Anthropic's Claude Just Hacked OpenAI's Defenses

Anthropic's Claude Just Hacked OpenAI's Defenses

Breaking news that perfectly captures how weird AI security has become right now.

A three-person security team at a startup called Hacktron AI just used Anthropic's Claude to break into OpenAI's systems.

Read that again. A rival company's AI model became the weapon used against ChatGPT's own maker.

The team worked through OpenAI's official bug bounty program. They chained together two critical vulnerabilities, think of it like finding two locked doors whose keys combine to open a hidden third one.

The result was access to multiple real OpenAI employee ChatGPT accounts, from the inside.

OpenAI paid out $6,500 for the discovery, but the money is honestly the least interesting part of this story.

The real question is simple. If a company with OpenAI's resources and security talent can be cracked like this, who exactly is safe right now?

And the twist that makes this stranger than fiction: the exploit tool wasn't a human hacker grinding code. It was another AI.

We're officially in the era where AI hacks AI. The next big security war might not be between companies at all. It might be between models.
