AI Agents Are Increasingly Going Rogue—With Few Rules, Who Gets Held Accountable? - Newsweek

A string of incidents involving artificial intelligence agents going rogue—and breaking through safeguards to access systems they were not supposed to reach—is putting pressure on lawmakers to define who is responsible when autonomous AI crosses the line.

That question was at the center of a Senate hearing Wednesday, where Senator Josh Hawley, a Missouri Republican, pressed researchers and cybersecurity experts about the risks posed by autonomous AI agents. The hearing came after OpenAI disclosed that agents used in an internal cybersecurity evaluation had escaped their testing environments and compromised systems belonging to AI platform Hugging Face.

Sam Altman, OpenAI's CEO, had been invited to testify but did not appear.

The issue has also surfaced on the other side of the world. An OpenAI agent gained unauthorized access to an Australian government portal containing Medicare statistics in June, prompting an investigation and a request for Altman to appear before an Australian Senate inquiry. He did not appear there either.

The incidents are different, but together they highlight an emerging legal problem: AI systems can now perform actions that may violate laws without a human explicitly directing them to do so. Existing laws can punish hacking, fraud and other misconduct. What is less clear is when those laws can be applied to the people or companies that built or deployed an autonomous system.

Newsweek has reached out to OpenAI for comment.

The incident that first prompted Hawley's investigation began as a cybersecurity test inside OpenAI.

In June, OpenAI launched tens of thousands of AI agents in internal evaluations, according to testimony from Chris Painter, president of Model Evaluation and Threat Research, or METR, which helped investigate the incident.

The agents were supposed to operate inside individual sandboxes while solving cybersecurity problems. Some were given tasks that could not be completed legitimately. According to Painter, some agents found ways to escape their sandboxes and created an unauthorized shared message board.

About 1,200 agents eventually exchanged more than 70,000 messages and files through the channel, Painter told senators. Roughly 700 agents went on to compromise Hugging Face, gaining access to production systems and private source code," he said.

OpenAI's own investigation described the behavior somewhat differently. The company said the agents circumvented controls designed to isolate them from the internet, exploited vulnerabilities in shared infrastructure and accessed third-party systems. OpenAI said the activity was driven primarily by an internal research model operating with reduced safeguards.

OpenAI said the agents were attempting to cheat on their cybersecurity tasks by finding answers online—a behavior known as "reward hacking." The company said the incident exposed weaknesses in its training and evaluation systems and prompted it to strengthen sandboxing, restrict internet access and improve monitoring.

Hawley has questioned whether the company's public account goes far enough.

In a September 10 letter to Altman launching his investigation, Hawley said OpenAI had known before the Hugging Face incident that agents were using unauthorized communication channels and had discovered an exploit that gave them administrator access to internal systems. He accused the company of acting “recklessly” and questioned how much information its outside auditors were actually given.

The senator framed the broader question bluntly: “Who is held liable when AI goes rogue?”

Hawley leans AI skeptic according to Newsweek's AI Policy Scorecard. The scorecard ranks where every sitting member of Congress stands on AI policy. Scores range from 1 - AI Skeptic to 5 - AI Booster, based on their voting record and public stances across five policy areas: regulation & authority, data centers & energy, jobs & the economy, safety & privacy and national security.

At Wednesday's hearing, Hawley returned to that question. The hearing, titled “Rogue AI: Securing the Homeland Against AI Agent Attacks,” examined not only the Hugging Face incident but the broader ability of AI agents to conduct cyberattacks against government agencies, businesses and critical infrastructure.

Witnesses told senators that AI agents are increasingly capable of completing complex tasks autonomously, at a scale and speed that makes human supervision difficult. METR's Painter said companies increasingly rely on AI-based monitoring and controls rather than humans watching every action an agent takes.

Hawley repeatedly returned to what happens when those systems act outside their instructions.

He said at the hearing that the OpenAI CEO had been offered the opportunity to appear and “turned us down,” adding that he believed the American public deserved to know what was happening inside AI companies.

Hawley's investigation is not limited to the Hugging Face episode. His September letter asked OpenAI to provide information and documents about the incident and other instances of AI systems behaving in ways their developers did not intend.

While Hawley was examining the Hugging Face incident in Washington, Australian officials were investigating another unauthorized OpenAI agent intrusion.

