Source: arXiv cs.CR — Apr 17 arXiv:2604.14444v1 Announce Type: new Abstract: Ensuring the reliability of machine learning-based intrusion detection systems remains a critical challenge in Internet of Things (IoT) environments, particularly as data poisoning attacks increasingly threaten the integrity of mode

• NeuroTrace: Inference Provenance-Based Detection of Adversarial Examples

Source: arXiv cs.CR — Apr 17 arXiv:2604.14457v1 Announce Type: new Abstract: Deep neural networks (DNNs) remain largely opaque at inference time, limiting our ability to detect and diagnose malicious input manipulations such as adversarial examples. Existing detection methods predominantly rely on layer-loca

• CBCL: Safe Self-Extending Agent Communication

Source: arXiv cs.CR — Apr 17 arXiv:2604.14512v1 Announce Type: new Abstract: Agent communication languages (ACLs) enable heterogeneous agents to share knowledge and coordinate across diverse domains. This diversity demands extensibility, but expressive extension mechanisms can push the input language beyond

• Hijacking Large Audio-Language Models via Context-Agnostic and Imperceptible Auditory Prompt Injection

Source: arXiv cs.CR — Apr 17 arXiv:2604.14604v1 Announce Type: new Abstract: Modern Large audio-language models (LALMs) power intelligent voice interactions by tightly integrating audio and text. This integration, however, expands the attack surface beyond text and introduces vulnerabilities in the continuou

• Route to Rome Attack: Directing LLM Routers to Expensive Models via Adversarial Suffix Optimization

Source: arXiv cs.CR — Apr 17 arXiv:2604.15022v1 Announce Type: new Abstract: Cost-aware routing dynamically dispatches user queries to models of varying capability to balance performance and inference cost. However, the routing strategy introduces a new security concern that adversaries may manipulate the ro

• Emulation-based System-on-Chip Security Verification: Challenges and Opportunities

Source: arXiv cs.CR — Apr 17 arXiv:2604.15073v1 Announce Type: new Abstract: Increasing system-on-chip (SoC) heterogeneity, deep hardware/software integration, and the proliferation of third-party intellectual property (IP) have brought security validation to the forefront of semiconductor design. While simu

• Feedback-Driven Execution for LLM-Based Binary Analysis

Source: arXiv cs.CR — Apr 17 arXiv:2604.15136v1 Announce Type: new Abstract: Binary analysis increasingly relies on large language models (LLMs) to perform semantic reasoning over complex program behaviors. However, existing approaches largely adopt a one-pass execution paradigm, where reasoning operates ove

• Layered Mutability: Continuity and Governance in Persistent Self-Modifying Agents

Source: arXiv cs.CR — Apr 17 arXiv:2604.14717v1 Announce Type: cross Abstract: Persistent language-model agents increasingly combine tool use, tiered memory, reflective prompting, and runtime adaptation. In such systems, behavior is shaped not only by current prompts but by mutable internal conditions that i

• datasette 1.0a28

Source: Simon Willison — Apr 17 Release: datasette 1.0a28 I was upgrading Datasette Cloud to 1.0a27 and discovered a nasty collection of accidental breakages caused by changes in that alpha. This new alpha addresses those directly: Fixed a compatibility bug introduced in 1.0a27 where execute_write_fn() callback

• datasette 1.0a27

Source: Simon Willison — Apr 15 Release: datasette 1.0a27 Two major changes in this new Datasette alpha. I covered the first of those in detail yesterday - Datasette no longer uses Django-style CSRF form tokens, instead using modern browser headers as described by Filippo Valsorda. The second big change is that

• Quoting John Gruber

Source: Simon Willison — Apr 15 The real goldmine isn’t that Apple gets a cut of every App Store transaction. It’s that Apple’s platforms have the best apps, and users who are drawn to the best apps are thus drawn to the iPhone, Mac, and iPad. That edge is waning. Not because software on other platforms is gett

• Gemini 3.1 Flash TTS

• Quoting Kyle Kingsbury

I set Claude Code for web the task of figuring out what it can do, build

• Quoting Bryan Cantrill

Source: Simon Willison — Apr 13 The problem is that LLMs inherently lack the virtue of laziness. Work costs nothing to an LLM. LLMs do not feel a need to optimize for their own (or anyone's) future time, and will happily dump more and more onto a layercake of garbage. Left unchecked, LLMs will make systems larg

• Gemma 4 audio with MLX

• SQLite 3.53.0

Source: Simon Willison — Apr 11 SQLite 3.53.0 SQLite 3.52.0 was withdrawn so this is a pretty big release with a whole lot of accumulated user-facing and internal improvements.
