• How Do LLM Agents Actually Get the Flag? Trace-Level Provenance for Agentic Offensive Security Evaluation

Source: arXiv cs.CR — Aug 28 arXiv:2608.26237v1 Announce Type: new Abstract: Capture-the-Flag (CTF) benchmarks are widely used to assess the offensive security capabilities of autonomous language-model agents. Evaluations rely on shallow binary judgments or aggregate scores, overlooking the agent's trajector

• Unsaid, Unsafe? Implicit Security Obligations in LLM-Based RTL Code Generation

Source: arXiv cs.CR — Aug 28 arXiv:2608.26588v1 Announce Type: new Abstract: Large Language Models (LLMs) generate register-transfer-level (RTL) code with rapidly improving functional correctness. Security of LLM-generated code, however, has been studied mainly for software, where flaws can still be patched

• KubeCap: A Framework for Capability Minimization in Kubernetes via Static Analysis and LLM-Assisted Rule Inference

Source: arXiv cs.CR — Aug 28 arXiv:2608.26699v1 Announce Type: new Abstract: As the most widely used container orchestration platform, Kubernetes provides flexible privilege configuration by allowing developers to manage Linux capabilities via manifest files. However, developers rely on default settings or c

• Daydreaming: Stealing Hidden Agent Skills through Black-Box Task Interaction

Source: arXiv cs.CR — Aug 28 arXiv:2608.26733v1 Announce Type: new Abstract: Agent skills bundle instructions, reference data, and executable helpers that let a general agent perform specialized tasks. Hosted providers can keep these files secret while selling access to task results, making the skill itself

• Are We Shooting Flies with Cannons? Trade-off Analysis for AI-based 5G Intrusion Detection

Source: arXiv cs.CR — Aug 28 arXiv:2608.26844v1 Announce Type: new Abstract: The increasing adoption of Artificial Intelligence (AI) in network intrusion detection raises the question of whether complex and computationally expensive models are justified for this task. In this work, we investigate the trade-o

• PLCBench: Can Autonomous LLM Agents Turn PLC Access into Sustained Physical Impact?

Source: arXiv cs.CR — Aug 28 arXiv:2608.26882v1 Announce Type: new Abstract: Industrial control systems (ICSs) rely on programmable logic controllers (PLCs) to connect networked computation with physical control. Tool-using large language model (LLM) agents represent an emerging attack threat: can an autonom

• The Guard That Cried Wolf: How Scary Words Make Agent Guardrails Refuse Legitimate Actions

Source: arXiv cs.CR — Aug 28 arXiv:2608.27009v1 Announce Type: new Abstract: Agent guardrails are checks that approve or refuse each action before an LLM executes it. Sometimes they refuse requests that are genuinely safe. This over-safety blocks deployment when a guardrail refuses an authorized task. Evalua

• The Framing Gap: Indirect Prompt-Injection Exfiltration Defeats Surface-Level Defenses in Tool-Using Agents

Source: arXiv cs.CR — Aug 28 arXiv:2608.27092v1 Announce Type: new Abstract: A tool-using LLM agent that reads attacker-controlled web content while holding a secret faces indirect prompt injection: the content may make it exfiltrate the secret. In a safe synthetic lab (canary secret, mock tools, matched cle

• Just a rumour of a bug is enough to find a security exploit these days

Source: Simon Willison — Aug 28 Just a rumour of a bug is enough to find a security exploit these days Anil Madhavapeddy is a professor of computer science at Cambridge and a core maintainer of the OCaml compiler. In this somewhat alarming post he reports that security issues in OCaml projects are seeing eviden

• Breaking Claude Code Opus 5 Auto Mode

Source: Simon Willison — Aug 27 Breaking Claude Code Opus 5 Auto Mode Anthropic are putting a great deal of faith in Claude Code's auto mode for protecting their coding agent users against prompt injection attacks. They recently made that the default and have made bold claims about its effectiveness. Johann Reh

• Qwen3.8-Flash-Next

Source: Simon Willison — Aug 26 Qwen3.8-Flash-Next Another open weights model from Qwen. This one is "a multimodal MoE model that also serves as an early preview of the architecture used in Qwen4". It's pretty big: 125B tokens, but only 6B active which means it gets a significant performance boost. I've been tr

• Quoting Paul Dix

Source: Simon Willison — Aug 26 The fact that AI wrote 1M LOC and then refined it over the course of the next couple of months to produce a reliable piece of software that is currently running on millions of developer machines is absolutely mind blowing. And you can say, “well it’s not that impressive because t

• EVE Online: The Move to Python 3 Begins!

Source: Simon Willison — Aug 25 EVE Online: The Move to Python 3 Begins! EVE Online has been one of the most interesting case studies in Python at scale for over twenty years now. They've been running on Stackless Python since their launch in 2003, and their last major upgrade was 16 years ago, to Stackless Pyt

• llm-anthropic 0.27

Source: Simon Willison — Aug 24 Release: llm-anthropic 0.27 This release of the Anthropic plugin for LLM mainly provides compatibility with the recently released anthropic v1.0.0 Python library, which switches from httpx to httpx2. OpenAI made the same change in their v3.0.0 release two weeks ago. Anthropic pro

• Your executable is a SQLite database

Source: Simon Willison — Aug 24 Your executable is a SQLite database Farid Zakaria describes a neat Linux pattern for creating a SQLite database file that can be directly used as an executable binary. The trick sets the SQLite file format's 4-byte application ID (68 bytes into the file) to SELF, standing for St

• Anthropic’s best AI model struggles to attract users as cheaper tools thrive

Source: Simon Willison — Aug 23 Anthropic’s best AI model struggles to attract users as cheaper tools thrive A few interesting numbers in this FT story gathered from "people with knowledge of the matter": Anthropic's "annualized revenue" for July is up to $65bn - it was $47bn in May, and I collected more histor

• Quoting Drew Breunig

Source: Simon Willison — Aug 23 Prior to Fable, it felt silly to waste too much time improving your coding harness or context strategies. A new model would arrive at the same price (or cheaper!) and paper over most of your problems. But then Fable landed. It was (and still is!) incredible. But the cost was so h

• Quoting Linus Torvalds

Source: Simon Willison — Aug 22 And this was a debug session from hell, enormously helped by an AI doing much of the grunt-work. I'd like to call it my tireless helper, but the AI several times stated flat out that this was impossible and unsolvable and that we should just write a report about it. I suspect tho

• llm 0.33

Source: Simon Willison — Aug 22 Release: llm 0.33 My highlights from this release: Upgraded to the OpenAI Python library 3.x and switched the HTTP client dependency from httpx to httpx2. #1608, #1631 I shipped a quick 0.32.1 fix for this yesterday, but this is the more comprehensive fix. llm embed and llm embed

• More than just code review

Source: Simon Willison — Aug 22 The key skill required to make productive use of coding agents is being able to confidently instruct them on how to make changes and then confidently verify that those changes have been applied in the correct way. Sometimes this involves reviewing every line of code they have wri
