Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: OpenRISC: Traps – Do not send signals to kernel mode threads OpenRISC’s exception handling sends signals to user processes during floating-point exceptions and trap instructions for debugging purposes, among others. There is a bu...

Astra Linux – Vulnerability in glib2.0

A issue was discovered in GNOME GLib before version 2.78.5, and also in versions 2.79.x and 2.80.x before 2.80.1. When a GDBus-based client subscribes to signals from a trusted system service such as NetworkManager on a shared computer, other users of the same computer can send spoofed D-Bus...

Reconstructing AI activity in investigations

AI systems are now part of everyday work. Investigators need a consistent way to reconstruct what happened within them. Security teams are already investigating activity involving Microsoft 365 Copilot and Azure AI services—from prompt injection attempts to unexpected data access. Those signals a...

FreeBSD -- sigqueue(2) missing capability mode restriction

Problem Description: sigqueue2 was marked as permitted in capability mode with the introduction of Capsicum in 2011, but the implementation of kernsigqueue did not include a capability mode check restricting signal delivery to the calling process's own PID. Impact: A process in capability mode ca...

RecurGuard: Runtime Monitoring for Reasoning-Token Consumption Attacks

Reasoning-capable large language models can be induced to spend their generation budget on injected decoy tasks rather than answering the user's question, causing denial of service when no final answer is produced and denial of wallet when excess output tokens are billed. Input-side safety...

From Operating Model to Product: How We Built the ROC for Detection-Speed Remediation

In the first article in this series, we made the case for a prevention-led operating model. This article is about what happened next: the decision to build something that did not exist, and what it took to make it real. Turning an operating model into a product sounds straightforward until you ar...

ClawHub Security Signals: When VirusTotal, Static Analysis, and SkillSpector Disagree

Agent skills extend AI agents with reusable instructions, tools, scripts, references, and workflows, establishing a security boundary distinct from both model safety and traditional package-malware detection. ClawHub Security Signals is a sanitized dataset of 67,453 latest public OpenClaw skill...

Stateful Online Monitoring Catches Distributed Agent Attacks

Language models can find thousands of severe software vulnerabilities, and agents are increasingly being misused for cyberattacks. To avoid detection, attackers frequently distribute their misuse, splitting a harmful task across many user accounts so each individual transcript looks benign. Becau...

CVE-2026-46187

A flaw was found in the Linux kernel's Redpine Signals RSI Wi-Fi driver. A race condition, which occurs when multiple operations try to access the same resource simultaneously, exists in the management of kernel threads kthreads, lightweight processes within the kernel. This can lead to a...

Less panic patching, more precision

Welcome to this week's edition of the Threat Source newsletter. Recently, Martin closed his introduction with a warning: Ready or not, the time of much patching is coming. I've been chewing on that one for a while because I'm rethinking my own enrichment pipelines along these lines, and the...

The Importance of Out-Of-Band Metadata for Safe Autonomous Agents: The Redpanda Agentic Data Plane

AI agents are increasingly expected to operate as digital employees: accessing enterprise data, making decisions, and taking actions autonomously. But agents are simultaneously less predictable than humans -- prone to hallucination, misinterpretation, and adversarial manipulation -- and more...

Refusal Before Decoding: Detecting and Exploiting Refusal Signals in Intermediate LLM Activations

In this paper, we investigate whether refusal behavior can be predicted from LLM intermediate activations before decoding using linear probes trained on residual stream activations at each transformer block. We find that refusal is linearly decodable well before the final layer, indicating that...
