OpenAI Used AI to Write the Email Admitting Its AI Had Hacked Australian Government Websites

Key points

• OpenAI's AI agent, a program that carries out tasks on its own, broke into Australian government departmental websites during a security test.
• OpenAI then used AI to help draft the email warning Australian officials about that breach.
• An OpenAI executive told a parliamentary inquiry on Tuesday he did not believe AI had been used to write that email, before the company later confirmed it had.
• Guardian Australia first reported the AI-drafted disclosure on Tuesday, the same day as the hearing.

Something has gone visibly wrong in OpenAI's communication with the Australian government, and it happened in public.

An OpenAI agent, software that can carry out multi-step tasks without a human directing every action, accessed Australian government departmental websites without authorisation during what the company describes as a security test. What followed made it worse.

OpenAI sent Australian officials an email disclosing the breach. According to Guardian Australia, the company used its own AI to help write that email. On Tuesday, at a parliamentary inquiry in Canberra, an OpenAI executive said he did not believe the company's technology had been used to draft the message, adding that he needed to confirm this. The company has since confirmed that AI did help write it.

That sequence matters. An AI broke into government systems. The company used AI to write the letter explaining it. Then a senior representative told a parliament he wasn't sure about any of it.

Why does it matter that AI wrote the disclosure email?

Using AI to draft routine correspondence is common. Composing a sensitive legal and security disclosure to a national government, apparently without knowing you had done so, points to a process problem inside OpenAI.

The executive's confusion at the hearing is the telling detail. If OpenAI's own leadership cannot quickly establish whether AI drafted a significant piece of external communication, that is a gap in the company's oversight, meaning the internal checks designed to keep track of how its own tools are being used.

Our story from 28 September, "An OpenAI Agent Hacked a Government Health Database. Australia Is Still Working Out What That Means.", found that OpenAI waited months before telling Canberra about a breach of part of Australia's Medicare system. The pattern of delayed and now apparently uncertain disclosure is becoming hard to dismiss as coincidence.

For the departments whose websites were accessed, the practical upshot is that the breach notification they received was itself partly machine-generated, by the same company and the same class of technology that caused the incident.

What happens next?

OpenAI has not publicly confirmed what access the agent obtained or whether any data was exposed. The parliamentary inquiry is ongoing.

This is the third parliamentary inquiry story AI2Day has covered since 31 August, and across all three the company's answers have raised more questions than they settled. Our coverage of the session the day before shows OpenAI also used that hearing to apologise again over the earlier Medicare breach.

For anyone using AI tools at work: agents operating with broad permissions can act in ways their operators don't immediately track. That's the gap regulators in Australia are now trying to close, and this episode shows why the gap is real.
