24

Many of us assume that clicking “blur” or activating a virtual background protects our privacy. This research shows: that belief is misleading. The safest option is still the simplest one: prepare your real environment for calls instead of relying solely on digital masking.

Study: Seeing through: Analyzing and Attacking Virtual Backgrounds in Video Calls Felix Weißberg, Jan-Malte Hilgefort, Steve Grogorick, Daniel Arp, Thorsten Eisenhofer, Martin Eisemann, Konrad Rieck. Proceedings of the 34th USENIX Security Symposium, 2025. @tuberlin.bsky.social @tuwien.at

The team developed an attack that exposed 53% more background pixels than previous methods, showing just how much information can unintentionally slip through.

These fragments are often invisible to the human eye, but when collected over time, they can be used to reconstruct rooms and even identify personal objects.

Virtual backgrounds leak tiny image fragments of the real environment – so-called pixel leaks. These fragments are often invisible to the human eye, but when collected over time, they can be used to reconstruct rooms and even identify personal objects.

The “digital curtain” in video calls has holes – with the right techniques, people can see through. New MLSec study (BIFOLD) reveals that virtual backgrounds in video conferencing tools are not a reliable privacy shield. t1p.de/ndqxt #ML #Security #Cybersecurity #IT #Study @rieck.mlsec.org

Got some hot research cooking? 🔥 The @satml.org paper deadline is just 9 days away. We are looking forward to your work on security, privacy, and fairness in machine learning. 👉 satml.org/call-for-pap... ⏰ Sep 24

Whoa. 100 responses from speakers at CHES, and only one is presenting by video. Maybe their conference is actually worth going to?

Three weeks to go until the SaTML 2026 deadline! ⏰ We look forward to your work on security, privacy, and fairness in AI. 🗓️ Deadline: Sept 24, 2025 We have also updated our Call for Papers with a statement on LLM usage, check it out: 👉 satml.org/call-for-pap... @satml.org

Trump admin planning to change student visas from lasting for duration of academic program to fixed 4-yr term, and then much harder to renew Could destroy US ability to attract global talent, particularly those seeking advanced degrees in STEM. The median time to complete a PhD is 5.7 yrs per NSF.

📣 Researchers in AI security, privacy & fairness: It's time to share your latest work! The SaTML 2026 submission site is live 👉 hotcrp.satml.org 🗓️ Deadline: Sept 24, 2025 @satml.org

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. 🌐 https://intellisec.de/research/adv-code (1/3)

Just noticed my "Julia for Machine Learning" course got 2^8 stars on GitHub, yay! 🎉 github.com/adrhill/juli...

Today I have a more serious topic than usual, please consider reposting for reach: My wife and I are urgently looking for a specialist in neuropediatrics or a similar field for our autistic child with a diagnosed, but not further specified, movement disorder [1/4]

Thank you senator Katharina Günther-Wünsch, Senatsverwaltung für Bildung, Jugend und Familie, for taking the time to visit the BIFOLD booth at LNdW 2025. We believe that AI education belongs in schools and we try to get the next generation of scientists interested in AI research at an early stage.

Thrilled to share a recent opinion piece at the IEEE Security and Privacy (Vol. 23, Issue 3). Basically a long-term perspective on the field meant for both researchers and practitioners. 📝 ieeexplore.ieee.org/stamp/stamp....

Our demo "mlidea: Interactively Improving ML Data Preparation Code via 'Shadow Pipelines'" was accepted at VLDB! 🥳 We demo suggestions for ML pipelines, similar to IntelliJ code inspections or Grammarly suggestions youtu.be/ePGm1J6S2qk Joint work w/ @mersault.bsky.social @p-groth.bsky.social

All @acm.org publications will be 100% Open Access as of January 2026. When we announced this at POPL and CHI this year, conference participants spontaneously erupted in applause. The CS community is excited about ACM's move to OA!

Occasionally, I get a reviewer complaining, “You don’t compare against any other approach. So how can we know you’re better?” So I found a simple way to still add the "bold number column" that apparently everybody wants these days.

Huge congrats to @spalab.cs.ucr.edu's Georgi Ganev for receiving the Distinguished Paper Award at IEEE S&P for his work "The Inadequacy of Similarity-based Privacy Metrics: Privacy Attacks against “Truly Anonymous” Synthetic Datasets." Paper: arxiv.org/pdf/2312.051...

Haven't seen this on Bluesky yet: S&P 2027 will take place in Montreal, Canada!

🎉Hats off to Dr. Stefan Blücher! He defended his PhD yesterday🎓 Thesis: "Towards Scalable and Transparent ML Algorithms with Applications in Explainable AI and Quantum Chemistry" Thanks to all supporters! #XAI #QuantumML #MLResearch #PhDCompleted @tuberlin.bsky.social @fraunhoferhhi.bsky.social

Our paper "Top Score on the Wrong Exam" paper will be presented at #ISSTA25 🐣 in Trondheim! 📝https://mpi-softsec.github.io/papers/ISSTA25-topscore.pdf 🧑‍💻https://github.com/niklasrisse/TopScoreWrongExam // @nrisse.bsky.social @fuzzing.bsky.social

I had two NSF grants terminated last week, for a total of just under $1M. The largest one had just started and its goal was to provide users with more context and information on the content that they see on social media.

I was invited to review for the "Journal of Pipeline Systems Engineering and Practice", seems our work on ML pipelines is finally recognised by other communities as well ;D

🚨 SaTML is searching for its 2026 home! Interested in becoming General Chair and hosting the conference in your city or institution? We’d love to hear from you. Place a bid here: 👉 forms.gle/kbxtwZddpcLD...

Uncle Sam abruptly turns off funding for CVE program. Yes, that CVE program

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

This is something conference organizers are (or should be) acutely aware of... www.science.org/content/arti...

Here’s an extended version of my PhD defense talk about our work on *representational alignment between humans 🧠 and machines 🤖 for computer vision* that I gave two weeks ago at the Max Planck Institute for Human Cognitive and Brain Sciences www.cbs.mpg.de/cbs-coconut/...

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.
