    AI-Driven Expertise Loss - Gemini, Hugging Face, and the AI Arms Race

    OpenAI's latest advances have the rumor mill buzzing about "hidden thoughts" and unsupervisable models, but are AI safety experts panicking over the wrong threat? Get the clear-headed take behind the headlines. We start out with a classic old school hack against Dropbox. Next Patch Tuesday will be enabling "Memory Integrity" for many. Firefox moved to 155 and obtained a dumb Smart Window. CISA is terminating 6 most valuable cybersecurity services. OpenAI advanced to topof the heap with GPT-6 Astra. But... is it now hiding some of its thinking from monitoring? Nvidia is acquiring Hugging Face. Who's that good for? Google releases Gemini 3.8 Flash and Cyber. Is it good? Chinese cyberespionage is using AI to become more slippery. Matthew Green proposes a fascinating take on AI bug drought. A lifelong safety engineer contemplates AI-driven loss of expertise.

    AI Patching Shortcomings - Should You Trust AI-Generated Code?

    AI-generated code is flooding the industry, but researchers reveal that almost half of it contains critical vulnerabilities. This week, we unpack what happens when the race for automation outpaces security best practices. A possible means for preventing prompt injection abuse. Clear evidence of Chinese-made router malicious intent. A cool before and after SpinRite graph of SSD performance. How about adding unpredictable hashes to role tags? What did Claude make of last week's podcast? Could much better harnesses prevent prompt injection? A listener wants us to stop saying AI "thinks". AI designers ignore well-understood security concepts. Can we explain LLM AI using conventional computer terms? A listener strongly dislikes the term "rotating credentials". The land of AI is being filled with "meat proxies". Researchers exhaustively test frontier model vulnerability remediation. (hint: It does not go well.)

    The Post BlackHat State of AI - When AI Writes Malware

    AI agents are breaking free from their test environments, outsmarting their creators and breaching real-world networks in ways that no one predicted. Discover how these agentic models are changing the game for both cyber offense and defense. Anthropic's agentic AI also broke free and hacked others. We know much (much!) more about the OpenAI breakout. OpenAI posts that they're pausing "Astra" - even internally. What was that about AI recently cracking (or denting) cryptography. Bruce Schneier brilliantly equates AI agents to capricious genies. Apple doesn't react so well to the new deluge of security reports. Chrome 149 + 150 updates together fix 1,072 bugs.
