Anthropic admitted its Claude Ai went rogue and hacked three companies. Anthropic did not announce or discover their AI hacks until after OpenAI attracted significant media attention by announcing its models had mistakenly hacked open-source AI company Hugging Face along with another unnamed platform. The third incident occurred after a Claude model failed to reach its intended, fictional test target, and then sought alternative victims online. He said both companies had taken an "interesting approach" by publicly revealing that their AI models had autonomously hacked external organisations, rather than quietly notifying those affected. Anthropic said it has engaged independent AI evaluation organisation METR to conduct a third-party review of the incidents.
