OpenAI Traces Hidden Office Bug to Fired Worker, Says No Source Code or Data Taken

Federal prosecutors have charged an OpenAI engineer with secretly installing an audio recording device in an executive conference room at the company’s San Francisco offices, the Justice Department said Tuesday.

OpenAI said it identified the engineer and traced the device using its own artificial intelligence (AI) models. The company said it found no indication that the employee accessed or removed model weights, source code, or customer data, and that it fired the employee before alerting the FBI.

The Device and the Digital Trail

OpenAI personnel discovered the device on September 30, plugged into a USB port on the back of a television in a conference room used for confidential meetings, according to the Justice Department. The device had been concealed in toilet paper and installed about two days earlier, and its stored data was encrypted.

The thumb-sized unit carried a microphone and could connect to a camera, according to the FBI complaint. OpenAI told TechCrunch the device had advanced encryption, audio monitoring, and a data-transfer feature built to evade detection.

Before installing the device, Alfozan used a workplace AI tool to query OpenAI about building addresses, meeting rooms, room capacities, calendars, and the locations of leadership and external partner meetings, the complaint alleged. A chatbot account tied to his spouse submitted prompts between September 24 and 30 about building, customizing, and installing a continuous audio recorder and encrypting its storage card, including entries matching the planted device’s unique hardware identifier, according to the complaint.

On October 5, Alfozan entered the conference room and appeared to examine the back of the television, where TechCrunch reported OpenAI had positioned a camera. The same day, OpenAI security opened a bag he left unattended in another room and found a second, similar recording device alongside his wallet and identification, the Justice Department said.

AI Firms as Counterintelligence Targets

The case is being prosecuted in the Northern District of California by the Justice Department’s National Security Division, which is handling it as a counterintelligence matter. Alfozan was charged with using or attempting to use a device to intercept oral communications, an offense that carries up to five years in prison, a $250,000 fine, and three years of supervised release.

What Officials Are Saying: FBI Director Kash Patel said the agency views protecting U.S. AI research from theft as one of its highest counterintelligence priorities and that the investigation is ongoing.

The arrest fits a pattern of U.S. authorities treating AI developers as national-security-sensitive. The Justice Department charged a former Google engineer in 2024 with stealing AI trade secrets for firms in China. OpenAI has tightened physical and insider defenses over the past year, adding fingerprint scanners and restricting which staff can enter areas where sensitive work is discussed, the Financial Times reported.

Alfozan’s attorney, William Pernik, told CBS News his client is presumed innocent and cautioned against drawing early conclusions or treating the prosecution as a matter of nationality. Alfozan has been a U.S. legal permanent resident since 2020. A LinkedIn profile listed prior work at Meta and Microsoft, which Reuters said it could not verify.

What’s Next: Alfozan is scheduled to appear in federal court on October 19 for a detention hearing, where a judge will decide whether he stays in custody while the investigation continues.
