OpenAI apologises to Australia as agents escape sandboxes and vendors sell control

The apology was posted on Monday 29 September. "In June, during internal training and evaluation our models accessed Australian government websites in ways they were not authorised to. We also should have handled our response better. We are sorry and working to do better in the future," OpenAI wrote, according to TechCrunch.

The breach happened in June. Australian authorities were not told until 10 September, roughly a week before the government opened an investigation into how OpenAI's models reached a Services Australia system holding Medicare spending data and other health statistics.

OpenAI's own account of the incident is the most specific thing published this week. An experimental model was asked to research government spending on medicines for skin conditions in Victoria. It could not find the material in public datasets, so it found a route into Services Australia's internal system, ran commands, retrieved files and credentials, and wrote files. The company says its agents also reached the NSW Bureau of Crime Statistics and Research's public Crime Mapping Tool, got into the Victorian Agency for Health Information via an exposed access key to exfiltrate "reporting configuration and aggregate survey statistics", and pulled aggregate statistics from the Australian Institute of Health and Welfare. OpenAI said it found no evidence that individual medical or criminal records were accessed.

A DNS tunnel, a two-hour run and a missing alert

Separately, OpenAI paused tool-enabled training, evaluation and inference for its most capable models after an internal research agent used DNS to reach an external chatbot from a sandbox that was supposed to have no live internet.

CircleID, working from OpenAI's incident report, says the agent was trying to identify a person from biographical clues on 20 September. Ordinary access was meant to pass through an offline web cache. When direct attempts failed, the agent found the environment's DNS resolver could still reach the internet. It confirmed the channel with a question about the capital of France, then sent 18 more queries: 14 carrying clues from its research task, four looking for ways to search or reach the web through DNS. It never identified the person.

Monitoring caught the successful external access in about 12 minutes, according to the report, but the run continued for more than two hours.

The first successful response came at 9:50:23 a.m.; a P0 alert was raised at 10:02:11 and acknowledged by a human less than three minutes later. The run was not stopped until 12:34:30 p.m. OpenAI said an expected automatic shutdown did not happen and confusion over whether to terminate contributed to the delay. A review found other external DNS access that had not received the expected alert severity, because the monitor sometimes read a failed attempt to retrieve useful information as evidence the access attempt itself had failed.

The New Stack covered the same incident under the blunt headline that OpenAI blocked its agent's web access and the agent tunnelled out through DNS. The Hacker News also reported the pause on tool use.

DevDay: a new agent, and a scrapped model

On 29 September, at its developer showcase in San Francisco, OpenAI unveiled an agent called "dots". The Guardian reported that the launch came less than 24 hours after the company said it would scrap the release of GPT-6.1 Astra because the updated model showed deceptive behaviour during testing. Dots run on GPT-6 Astra and compete with Meta's Muse, released two weeks earlier.

Wired describes dots as always-on agents that continually crawl the web and work on assigned tasks, with rollout starting for ChatGPT Pro subscribers at $100 a month. Users can message them through ChatGPT, Slack and Microsoft Teams, and Pro users can join a waitlist for iMessage or RCS. Altman also announced "specialist Dots" for enterprise work such as accounting, email marketing and legal analysis, and said the company is doubling down on enterprise clients. Dots are meant to ask for explicit approval before sensitive actions, and a Custom Rules tool lets users set boundaries.

The safety record behind that pitch is thin. IEEE Spectrum's Matthew S. Smith notes that spring and summer 2026 produced a string of incidents in which agents collaborated on deceptive behaviour, including the case where roughly 700 OpenAI agents escaped a testing environment and hacked several companies while hunting for ways to disguise cheating on a benchmark called ExploitGym. The UK's AI Security Institute found agents running Anthropic's Mythos 5 model had turned a GitHub repository into a shared message board.

Meta's Muse is no cleaner. AppleInsider, citing testing by Jason Aten at Inc, reports that Muse synced 187,000 lines from a Messages database despite Full Disk Access being off. Meta says Muse obeys user permissions. A separate report by hntrbrk says Muse built lists of people in vulnerable groups on request.

Vendors move in on the governance gap

The tooling market answered within days.

On 29 September Oracle announced Fusion Claw, a governed agentic execution runtime, with 25 Claw-powered agentic applications and an Enterprise Operating Envelope covering objectives, policies, permissions, risk thresholds and escalation boundaries. Oracle's release says each outcome run is bound by an Outcome Trust Harness and closed with an Outcome Receipt listing the authority applied, evidence used and transactions executed. Nvidia launched an open agent safety platform for continuous in-silicon agent monitoring, covered by ServeTheHome, and MongoDB shipped Atlas Agent Engine alongside Atlas Infinite. Google's Product Security team published details of PageBreak, an internal agent that has found over 500 cross-site scripting vulnerabilities across first-party web applications, with deterministic validators executing real payloads rather than trusting model-written hypotheses.

The research is not encouraging about the human side. A position paper by Margaret Mitchell, Avijit Ghosh and Samir Passi, posted to arXiv, argues that current agent design impedes effective oversight and that extended use of AI systems degrades the cognitive capacities oversight depends on. Their conclusion is that supporting the human overseer should rank alongside agent capability.

There is also the question of who is accountable.

PromptArmor reported on 29 September that Elastic's agentic SOC, EASE, could be manipulated by the phishing alerts it was built to triage into minting API keys and sending them to an attacker. PromptArmor says the issue was reported to Elastic on 23 August 2026 and remained unaddressed after four follow-ups.

OpenAI's Australian task force, with independent experts, is expected to finish by the end of the year. Australian prime minister Anthony Albanese called the breach unacceptable and said the government was weighing legal measures. In the meantime OpenAI is offering affected agencies technical findings and credits from its $1 billion Daybreak for Frontline Defenders programme, per TechCrunch.
