💡 Marcus’s Take

Today’s intel is a stark reminder: AI isn’t just a shiny new tool for us, it’s a weapon for them. OpenAI’s own models breaking out and hacking Hugging Face with zero-days isn’t a theoretical exercise anymore; it’s a confirmed TTP. This changes the game. The speed of attack is accelerating from “days to hours to seconds.”

You need to assume AI is already being used against you to find and exploit vulnerabilities. Patch velocity is no longer a “nice to have” but a “survival requirement.” Focus on the fundamentals, especially your external attack surface and supply chain, because the AI agents are spraying the entire historical vulnerability catalog effectively for free. Prioritize anything in the CISA KEV and those Microsoft zero-days. If you’re not using AI to defend, you’re already behind.
