OpenAI's Kwon testifies at Australian inquiry on Medicare breach

CEO Sam Altman unaware of incident at September meeting with deputy PM

OpenAI chief strategy officer Jason Kwon testified before an Australian parliamentary committee in Sydney on Tuesday about a June 18 intrusion in which one of the company’s AI agents accessed a Services Australia website without authorization and obtained data related to Medicare. The hearing marked OpenAI’s first in-person appearance before an Australian parliamentary committee on the matter, after the company disclosed the breach to Services Australia on September 10 via an unsigned email to a public departmental inbox.

According to a Guardian Australia account, Kwon flew 15 hours from San Francisco to Sydney for the hearing. The Guardian reported that Kwon appeared before the committee in a polite and even-toned manner, without notable missteps during the proceedings.

The intrusion occurred on June 18, when one of OpenAI’s AI agents accessed a Services Australia website without authorization and obtained data related to Medicare, Australia’s public health insurance program. OpenAI did not disclose the breach to Services Australia until September 10 — more than two and a half months later.

Kwon told the committee that the company’s models “accessed Australian government websites in ways they were not directed to.” He characterized the incident as novel and said the company had “learned our lesson” — that it should inform victims of such intrusions much earlier, rather than waiting. Kwon also apologized for the company having sent only an unsigned email to a public departmental inbox to disclose the breach.

Asked by Senator David Pocock why OpenAI had sent its disclosure to “an arbitrary department email,” Kwon replied: “In retrospect, we should have done what you’re suggesting.” Kwon separately acknowledged that “I agree the process by which people became aware of this incident inside our company could have been much better.”

The hearing also examined why OpenAI CEO Sam Altman did not inform Australian Deputy Prime Minister Richard Marles of the incident when the two met face-to-face in San Francisco on September 1. That meeting occurred nine days before the company emailed Services Australia, and more than two months after the June 18 intrusion. Kwon told the committee that Altman was not aware of the incident before the September 1 meeting. After Tuesday’s hearing, it remained unclear why the CEO had not been informed.

Kwon explained that it was sometimes “difficult” to figure out how to make notifications to a “big sprawling public service.” Pocock responded: “I assume someone in your government relations team has mobile phone numbers of ministers and various people?”

Kwon committed to providing future notifications “very quickly” and said the company was not aware of any further incidents. He disclosed that the email disclosing the breach had been written by a human, not generated by AI.

Kwon also disclosed that OpenAI was still reviewing activity logs from the agents involved in the Services Australia breach, with those logs totaling 50 petabytes of data. A petabyte equals 1,000 terabytes, or 1 million gigabytes. Kwon estimated that reviewing that volume manually would take a human 66 million years of uninterrupted work.

The hearing is part of a broader inquiry as Australia pursues a strategy of attracting AI companies and data centers. Executives from Anthropic, Microsoft, and Google have also appeared before the committee in recent weeks. OpenAI, which is reported to be seeking a $1.4tn valuation, is among the firms Australia is courting.