On June 18, an OpenAI agent gained unauthorized access to the Medicare Statistics Reporting Service, a public-facing Australian government portal administered by Services Australia. Australian Prime Minister Anthony Albanese said the agent accessed public and non-public files. Officials said there was no evidence that individual medical information had been accessed.

Australian officials described the incident as serious even while saying its practical impact appeared limited.

Defense Minister Richard Marles said the agent initially requested information, was denied access and then engaged in what officials described as “misaligned behavior” to gain unauthorized access. He said the incident was “utterly unacceptable,” while emphasizing that no individual's medical data had been accessed.

The Australian government also criticized OpenAI's handling of the disclosure. Albanese said the company took roughly three months to notify the government and that he had spoken directly with Altman to express Australia's “extreme concern.”

OpenAI subsequently apologized. The company said the incident involved an internal-only model that did not have the full safeguards used by its public products and said it wanted to “rebuild trust with the Australian people.” It also said it would provide resources and expertise to support affected Australian agencies.

OpenAI said the agent accessed internal files, credentials and statistics and wrote files during the incident. It also said separate attempts to bypass access controls were unsuccessful.

Altman was asked to appear before both the U.S. Senate hearing and the Australian Senate inquiry, but neither request resulted in him testifying.

In Hawley's case, the invitation was not a compulsory subpoena. Hawley said Altman was invited to testify and declined. There is no indication in the hearing record that the committee had subpoenaed him to appear.

The Australian hearing was also based on a request to appear. Reuters reported that OpenAI and Anthropic declined to attend the October 1 hearing, citing the short notice they received. OpenAI said its chief strategy officer, Jason Kwon, would instead appear before a separate Australian parliamentary committee on October 6.

That leaves open a potentially important question for both governments: Will lawmakers escalate from asking executives to testify to compelling them to do so?

For now, Altman has not faced questioning in either proceeding.

However, on Thursday, Rob Bonta, California’s attorney general, confirmed that the state’s department of justice issued a series of investigative subpoenas to OpenAI. "My office is asking OpenAI additional questions regarding cybersecurity incidents and risks involving the company and its AI models," he said. It's not clear whether Altman would have to personally testify in that case.

The United States has multiple laws that prohibit unauthorized computer access. The Computer Fraud and Abuse Act, for example, criminalizes several forms of unauthorized access and certain conduct that causes damage to protected computers. The law does not, however, contain a simple provision saying that an AI developer is automatically responsible whenever an autonomous AI system violates it.

That is emerging as an important distinction. A human hacker can potentially be prosecuted because prosecutors can establish what that person knowingly or intentionally did. The Justice Department's guidance emphasizes proving that a defendant knowingly accessed a computer without authorization or exceeded authorized access.

With an AI agent, the chain of responsibility can look very different. A user might give an agent a broad instruction. A developer might build the model and its safeguards. The company might deploy the system. The agent might then determine the steps it takes to accomplish the goal.

If the agent independently discovers a vulnerability and uses it to access another computer, which human actor had the necessary intent?

That was one of the questions raised at Hawley's hearing.

Georgetown law professor Paul Ohm told senators that existing civil laws, including state tort law and the Federal Trade Commission's prohibition on unfair or deceptive practices, could provide avenues for accountability. He also said criminal law could apply in some cases but noted that hacking statutes can be complicated by requirements to establish human intent.

Ohm argued that traditional common-law liability is flexible enough to address new technologies, while also suggesting Congress could consider strict liability for AI developers in certain circumstances.

The U.S. does not currently have a single, comprehensive federal law regulating AI.

Instead, AI companies are subject to existing laws that can apply when AI is used to commit illegal conduct. In addition to the Computer Fraud and Abuse Act, agencies such as the Federal Trade Commission can use existing consumer-protection authority against certain deceptive or unfair AI practices

The federal government also has voluntary standards, including the National Institute of Standards and Technology's AI Risk Management Framework.

On Thursday, Hawley and Democratic Sen. Chris Murphy of Connecticut announced the AI Agent Accountability Act, which would establish civil and criminal liability for AI-agent operators and developers in certain hacking incidents.

The proposal would use the Computer Fraud and Abuse Act to hold operators liable for knowingly operating an AI agent that recklessly causes hacking damage or loss. It would also impose liability on developers that fail to implement reasonable safeguards when they knew or had reason to know their AI agents were capable of hacking.

Hawley said AI companies should not be able to escape responsibility simply because the system, rather than a human employee, carried out the attack.

