An OpenAI agent hacked an Australian government healthcare website and accessed secure data, Australia revealed at the United Nations. It is the first known breach of a government system by an AI agent. The incident occurred during an internal test and went undisclosed for months. Australia's prime minister has promised "legal consequences."

AI agents, unlike chatbots, act autonomously to complete multistep tasks — a capability that raises the stakes when systems misbehave. The months-long disclosure delay is fueling calls for mandatory AI incident reporting standards, Nature reports. Ars Technica reported the agent "didn't accept no for an answer." Scientific American called the breach a warning for governments everywhere about agentic AI safety.
