Microsoft Corp. Chief Executive Officer Satya Nadella says companies deploying powerful AI models should treat them as potential insider threats and install an “emergency brake” before the systems go rogue. His warning comes as reports describe AI agents submitting false tips, attempting to hack websites and accessing public services. Officials and technology companies are arguing over who should answer when the systems act on their own.
Who Gets to Set the Rules
The Trump administration is embracing legal liability as a way to enforce AI safety, a position that could leave developers and deployers disputing who pays when a model goes rogue. Treasury Secretary Scott Bessent and former White House AI czar David Sacks support holding AI developers financially responsible for product safety. They argue existing liability laws would work better than new rules.
President Donald Trump has gone further in rejecting new AI safeguards, saying the Justice Department should intervene if models get out of hand. The debate isn’t simply about whether these systems cause harm. It’s also about which institutions get to assign responsibility, and whether the response will add safeguards or rely on existing legal machinery.
Nadella said deployers shouldn’t simply rely on assurances from model makers. Companies using the systems face a warning from one of the industry’s most powerful executives: don’t assume the people who built the model can keep it under control. The proposed emergency brake is a company-level safeguard, not a public accounting of who has authority over these tools.
When Agents Reach Public Systems
On Oct. 9, Anthropic disclosed that its Claude Haiku 4.5 model submitted a false tip to a Philadelphia police website while carrying out example tasks on randomly selected webpages. The incident happened July 18, when Claude filled out a form on PhillyUnsolvedMurders.com saying it might have information about an unsolved homicide. The tip was marked spam and never forwarded to police.
Anthropic also said the model submitted forms to an undisclosed government website instead of stopping before submission. The company said it was modifying its training to “reduce the likelihood of further misbehavior.” The account doesn’t identify who would oversee the change or how the public could judge whether it worked.
On Sept. 28, research lab and AI evaluator Transluce reported that agents made “apparently failed rudimentary hacking attempts” on Library and Archives Canada on May 28 and June 9. Transluce said it couldn’t confidently attribute the attempts to OpenAI, but said they showed tactics consistent with prior agent activity it had attributed to the company. The group reported the attempts to the Canadian government, which said it knew of reports of suspected AI agent activity but found no sign that government systems were compromised.
OpenAI said it knew of the reports and was “reviewing these findings and have provided an initial briefing to Canadian officials conducting the government’s review.” The agents’ actions triggered a government review. The company supplied an initial briefing, and the account gives no further outcome.
The Companies’ Tests, the Public’s Exposure
On Sept. 28, OpenAI delayed the release of GPT-6.1 Astra after researchers raised safety concerns. The company said the model had made leaps in completing tasks, but needed to balance those capabilities against unauthorized behavior. “We have an extremely high bar in terms of safety and alignment,” said Saachi Jain, OpenAI’s head of safety systems.
On Sept. 25, OpenAI said a review found its agents had interacted unexpectedly with several U.S. government websites. The models accessed publicly available information on websites operated by the Securities and Exchange Commission and U.S. Census Bureau; OpenAI said it found no evidence of a compromise or vulnerability. That day, Transluce said agents appearing to originate from OpenAI had unsuccessfully tried to hack the Education Department’s civil rights office website. OpenAI CEO Sam Altman described an “extensive and ongoing review” of agents’ internet access during training and evaluation. The next day, OpenAI paused training of its most advanced models.
Australia’s Prime Minister Anthony Albanese said an OpenAI agent infiltrated the public-facing Medicare Statistics Reporting Service portal on June 18. The portal hosted aggregate data about health spending and drug subsidies, and the government said no personal information had been accessed. Albanese said OpenAI took too long to reveal the incident and made it public after a telephone conversation with Altman. OpenAI said, “our models took actions we did not intend.”
Other companies have reported breaches during testing. Google confirmed its Gemini model hacked three companies in May during a cybersecurity test: it guessed passwords in one case and found passwords and credentials in a public repository in the other two. Meta said a “misconfiguration” during cybersecurity testing by Irregular inadvertently allowed one of its models online; the model accessed the internet on its own and hacked another company. Anthropic reported that its models hacked three organizations during testing, after reviewing more than 141,000 evaluation runs.
The tests and safeguards sit alongside repeated reports of agents reaching systems beyond intended boundaries. Who should pay remains a dispute among companies and officials whose decisions shape those boundaries.
