The Rust version of sudo (sudo-rs) used in Ubuntu 25.10 has two moderate security vulnerabilities. Updates are being released to address these issues, including preventing password leaks and improving feedback handling.
This page details how to control shopping cart wheels using audio signals from a phone, exploiting the 7.8 kHz signal used for locking/unlocking. It provides audio files to lock, unlock, arm, and perform purchase checks on Gatekeeper Systems and Rocateq wheels.
Details the restrictions when using a public MQTT broker with Meshtastic, focusing on TLS/SSL requirements, authentication, and potential issues with server reliability and rates.
Answering end user security questions is challenging. While large language models (LLMs) like GPT, LLAMA, and Gemini are far from error-free, they have shown promise in answering a variety of questions outside of security. We studied LLM performance in the area of end user security by qualitatively evaluating 3 popular LLMs on 900 systematically collected end user security questions. While LLMs demonstrate broad generalist ``knowledge'' of end user security information, there are patterns of errors and limitations across LLMs consisting of stale and inaccurate answers, and indirect or unresponsive communication styles, all of which impacts the quality of information received. Based on these patterns, we suggest directions for model improvement and recommend user strategies for interacting with LLMs when seeking assistance with security.
OpenIPC is an open source operating system for IP cameras, offering an alternative to closed, insecure firmware. It provides freedom, control, and supports various features like cloud storage, streaming, and proxy usage.
Agentic AI is beginning to reshape malware detection and broader security operations. These systems are being used not to replace humans, but to take on the lower value jobs that have historically tied up analysts — from triaging alerts to reverse-engineering suspicious files.
The article discusses the emergence of 'agentic traffic' – outbound API calls made by autonomous AI agents – and the need for a new infrastructure layer, an 'AI Gateway', to govern and secure this traffic. It outlines the components of an AI Gateway and the importance of security, compliance, and observability in managing agentic AI.
This week's security roundup covers the Anubis web AI firewall, AI exploit generation, a vulnerability in CodeRabbit, the potential illegality of adblocking in Germany, a Microsoft Copilot audit log issue, and a disputed Elastic EDR vulnerability.
This Gist contains the system prompt for Claude Code, Anthropic's CLI for Claude. It details the tool's purpose, instructions for use, tone, proactive behavior, code style guidelines, task management, and references.
This article details significant security vulnerabilities found in the Model Context Protocol (MCP) ecosystem, a standardized interface for AI agents. It outlines six critical attack vectors – OAuth vulnerabilities, command injection, unrestricted network access, file system exposure, tool poisoning, and secret exposure – and explains how Docker MCP Toolkit provides enterprise-grade protection against these threats.