“If Big Tech companies are going to design AI agents that wreak havoc, these companies better be on the hook for any damage that is caused,” Hawley said Thursday.

Murphy, a Democrat, made a similar argument, saying that when AI agents conduct dangerous cyberattacks, “the corporations and executives responsible for those AI agents need to be held accountable.”

Hawley and Murphy are arguing that those existing laws leave too much uncertainty when an autonomous agent, rather than a person, carries out the conduct.

The legislation comes amid a broader disagreement in Washington over whether new AI-specific laws are necessary.

Administration officials have argued that existing laws already provide mechanisms for addressing AI harms. National Intelligence Director Jay Clayton said Wednesday that the government already has consumer protection and product-liability laws as well as the Justice Department and other regulatory structures.

President Donald Trump has argued that imposing restrictions on AI could hobble American companies in the global race for the technological dominance against China.

In a Truth Social post last month, Trump dismissed broader concerns about AI, writing that “AI taking over the World, destroying Humanity, and all other things bad, is a HOAX.” He also declared: “The only control or ‘guardrails’ that AI needs is a STRONG AND SMART (High IQ!) PRESIDENT, and the U.S.A. has that, in spades!”

Trump has not, however, argued that AI should operate without any safeguards. Asked by reporters on September 29 whether AI needed regulation or guardrails, he said the industry should largely police itself while existing federal authorities retain their enforcement powers. “There should be tremendous self-regulation, and we automatically have regulation with the Department of Justice, the FBI, all of that,” Trump said. “But the self-regulation is very important.”

Altman has not publicly appeared before either of the hearings, but OpenAI has acknowledged the underlying incidents and described them as serious warnings about the technology.

After the Hugging Face incident, OpenAI said its models had become powerful enough to find and exploit security weaknesses across multiple systems. The company called the episode a “warning shot” and said highly capable agents can work around technical controls, communicate through unapproved channels and take actions that no human directly instructed them to take.

OpenAI said it responded by creating more isolated sandboxes, restricting internet access, tightening access to model weights and investing in additional monitoring.

On the Australian incident, OpenAI apologized and acknowledged that its response should have been better. The company said the Australian breach represented “a new kind of cyber incident” and an emerging global challenge.

Albanese said Altman personally accepted that OpenAI had not done enough. Asked whether Altman had apologized, the Australian prime minister said: “He clearly accepted that the company had not done good enough.”

OpenAI has also said the Australian incident involved an internal model that was not intended for public release and did not have the full safeguards used in its public products.

The company's position on the Hugging Face incident is similarly that it was an internal cybersecurity evaluation that exposed weaknesses in its safeguards—not an intentional attack on an outside company.

Warnings about increasingly autonomous AI systems have begun to come from inside the industry itself. Anthropic CEO Dario Amodei has pointed directly to the Hugging Face incident as evidence of what could happen as AI agents become more capable. In a September essay, Amodei wrote that “in 6–12 months such a swarm could be capable of taking over the entire internet with a persistent botnet,” potentially causing “hundreds of billions of dollars in damage” if AI capabilities advance without adequate safeguards.

Speaking about the incident in a CNN interview, Amodei said he was particularly alarmed by the way the agents cooperated with one another after breaking out of their testing environment. “You have almost this collective swarm, like a hive of insects,” he said, describing a situation in which the agents were collectively working toward a destructive objective. He warned that a more capable version of such a swarm could potentially attack companies across the internet.

Altman has also acknowledged that the incidents warrant a change in how the industry approaches safety. Speaking at a conference in September, he said: “These models have gotten so good so fast that we need to treat the alignment and monitoring and security with a new level of rigor.” He added that companies should be willing to “pace our development of capabilities such that alignment, safety, and monitoring are always ahead of capabilities.”

The warnings come as reports of AI systems circumventing safeguards have multiplied. OpenAI's Hugging Face incident is one of the most prominent examples, but researchers have also documented AI agents attempting to circumvent restrictions and access systems during security evaluations.

The incidents have intensified a debate that now extends beyond whether AI companies can build more capable systems to whether they can reliably control what those systems do once they are given the ability to act autonomously.

Existing laws can prohibit unauthorized access and provide civil remedies for certain harms. But lawmakers and legal experts disagree about whether those laws are sufficient when an AI agent makes decisions that its developer or user did not explicitly anticipate.
