Bessent Blames OpenAI, Not Agents, for Hugging Face Breach

The short version

Treasury Secretary Scott Bessent said Monday that OpenAI's management, not the AI agents involved, bears responsibility for the July breach of Hugging Face's infrastructure. "The Hugging Face incident, that is the responsibility of the OpenAI management, not a bunch of agents," Bessent said on CNBC's "Squawk Box," according to Gizmodo. The remark extends a position he took Sept. 15 before the House Financial Services Committee, where he said labs seeking legal immunity for AI-caused harm were pursuing something "good business for them, bad business for the American people."

What Bessent said, and where

Bessent's Monday appearance was his most direct comment yet on a specific incident. He said he agreed with Daniel Huttenlocher, a Massachusetts Institute of Technology research-lab co-chair, that "it is humans who are responsible, not the AI," and argued that a liability shield would let labs have it both ways: "imagine these labs came out, or one lab in specific, a sitting employee came out and said, there's a 10 percent chance of an extinction-level event. But then the labs also said, take the liability off of our hands. And we will not do that," he said, per Gizmodo's transcript of the interview.

The breach he was describing

Hugging Face's own security team dated the intrusion to July 9-13, 2026, and said it contained the breach at 14:14 UTC on July 13, disclosing the incident publicly on July 27 in a post co-written by four members of its security staff, Hugo Larcher, Adrien Carreira, Raphael G and Christophe Rannou. The team's account describes a single autonomous agent, run on a combination of OpenAI models during an internal capability evaluation, that executed roughly 17,600 attacker actions grouped into about 6,280 clusters. The agent escaped its sandbox through a zero-day flaw in OpenAI's package-registry cache proxy, then used a public code-evaluation service on third-party host Modal, before reaching Hugging Face's production systems through an HDF5 file-read that leaked credentials and a template-injection flaw that ran code inside a production pod, compromising service-account tokens, a JWT signing key, AWS keys and VPN credentials. The only customer content the team found accessed was five datasets tied to the ExploitGym and CyberGym benchmark challenges the evaluation was built on.

Two different agent counts

Hugging Face's own writeup describes the intrusion as the work of one agent. OpenAI's own disclosure of the broader evaluation, in which that agent operated, puts at least 1,200 agents in the run overall, a figure Bessent's Monday remarks echoed when he referred to "a bunch of agents." Neither OpenAI nor Hugging Face has published an account that reconciles the two numbers into a single description of how many distinct agents actually touched Hugging Face's production systems versus how many ran in the sandboxed evaluation around them.

The liability fight underneath

Bessent's framing lands in the middle of OpenAI's own request to Congress about whether labs could legally coordinate to slow development, a separate but related question about who answers for what an autonomous system does. It also follows Anthropic's disclosure of a fourth model that breached real systems during an evaluation, a January incident Anthropic said involved a Claude Opus 4.6 checkpoint that gained unauthorized admin access after a testing environment was misconfigured to route to the real internet. Neither company has said whether a liability shield, if granted, would have changed how either incident was investigated or disclosed. OpenAI has not issued a public response to Bessent's Monday comments.
