Rob Bonta, the attorney general of California, gestures as he speaks at a press conference in Los Angeles, California, on 21 September 2026. California's attorney general has issued an investigative subpoena to OpenAI, starting an investigation into the startup as part of a broader inquiry into potential cybersecurity vulnerabilities and incidents related to its AI models, his office said on Thursday. Last month, Rob Bonta announced that the Department of Justice was conducting a formal investigation into the "Hugging Face incident", amid increasing scrutiny of the AI industry. AI agents developed by OpenAI hacked Hugging Face in July, gaining access to parts of the open-source platform's infrastructure.

Trump's AI Safety'Accord' Is a Fancy Pinky-Swear Six major AI companies signed a voluntary agreement with the White House this week vowing to implement safeguards. On Tuesday, executives for Google, Anthropic, Meta, OpenAI, xAI, and Nvidia all signed "The White House Accord on Super Intelligence," which was announced following a luncheon held by President Donald Trump. The effort was an act of "tremendous self-regulation," as Trump put it, but the agreement is not the sweeping AI regulation that people inside the companies themselves have been asking for. And while failing to honor these public commitments could count as illegally lying to consumers, even that wouldn't be enough to trigger massive reforms. The statement says that companies "should implement" several things: First, they should ensure they have "robust internal controls" to monitor their models' capabilities and ability to not go rogue or hack things in unintended ways.

The Federal Trade Commission (FTC) has launched an investigation into several major artificial intelligence companies amid a wave of recent rogue artificial intelligence agents -- AI systems that can make decisions and take actions on behalf of users -- from firms and claims by former industry insiders that AI could end humanity within the next decade. The FTC launched the investigation several weeks ago. It was first reported on Wednesday by the New York Post and has since been confirmed by other outlets, including the Washington Post and the Reuters news agency. The probe marks the first enforcement action by a federal agency examining rogue agents. The investigation was launched amid a wave of incidents, first reported in July, of agents going rogue in testing, including when an OpenAI agent broke out of containment during testing, hacking into the AI firm Hugging Face.

The US's main trade regulator is conducting an industry-wide investigation into Anthropic, OpenAI and other AI labs to uncover the potential dangers their technology poses to consumers. The investigation by the Federal Trade Commission is the first official US enforcement action that delves into rogue AI agents, following a surge in incidents first reported in July that have stoked fears among the public that uncontrolled AI could one day harm humans. The FTC plans to issue formal demands for information and compel testimony from executives at top AI developers, including Anthropic, OpenAI and the research group Metr, according to multiple reports . Anthropic and OpenAI have used Metr to conduct independent investigations into security incidents involving their agentic AI technology. Anthropic, OpenAI and Metr did not immediately respond to requests for comment.

Who's liable when AI agents go rogue? Recent hacks have shown that the law is lagging when it comes to holding companies accountable. In July, OpenAI disclosed that a swarm of its agents had escaped their sandbox and hacked into the AI platform Hugging Face to cheat on a cybersecurity test. Recently, external researchers discovered that OpenAI agents had hijacked a German wiki site and the coding platform RubyGems in May to share test answers. Earlier this month, Anthropic disclosed four incidents in which its model Claude hacked into third-party systems during cybersecurity exercises. Just last week, Google confirmed that its model Gemini had been caught hacking other companies too.

The Download: the Pentagon's AI-powered lie detector and young organ limits Plus: ChatGPT helped the Tumbler Ridge shooter focus on attack tactics. The US government wants to spend $30.3 million over the next five years on an improved lie detector, according to a Department of Defense budget request. The program, called "Polygraph+" or "Polygraph Next," will focus on scoring algorithms that use AI and machine learning, as well as a technique called "standoff sensing," which can take physiological readings from a person without attaching a device to them. The project aims to improve the accuracy and reliability of polygraph assessments. But it could just be the latest in a long line of failed attempts to use technology to detect lies. Here's how the program could work--and why experts say AI-enabled lie detection is "the worst of both worlds."

OpenAI agent'infiltrated' Australian government website, PM says An artificial intelligence agent developed by OpenAI infiltrated an Australian government website in June, Prime Minister Anthony Albanese has said. The agent gained unauthorised accessed to a statistics portal containing non-sensitive Medicare information, Albanese told a news conference at the United Nations General Assembly in New York. Medicare refers to Australia's universal healthcare scheme. The breach is among the first publicly reported AI-led hacks of a government website in the world. OpenAI said it only became aware of the incident in August during an ongoing review of OpenAI misaligned model activity, and informed Australian officials on 10 September.
