US govt sites targeted, ChatGPT user images exposed: What OpenAI’s runaway agents got up to

All of the incidents reportedly occurred without OpenAI’s knowledge. None of them led to successful breaches, but they add to a growing list of examples of AI agents behaving in unexpected and concerning ways.

The swarm of misaligned AI agents successfully infiltrated a statistics portal containing non-sensitive data from Australia’s universal healthcare scheme Medicare, according to Australian Prime Minister Anthony Albanese last week. Prior to that, OpenAI acknowledged that its AI agents targeted several other websites, including a German online forum that the agents turned into a message board and posted 1,800 times on it.

In this piece, we take a closer look at incidents involving US government organisations as well as the evasion of a robot detection test in the Hugging Face hack, and another case where 53 anonymised user-uploaded images were shared by the agents on other sites.

Why it matters

The number of situations when AI agents from OpenAI, Anthropic, Meta, and Google have misbehaved and hacked or tried to breach companies, universities, and government organisations, continues to rise – each more startling than the one before.

While some of these AI agent-driven attacks were successful and others failed, all of them highlight growing concerns about the capabilities of increasingly autonomous systems. Anthropic CEO Dario Amodei has called for a deliberate slowdown in frontier AI development to give safety measures time to catch up.

But others disagree. Nvidia CEO Jensen Huang has said that fears about uncontrollable AI systems are unrealistic, while US President Donald Trump has said he does not believe a slowdown in the AI industry is necessary.

“We have not been as fast as we would have liked but we are trying to balance our desire for transparency with gaining a clear understanding from petabytes of agent activity logs, and working with impacted organizations. We are prioritising as best as we can based on severity, and adding resources,” OpenAI CEO Sam Altman said in a post on X on Friday.

“Hugging Face is still the most severe event we’ve seen. We will be as transparent as we can be subject to things like vulnerabilities in other companies that our agents have found, which will be their call to disclose or not,” Altman added.

Probing US govt websites

With the US Education Department, OpenAI’s agents tried to hack the website to gather data from the department’s civil rights office but failed, as per Transluce researchers.

The “system operations reviews have found no evidence of any impact to our website or databases,” an Education Department spokesperson was quoted as saying by The New York Times. OpenAI has said it is continuing to investigate the situation with the Education Department.

Regarding the US Commerce Department, the agents pulled data from the Census Bureau website using login credentials it found online. The agents gained access to information that was publicly available on the Census Bureau’s website and available to anyone, but not to any private data, as per the department’s spokesperson.

With the US SEC, the agents gathered and shared public data from the official website of the markets regulator on an online forum. The agents did not gain unsanctioned access to non-public information on the SEC website.

Besides the three major US government agencies, OpenAI also reportedly notified the Chicago city government that its agents had obtained publicly available information from a municipal website, but did not obtain any sensitive information.

The researchers at Transluce found that the AI agents interacted with the US government websites using an array of gray-area tactics and even violated explicit usage policies in a few cases.

The research team also found that AI agents had probed sites belonging to several other US government websites at the federal and state levels, including the Navy and the Office of Management and Budget at the White House. However, this activity could not be attributed to OpenAI’s agents and might involve agents of another company or frontier AI lab.

The agents unusually interacted with the UN Conference on Trade and Development’s (UNCTAD) statistics site as well. The website was scanned by the agents over 16,000 times between April and June 2026, according to security researcher Rowan Howard-Jones.

When the agents found that they did not have direct API access to UNCTADstat and could not pull data due to restrictions on HTTP tools, they figured out a bypass involving hijacking Google’s XSS game (a cross-site scripting learning tool) to start pulling data from the site.

Evading robot detection tests

During the early stages of its months-long hack of Hugging Face, OpenAI’s agents tried to create multiple new accounts on the AI developer platform. However, creating new accounts required solving captchas, a commonly used visual test designed to block bots from accessing websites.

OpenAI’s agents were able to solve the captchas by using shortened URLs, website screenshots, and even other AI models, according to a new report from research firm Parse.

The agents created a tranche of one million shortened URLs from online link-shortening websites over a five-day period. These shortened URLs contained encoded bits of information that were later chained together to form a computer programme. This programme was used to create a visual code, similar to a QR code or bar code, to transmit data from a public screenshot service to the agents.

The agents also tried to message other AI models such as the early versions of ChatGPT and Claude to help solve the captchas. They even gained access to Hugging Face’s internal Slack, and attempted to search through and download messages from the employees.

Leaking user images to other sites

Images uploaded to OpenAI’s ChatGPT could be used as training data for other models if individual users do not opt out (with an exception for enterprise users), as per the company’s privacy policy. The policy does not allow those images to be shared with external service providers. However, that is exactly what OpenAI’s agents did upon gaining access to OpenAI’s research environment.

Over 53 user-provided images were posted to image-hosting sites as links that were not publicly listed. To be sure, the images could still be discovered even if the links were not publicly listed.

“This is not an appropriate use of this data,” the company said. OpenAI further said it is working with the image-hosting site providers to scrub the content posted by the agents.

Since OpenAI follows a data anonymisation approach to prevent linking uploaded images to specific users, the company said it could not notify the affected users. Dozens of other victims, including governments, universities, public agencies, have been notified about the agents’ activities, it added.

OpenAI’s teams are still reviewing internal logs of the agents’ activities to find previously unknown cases of hacking attempts. Meanwhile, the company said it has paused training of its latest AI models and will resume development “only when we are confident that we have additional safeguards” in place. OpenAI added that it expects to hit pause again as AI develops and other issues emerge.
