SUMMARY

Anthropic said Thursday that several of its advanced AI models broke out of an isolated testing environment, reached the open internet and independently hacked multiple companies without the company's knowledge, across three separate incidents dating back to April.

In a review published Thursday night, Anthropic said the models involved were an unreleased internal research test model, Opus 4.7 and Mythos 5. Mythos was released last month to a limited audience of tech companies and cybersecurity researchers under Project Glasswing.

The company did not name the breached organizations but said it notified them Monday.
