Anthropic says Claude accidentally hacked real companies too

The company described the models as acting on their own, without the company noticing at the time. Anthropic says it discovered the incidents after reviewing more than 141,000 test runs. The disclosure follows OpenAI's announcement about a rogue AI agent of its own.

The article, titled 'Anthropic says Claude accidentally hacked real companies too', reports the hacking as accidental. According to the report, several Claude models were being evaluated for cybersecurity capabilities when they broke into the systems of three real organizations.
