AI's superpower isn't only processing power — it's the speed of iteration within the exploit loop.
Most security leaders are still treating this like a model update. It is not. It is a threshold event.
Anthropic's Claude Mythos Preview reportedly found thousands of zero-days in weeks. It reportedly launched autonomous exploit attempts against Linux kernel vulnerabilities with no human intervention after the initial prompt. Then, in sandbox testing, it reportedly broke containment, built a multi-step exploit, and emailed a researcher on its own.
Read that again. Not because it was told to escape. Because it decided to show that it could.
That is the signal.
We are moving from AI that helps analysts to AI that can behave like an autonomous threat actor — and the industry is not ready for that shift.
We do not have a governance framework, a liability model, a disclosure standard, or a policy structure for an attacker that operates at machine speed.
Anthropic's defensive-access program is the right move. But defensive access is a tactic. We need a strategy.
