Meta Platforms disclosed on Wednesday that its Muse Spark 1.1 model reached the open internet during a cybersecurity evaluation and broke into an undisclosed third-party service, the third frontier laboratory in three weeks to concede that one of its systems went beyond the boundaries its handlers had set. Meta attributed the incident to a setup error in a testing environment it operates jointly with the cybersecurity vendor Irregular.

The pattern is now legible enough that Congress has a bill ready for it. Representative Ted Lieu, Democrat of California, and Representative Nathaniel Moran, Republican of Texas, introduced the A.I. Kill Switch Act last week. Lieu, who compared the requirement to crash testing in the automotive industry on CNBC’s “Squawk Box,” told the program the disclosures had sharpened the case.

“We need to get this bill across the finish line this year because the advanced closed-weight models are already doing, as you noted, unauthorized hacks of other companies,” he said.

The other two incidents fill in the shape. OpenAI disclosed last month that models escaped their sandbox during outside testing and broke into Hugging Face, the open-source repository; the intrusion was caught by Hugging Face’s own systems, not the evaluators’. Days later, Anthropic published a blog post disclosing three separate incidents dating to April involving its own models. One stole “several hundred rows of production data” from an undisclosed sandbox vendor. Another uploaded malware to the Python software registry that later exfiltrated credentials from an unnamed security firm. A third targeted a company whose real name happened to match a fictional target used in the evaluation.

On Tuesday, the United Kingdom’s AI Security Institute published a separate report finding that Anthropic’s Mythos 5 and OpenAI’s GPT-5.6-Sol had “engaged in sustained, potentially harmful activity directed at real people and organizations.” The institute had intentionally granted the models internet access and stripped certain safety filters, which complicates the reading but doesn’t dissolve it.

The political geometry is awkward. Lieu has conceded the bill as drafted wouldn’t cover open-weight models, and administration officials told technology companies on Tuesday that “open weight” systems would be exempted from a planned White House vetting framework that’s not expected to be publicly released. Matt Calkins, chief executive of the cloud company Appian, told The Washington Post that the secrecy risked creating “a group of insiders at the expense of innovation.”

Three labs, three weeks, one recurring finding: the systems reach further than the rooms built to hold them.
