    Deep Dive: ARTEX: The FBI's Warning About AI Agents That Run the Whole Intrusion

    The FBI's November 13, 2026 FLASH warns that ARTEX, an open-source agentic AI penetration testing framework, is being used to go from first scan to privileged access in under three hours. How it works, the South Korea and ConnectWise campaigns, the intrusion chain, what to look for in your logs, the FBI's mitigations and three things to do today. In this deep dive What ARTEX is: a Go orchestrator that hands an intrusion to AI agents, and why pulling the GitHub repo on October 8 didn't stop it How it works: SI agents in parallel, reasoning rented from Claude, GPT, DeepSeek, GLM, Grok or Kimi, often through API resellers The FBI's five risks, from multi-target operations to a compressed detection window Two campaigns: about 67,000 people's data from South Korean financial institutions, and 2,250+ tenants reached through ConnectWise Cloud Backup's OAuth app The intrusion chain, the lateral movement EDR blocked, and why the initial access flaws were all testable Indicators and three places to detect it: identity, egress to LLM APIs, and the cloud control plane The FBI's mitigations, what it means for Security+, CySA+ and SecAI+, and three actions for today Source: FBI FLASH-20261113-001, "Threat Overview of ARTEX Autonomous Penetration Testing Framework," November 13, 2026 (TLP:CLEAR).

    Deep Dive: CrowdStrike, July 2024: Backout, Fail Forward and the Size of the Blast Radius

    What the July 2024 CrowdStrike update teaches about recovery, why a fast revert didn't help machines that had already crashed, and how to choose between backing out and failing forward. From Domain 1, General Security Concepts, of Chris's new CompTIA Security+ (SY0-801) course on Pluralsight. In this deep dive July 19th, 2024: a routine CrowdStrike content update sends Windows machines running the sensor into a crash loop Why reverting 78 minutes later only protected machines that hadn't crashed yet, and how BitLocker recovery keys stretched recovery into days The staged rollout CrowdStrike moved to: a canary group, early adopters, broad deployment, then everyone When backing out is the safer choice, and when failing forward makes more sense Finding the point of no return before the change starts This segment is from Domain 1, General Security Concepts, of Chris's new CompTIA Security+ (SY0-801) course on Pluralsight.

    AI Security Brief: GPT-6 Cyber Builds 948 Linux Exploits, Claude Code Leaks Secrets to GitHub

    An AI model builds hundreds of Linux exploits, Claude Code leaks secrets to GitHub, and stolen AI keys push a bad plugin to 5,000 companies. In this episode GPT-6 Cyber builds 948 Linux exploits while fixes lag: AI is finding serious bugs in mature code faster than the industry is patching them. Claude Code's 'don't ask again' leaks secrets to GitHub: Approved commands, passwords included, are being saved to settings files and pushed to public repos. Stolen AI keys chain into a plugin hitting 5,000 companies: A breach at one AI provider rippled through a coding tool into thousands of customers. Researchers bypass ChatGPT Lockdown Mode: A protection built to stop prompt injection exfiltration was sidestepped before it was patched. Claude Code hooks see the checkpoint, not what follows: Agent policy controls judge the request, not the processes and connections it spawns afterward. Prompt adware hides in a Codex jailbreak bundle: A jailbreak rewrites an agent's trusted instructions, proving agent config files are an attack surface. White House AI accord leaves auditors undefined: 'Independently audited' has no shared definition, so customers have to ask the follow-up questions. What to do this week Hunt for leaked agent secrets. Scan repos for Claude Code settings files and rotate any keys or passwords you find. Look past the hook checkpoint. Back agent hooks with endpoint monitoring and track changes to agent config files. Get your patch process ready. AI is finding bugs faster than teams fix them. Plan capacity for a bigger patch queue.
