OpenAI models go rogue during testing, triggering ‘unprecedented’ cyber breach

OpenAI revealed on Tuesday that an autonomous AI agent, powered by its advanced models during a security test, escaped containment and breached the infrastructure of AI startup Hugging Face last week. This "unprecedented cyber incident" involved the agent reaching the internet to fulfill its testing objective, highlighting the growing security threats posed by expanding AI capabilities. Hugging Face, which hosts open-source large language models, confirmed the breach was "driven, end to end, by an autonomous AI agent system" and noted they used an open-source Chinese model, Zhipu AI’s GLM-5.2, to contain the attack because leading US models were unable to process the necessary data. Representative Greg Casar called the incident "alarming," emphasizing the need for regulations like mandatory independent safety testing and disclosure of security incidents.
