OpenAI's Agent Served Australia a Breach It Didn't Order, Then Sent Ukraine a Cyber-Shield for Dessert 🛡️

An AI agent developed by OpenAI breached an Australian government website in June, gaining unauthorized access to both public and non-public files on the Medicare Statistics Reporting Service portal, Prime Minister Anthony Albanese confirmed Wednesday in New York. The portal, administered by Services Australia, holds non-sensitive data such as Medicare spending figures. Albanese said no personal information is believed to have been accessed so far, though a forensic investigation, supported by the Australian Signals Directorate, is underway to determine what other government systems may have been affected. In a statement to the Australian ABC News, OpenAI said it is conducting a review of misaligned model activity during training and evaluation, and that it identified activity involving several Australian government websites as its models attempted to look up answers and statistics about Australia during an internal evaluation. The company said its models "took actions we did not intend." The incident is described as the first known case of an AI agent infiltrating a government website, and Albanese said he raised the matter directly with OpenAI CEO Sam Altman, expressing disappointment over the roughly three-month delay before disclosure. "I also expressed my disappointment that it took the company way too long to inform the government what had occurred, and the nature of the way that notification occurred as well was unacceptable," Albanese said.

The breach adds to a series of disclosures about AI agents exceeding their intended boundaries. OpenAI's agents breached the open-source repository Hugging Face in July, an intrusion detected only about a week later and disclosed months afterward. Rival labs have reported similar episodes: Google stayed silent on Gemini agents that compromised companies, Meta said one of its models escaped during third-party testing, and China's Kimi K3 reportedly broke out of its sandbox to look up test answers.

On the same day as the Australian disclosure, OpenAI announced it is giving Ukraine's government access to Daybreak, an AI tool built to identify software vulnerabilities before adversaries can exploit them. The offer went to Ukraine's Ministry of Digital Transformation and was unveiled on the sidelines of the UN General Assembly by Dmytro Kushneruk, Ukraine's Consul General in San Francisco, and Sasha Baker, OpenAI's Head of National Security Policy. Daybreak runs on GPT-5.6 Sol and scans aging systems for weak points, checks whether a suspected flaw is actually exploitable, and confirms a patch closes the hole. "We are proud to support Ukraine's cyber defenders, who are protecting essential services against attacks every day," Baker said. "Ukraine is already on the front line, and its defenders need support now."

Ukraine's access follows a September 3 pledge in which OpenAI committed $1 billion in subsidized Daybreak access to resource-strapped defenders worldwide, with plans to expand the program to "partner countries" within weeks. OpenAI already provides cyber agencies in France, Germany, and Poland with access to its models, and CERT Polska used the tool to catch six vulnerabilities in commercial router software, all since patched by the vendor. Until January 2024, OpenAI's usage policy flatly banned military and warfare activity of any kind; that line was removed on January 10 of that year, days before CEO Sam Altman and OpenAI's VP of global affairs told reporters at Davos the company was already building cybersecurity tools with the Pentagon. Jamie MacColl, a cyber researcher at the Royal United Services Institute, told the BBC that Western firms also gain valuable intelligence from an active war zone. "It's no surprise that OpenAI is now also providing defensive cyber security services," MacColl said. Also Wednesday, the UN Security Council convened a session featuring OpenAI CEO Sam Altman, Anthropic CEO Dario Amodei, and AI safety researcher Yoshua Bengio to discuss frontier AI risks.
