• Context Contamination in LLM Analysis of Network Security Logs: Poison with Passive Prompt Injection and Mitigation Evaluation

Source: arXiv cs.CR — Jul 17 arXiv:2607.14493v1 Announce Type: new Abstract: Large Language Models are increasingly deployed in Security Operations Centers for log analysis tasks including summarization, alert triage, and threat investigation. These systems ingest logs from external-facing services and proce

• Bad Memory: Evaluating Prompt Injection Risks from Memory in Agentic Systems

Source: arXiv cs.CR — Jul 17 arXiv:2607.14611v1 Announce Type: new Abstract: A growing class of agentic systems maintain persistent state across sessions through memory files, behavioral preferences, and knowledge bases. While this makes agents more useful and self-improving, it also creates a new attack sur

• MemPoison: Uncovering Persistent Memory Threats and Structural Blind Spots in LLM Agents

Source: arXiv cs.CR — Jul 17 arXiv:2607.14651v1 Announce Type: new Abstract: Persistent external memory enhances agent continuity but introduces persistent security vulnerabilities: adversarial content can be injected via standard interaction channels, retained across turns, and later distort downstream beha

• FlowGuard: From Signals to Evidence for MCP Security Detection

Source: arXiv cs.CR — Jul 17 arXiv:2607.14754v1 Announce Type: new Abstract: The Model Context Protocol (MCP) enables LLM agents to interact with external tools through metadata exchange, tool invocation, and response consumption. Existing MCP security scanners primarily reason about suspicious semantic sign

• Is External Database Protection Static in Retrieval-Augmented Generation? Rethinking Privacy Preservation under Dynamic Queries

Source: arXiv cs.CR — Jul 17 arXiv:2607.14811v1 Announce Type: new Abstract: Retrieval-augmented generation (RAG) enhances large language models via external document retrieval, but retrieved contexts may leak sensitive information. Current privacy protection methods typically rely on a document-level static

• A Queueing-Stability Criterion for Causal IPD-QIM Network Flow Watermarking

Source: arXiv cs.CR — Jul 17 arXiv:2607.14954v1 Announce Type: new Abstract: On multi-hop encrypted links such as Tor and cascaded VPNs, tunneling flattens packet lengths and protocol fields, leaving inter-packet delay (IPD) as the main carrier for active flow attribution. Causality lets the embedder delay p

• DataShield: Uncovering Risky Fine-Tuning Data Across LLMs Through Consensus Subspace Alignment

Source: arXiv cs.CR — Jul 17 arXiv:2607.15081v1 Announce Type: new Abstract: Fine-tuning large language models (LLMs) on domain-specific datasets has become a standard paradigm for adapting LLMs to specialized applications. However, recent work has shown that even fine-tuning on benign task-specific data can

• Setup Complete, Now You Are Compromised: Weaponizing Setup Instructions Against AI Coding Agents

Source: arXiv cs.CR — Jul 17 arXiv:2607.15143v1 Announce Type: new Abstract: AI coding agents set up projects by reading documentation and installing the dependencies it lists, without verifying their names, sources, or known vulnerabilities. By editing only a README, requirements file, or Makefile, an attac

• Beyond Success Rate: Cost-Aware Evaluation of Offensive and Defensive Security Agents

Source: arXiv cs.CR — Jul 17 arXiv:2607.15263v1 Announce Type: new Abstract: Security-agent evaluations commonly measure peak offensive capability under generous inference budgets, emphasizing vulnerability discovery, exploit development, penetration testing, and CTF completion. Such measurements are useful

• Traceback Translators Against Forgetting in Continual Fake Speech Detection

Source: arXiv cs.CR — Jul 17 arXiv:2607.12569v1 Announce Type: cross Abstract: Fake speech detectors are increasingly challenged by the development of new and more accurate generative models. To cope with this problem, continual learning techniques are nowadays widely considered feasible strategies for updat

• Breaking Refusal in the First Half: A Mechanistic Study of the Prefill Jailbreak

Source: arXiv cs.CR — Jul 17 arXiv:2607.14147v1 Announce Type: cross Abstract: Aligned language models refuse harmful requests, but a one-line prefill ("Sure, here is") strips the refusal. We ask where and how it fails. The harm representation stays intact: on the prompts the attack flips to compliance, a li

• Stop Means Stop: Measuring and Repairing the Enforcement Gap in Agent-Framework Control Primitives

Source: arXiv cs.CR — Jul 17 arXiv:2607.14166v1 Announce Type: cross Abstract: Production LLM-agent frameworks expose control primitives -- human-in-the-loop approval gates, run cancellation, and execution timeouts -- whose names and documentation imply barrier semantics: while a run is paused, cancelled, or

• Value Leakage: An LLM's Answers Are Silently Shaped by Its Own Values

Source: arXiv cs.CR — Jul 17 arXiv:2607.14345v1 Announce Type: cross Abstract: People use language models for practical questions whose answers are difficult to verify. We show that models exhibit covert value leakage: the information they provide is influenced by their own values, without this influence bei

Here's my blog, running in Firefox, running in WebAssembly, running in Chrome: They chose Firefox/Gecko because it has strong single-process su

• Kimi K3, and what we can still learn from the pelican benchmark

• Quoting Linus Torvalds

Source: Simon Willison — Jul 16 I realize that some people really dislike AI, but this is an area where I'm willing to absolutely put my foot down as the top-level maintainer. Linux is not one of those anti-AI projects, and if somebody has issues with that, they can do the open-source thing and fork it. Or just

• Quoting Armin Ronacher

Source: Simon Willison — Jul 14 The shared language of a software project is not English or Python but it is the common understanding of what its concepts mean, where the boundaries are, which invariants matter, who owns what, and why the system has the shape it does. This language is rarely written down in one

• datasette 1.0a37

• DOOMQL

Source: Simon Willison — Jul 13 DOOMQL Peter Gostev built this using GPT-5.6 Sol. This is a lot of fun: DOOMQL started with a deliberately unreasonable question: what if SQLite were the game engine, not merely the place where a game stores data? The result is a small, original Doom-like game in which SQL owns m

• datasette code-frequency chart on GitHub

Source: Simon Willison — Jul 13 datasette code-frequency chart on GitHub Out of curiosity I decided to see if I could find a useful illustration of the impact of coding agents and Opus 4.5 class models on my own output.

• Directly Responsible Individuals (DRI)

Source: Simon Willison — Jul 12 Directly Responsible Individuals (DRI) I went looking for a definition of "Directly Responsible Individuals" and the best I found was in the GitLab handbook.

• Fable gets another bump

Source: Simon Willison — Jul 12 One of the consequences of GPT-5.6 Sol being clearly a Fable/Mythos class model is that Anthropic have, once again, bumped the date that Fable stops being available in their Claude Max plans: We're extending Claude Fable 5 access on all paid plans, as well as keeping Claude Code’

• sqlite-utils 4.1.1

• Quoting Nilay Patel

Source: Simon Willison — Jul 10 The reality is to make augmented reality glasses, you need to put a camera next to your eyes that is continuously recording everything you see and processing that to put information over it.
