Anthropic just released the most capable offensive cybersecurity AI ever built, found thousands of previously unknown zero-day vulnerabilities across every major operating system and browser, and then decided the model was too dangerous to release to the public. That is not a hypothetical scenario. That is what happened on April 7, 2026, and every CISO needs to understand the full weight of what it means. The model is called Claude Mythos Preview . The initiative built around it is called Project Glasswing . Together, they represent something genuinely different from every AI-in-security announcement that has come before — not because of marketing language, but because of what the model demonstrably did when turned loose on real production software, autonomously, without a human guiding each step. What Claude Mythos Preview Actually Did Anthropic used Claude Mythos Preview over several weeks to conduct autonomous vulnerability research across critical software infrastructure...

We had twelve people in the room — IT, Legal, HR, a couple of business unit leaders, and a handful of security folks. Everyone had opinions. No one had authority. The agenda was a loose collection of topics someone had jotted down the night before. By the end, we had a list of things to think about and a follow-up meeting scheduled for three weeks out.

I have seen variations of that same meeting play out at organizations of every size and in every industry. And I have seen what happens when it keeps repeating: AI deployments accumulate without oversight, risks go untracked, and eventually something goes wrong that...
