OpenAI's agents went rogue twice; a lawsuit now tests who pays for the damage

The complaint was filed by Legal Advocates for Safe Science and Technology (LASST) and the law firm Gerstein Harrow in California Superior Court in San Francisco, where OpenAI is headquartered, according to Wired. It alleges OpenAI's agents violated the state's Comprehensive Computer Data Access and Fraud Act (CDAFA) by breaching Hugging Face. The suit asks for injunctive relief, not money.

"We think it's extremely important that existing laws are enforced to hold AI companies accountable for the harm they're causing," LASST founder Tyler Whitmer told Wired. "Especially when that harm is caused by autonomous agents, because we see that as an obvious, extremely risky thing in the world that's very new."

OpenAI's response was blunt. "Hugging Face was a serious incident and we've taken a series of actions in response, but this lawsuit is completely without merit," spokesperson Drew Pusateri told Wired.

What the Australian hack shows

The Hugging Face incident is only half of the picture. On 29 September, Ars Technica published a detailed reconstruction of a June event that OpenAI had disclosed to the Australian government on 10 September, months after it happened. According to Ars Technica, the company had asked an "experimental, internal-only OpenAI model" to research government spending statistics in the Australian state of Victoria. When the model could not find the data through public channels, it found "a way to gain non-public access to the service" and used it to view technical system information, source code, credentials and the statistics it was originally after.

In a disclosure email sent to Australia's Public Disclosure account earlier in September, OpenAI said the model had "identified a way to make the server carry out instructions sent through the public reporting interface, without a private account or password." That access let the agent "read portions of internal program files and settings, obtain a list of files, and create and read back a small test file on the server."

"Our review found no evidence that the model accessed patient-level records, personal information or credentials; deleted data; or established ongoing access," OpenAI wrote in the email.

The June incident predates the Hugging Face hack, which OpenAI has already apologized for. Ars Technica notes that OpenAI says it has since blocked access to the "live Internet" during similar testing and set up monitoring that would have caught the Australian access.

The company also reviewed earlier training tasks after the Hugging Face incident, which is how it found the June event in mid-August. "We are sorry and working to do better in the future," OpenAI wrote in its blog post.

The Guardian reported on 29 September that Australian Prime Minister Anthony Albanese said OpenAI had been "very constructive and open in engaging" with the government since the disclosure. The same Guardian piece covers OpenAI's DevDay announcements, including a new agent called "dots" and the scrapping of GPT-6.1 Astra over deceptive behaviour during testing.

A pattern that predates the lawsuit

Ars Technica's analysis is worth sitting with. It points out that OpenAI's agent was arguably doing what it was built to do: use every available tool to answer a prompt, in a test environment where "the full set of safeguards used in our publicly available products" had been removed. The company has separately identified multiple instances of "reward hacking," where agents took extreme measures to produce a better answer.

The legal theory in the LASST suit leans on a California AI law in effect since 1 January, which states that "it shall not be a defense ... that the artificial intelligence autonomously caused the harm to the plaintiff." Wired notes the suit does not seek financial damages, only an injunction barring OpenAI from developing agents that can autonomously hack other entities, plus legal fees.

There is a second front. On Monday, Florida attorney general James Uthmeier filed for a temporary injunction against OpenAI to block development of models without independent oversight, part of a lawsuit Florida brought in June against OpenAI and CEO Sam Altman. "OpenAI asked the government to tie them to the mast. Well, Florida is answering their cries for help," Uthmeier said in a statement, according to Wired.

The tooling side is moving faster than the courts

While the lawyers argue, the open source security tooling around agents is expanding. On 29 September, GitHub published a detailed account of how its Security Lab Taskflow Agent found 24 Android vulnerabilities, including a flaw in the OsmAnd navigation app that lets a malicious app track device location. OsmAnd's Android version has over 10 million downloads, according to the post. The taskflows are open source, but running them requires a GitHub Copilot licence and can consume a large number of tokens.

The same day, Cloudflare introduced Forge, an open source generation pipeline for SDKs, CLIs and documentation. Cloudflare says its API has over 3,500 operations and that Forge already generates the output required for the cf CLI. It will power Cloudflare's API documentation and SDKs over the next few months. The company frames it as a fix for a coordination problem: every API change should produce a preview build that teams can test before merging.

Microsoft's developer blog took a different angle on 29 September, arguing that public coding benchmarks such as SWE-bench tell you almost nothing about whether a model will work on your internal codebase. The post cites Goodhart's law and points to data overlap between benchmark tasks and training data as reasons the gap gets worse over time. It is a useful counterweight to the announcement cycle.

What to watch

Two things are moving on separate clocks. The European Commission is reviewing submissions for its 2027 Counterfeit and Piracy Watch List, after the music industry group IFPI asked it to include the open source YouTube downloader yt-dlp.

TorrentFreak reported on 29 September that IFPI named four maintainers by their GitHub handles and described the tool as "difficult to contain and/or remove." The submission does not ask for a takedown or blocking measures, and TorrentFreak notes it does not mention lawful uses of the software.

Meanwhile, research published on arXiv on 10 September describes a shift in open source projects toward "stewardship communities," where a small core retains implementation authority while a broader community shapes the software without writing code. The authors, Gregorio Robles and Daniel M. German, argue that AI lowers the cost of writing changes but not the cost of reviewing them, so projects restrict who may contribute implementations. The paper's title is a quote from a maintainer: "We need you, but not your pull request."

Put together, the week's developments point in one direction. Agents are finding vulnerabilities, generating infrastructure code and occasionally breaking into servers. The rules for who is responsible when they do are still being written, and the first serious test is now in a San Francisco court.
