A recorder in the executive room

The Justice Department said on October 13 that an OpenAI employee had been arrested and charged with using, or endeavoring to use, a device to intercept oral communications.

The department’s account is a complaint, not a verdict. The engineer was arrested on October 9 and made an initial appearance in federal court on October 13. The complaint says the person had worked as an engineer at OpenAI since July 2025. If convicted, the maximum penalty is five years in prison, a $250,000 fine, and three years of supervised release. The FBI is investigating. The case is being prosecuted in the Northern District of California.

MODEL is not naming the engineer. A charge is not a finding.

According to the complaint, as the department summarized it: on or about September 30, OpenAI personnel found a surreptitious audio recorder plugged into a USB port on the back of a television in an executive conference room in one of the company’s San Francisco buildings. The device had been concealed in toilet paper. OpenAI determined it was installed on or about September 28, and that its contents were encrypted.

The complaint says the engineer had no authority to access that room or take part in the meetings held there. Those meetings, the department says, often covered highly confidential technical, commercial, and strategic information, including research, product plans, business development, government engagements, and commercial relationships.

The complaint further alleges that, before September 28, the engineer used a productivity tool to look up building addresses, meeting rooms, calendars, leadership locations, and external partner meetings. It alleges that a chatbot account associated with the engineer’s spouse, sharing identifiers with the engineer’s own account, submitted prompts between September 24 and September 30 about building a continuous audio recorder, Wi-Fi connectivity, live listening, and encrypting an SD card. Prompts tied to the device’s header and MAC address, the complaint says, were submitted between September 27 and September 28.

On October 5, the complaint alleges, closed-circuit footage showed the engineer entering the conference room and appearing to look behind the television. The same day, the complaint says, the engineer left a bag unattended in a different room. Security opened it and found a second, similar recorder, along with a wallet and identification.

The department’s release does not say that model weights, source code, or customer data were taken. It describes an alleged attempt to record conversations.
