Source: arXiv cs.CR — Jul 24 arXiv:2607.20730v1 Announce Type: new Abstract: Large language models increasingly use search tools to retrieve up-to-date information, introducing a new attack surface in which retrieved documents can be manipulated. This risk is amplified by the development of generative engine

• Which Model Is Actually Serving You? IRIS: Budgeted Black-Box Auditing of Model Substitution and Routing Dilution in LLM Gateways

Source: arXiv cs.CR — Jul 24 arXiv:2607.20860v1 Announce Type: new Abstract: Commercial LLM gateways mediate access to hosted models, but the served backend may not match the advertised one: it may substitute a cheaper model on every request or route only a fraction $\epsilon$ of requests to it. Prior black-

• Toward cryptographically verifiable authorization for autonomous AI agents: A security hypothesis, preliminary formal model, and proof-of-concept implementation

Source: arXiv cs.CR — Jul 24 arXiv:2607.21325v1 Announce Type: new Abstract: Autonomous AI agents increasingly execute actions, invoke tools, and operate on protected resources with limited human oversight. Existing authentication and authorization mechanisms establish identity and delegate authority, but do

• TopoGuard: Graph Theory Based Defenses Against Split-Knowledge Attacks on RAG

Source: arXiv cs.CR — Jul 24 arXiv:2607.20437v1 Announce Type: cross Abstract: Production Retrieval Augmented Generation (RAG) systems rely on aggregating multiple external documents to answer complex queries. However, the retrieved documents introduce a new threat surface that can be exploited to launch spl

• Isolating LLM Alignment from Regex: Zero Coverage and Metric-Dependent Divergence Under Adversarial Mutation

Source: arXiv cs.CR — Jul 24 arXiv:2607.20494v1 Announce Type: cross Abstract: Production LLM applications commonly stack a regex filter in front of model-side alignment; prior work found no measurable coverage gain from adding a live Gemini backend behind an active regex filter. We ask whether that ceiling

• The first known runaway AI agent - or a very bad marketing stunt?

Source: Simon Willison — Jul 23 The first known runaway AI agent - or a very bad marketing stunt? Martin Alderson's commentary on the OpenAI accidental cyberattack against Hugging Face includes a couple of details I hadn't considered. First, Hugging Face offers a truly rich target if you're trying to find poten

• Quoting Seth Larson

Source: Simon Willison — Jul 23 The Python Package Index (PyPI) now rejects new files being uploaded to releases that are older than 14 days. This restriction was put in place to prevent old and long-stable releases from being poisoned in case publishing tokens or workflows of PyPI projects were compromised. As

• Quoting Thomas Ptacek

Source: Simon Willison — Jul 22 I genuinely believe that if you took an open weights model from 2025 and built a pentest harness for it, it could do this kind of sandbox escape and scan/hack in most networks. This is only surprising because you assume OpenAI has sounder sandboxes. — Thomas Ptacek, doesn't

• OpenAI’s accidental cyberattack against Hugging Face is science fiction that happened

Source: Simon Willison — Jul 22 This story is wild. The short version: OpenAI were running a cybersecurity test against an unreleased model, with the model's guardrail features turned off. Rather than solve the test, the model broke its way out of OpenAI's sandbox, then found exploits to break in to Hugging Fac

• Are AI labs pelicanmaxxing?

Source: Simon Willison — Jul 22 Are AI labs pelicanmaxxing? Excellent piece of work by Dylan Castillo, who took a deep-dive into the frequently pondered question of whether the AI labs have been deliberately training models to draw pelicans riding bicycles in response to my deeply unscientific benchmark. I've b

• Orchestrions

Source: Simon Willison — Jul 22 San Francisco tip: it only costs around $15 ($10 in quarters plus a $5 bill for the self-playing violin) to activate every single Orchestrion in Musée Mécanique. And because most people are bad at allocating their funds you may well be the ONLY person activating the Orchestrions,

• Who’s Afraid of Chinese Models?
