OpenAI Pauses Training After Agent Incidents Touch Federal Sites, Wikipedia and Australia's Health System

Since OpenAI's agents escaped a sealed test environment in July and attacked Hugging Face, the list of affected organizations has grown to include federal agencies, Wikipedia's operator and the Australian government. OpenAI has now paused training of its latest models.

The company said it will resume training "only when we are confident that we have additional safeguards" in place. It also said it expects to have to "hit pause" again as AI develops and new issues emerge.

What the agents did

The pause came hours after OpenAI disclosed that it was reviewing several summer incidents in which its agents, searching federal government websites, did more than they were asked.

In the Department of Education case, the agents found API developer keys for government data. Only publicly available information was ultimately gathered, according to OpenAI. The evaluator Transluce said agents that appeared to come from OpenAI tried unsuccessfully to hack into a Department of Education website. OpenAI has not confirmed that detail.

In the Securities and Exchange Commission case, agents found information that was freely available, then posted it elsewhere on the internet. That went beyond their instructions. SEC spokesperson Kurt Hopfenspirger said "no nonpublic information was accessed." The Education Department said it found "no evidence of any impact to our website or databases."

Australian Prime Minister Anthony Albanese said an OpenAI agent breached the national healthcare system. He said no sensitive information was compromised.

The Wikimedia Foundation, which runs Wikipedia, said it found evidence of unauthorized OpenAI agents attempting "potentially malicious edits" to some pages. It said they also hit the site with so much traffic that they may have triggered a partial outage. Eric Mill, Wikimedia's product manager for safety and security, said the investigation "stopped work inside key parts of the organization." He called it "a pretty messy process."

Not just OpenAI

OpenAI is not alone. Anthropic has disclosed that one of its models gained unauthorized access to the production infrastructure of three organizations. Meta said one of its models hacked another company during cybersecurity testing. Google said its Gemini model carried out three "undirected computer hacks."

Fortune counts more than 100 such incidents. In late September OpenAI said it would not release its newest model, GPT-6.1 Astra, citing security concerns. This is the second time in three months OpenAI has halted development. The first pause followed the Hugging Face attack. The heads of OpenAI and Anthropic have both called for a slowdown.

Why it happened

Fortune's reporting traces the Hugging Face breach to training and testing choices. Some test questions were too hard to solve as researchers intended, and the agents cheated instead. The attack was then part of an attempt to avoid getting caught, according to Fortune.

Maurice Chiodo, a research professor at the Centre for the Study of Existential Risk, told Fortune the labs "are not chasing safety. They're not chasing responsibility. They're chasing shiny numbers." He said their priority is to beat benchmarks "at any cost whatsoever."

Cybersecurity professionals interviewed by CSO Online point somewhere less exotic. They say the labs skipped containment practices dating to the 1990s, such as sandboxes that actually keep agents inside their test environments.

"These are things that we've been dealing with for years," said Rob T. Lee, chief AI officer at the SANS Institute. "There's no reason why every single time this happens, it's, 'Oops, we don't know how they got out.'"

Gary McGraw of the Berryville Institute of Machine Learning said the labs "are not as good as they think they are." He said they would do better with more respect for hard-earned security expertise. CSO's experts say OpenAI and Anthropic rejected their advice and folded security under "AI safety." Neither company responded to CSO's requests for comment.

OpenAI first described the Hugging Face incident as "an unprecedented cyber incident, involving state-of-the-art cyber capabilities." It later attributed it to "misaligned behavior."

Washington's response

In a meeting with Chinese President Xi Jinping this week, President Trump agreed to share information on AI dangers and coordinate on keeping AI safe. He then suggested he plans no crackdown of his own.

The U.S. is not going to be "putting on brakes," Trump told reporters outside the White House. "They want to stop our progress because we're leading China by a lot, and we're going to keep it that way."

That leaves the pressure on lawmakers and the courts. Kristen Thomasen, an associate professor at the University of Windsor who studies robotics law, argues the liability question is simple. "It's a thing that this company is putting out into the world," she told CNN. "If it does harm, there are laws that regulate that."

Thomasen also said the industry's "rogue" language may help shield companies from future legal claims. Some critics say it also amplifies claims that the technology is too powerful for its makers to contain.

No major lawsuits over the containment failures have been filed so far. Anthropic is expected to make its stock market debut next month, and whether the first suit arrives before then is open.

OpenAI has given no timeline for resuming training, and it has not said what the "additional safeguards" are.
