On or about September 28, 2026, OpenAI staff discovered a thumb-sized encrypted audio recorder hidden inside toilet paper and connected to a USB port behind a television in an executive conference room at one of the company’s San Francisco offices. The device, identified as a Seeed XIAO ESP32-S3 Sense board with microphone and microSD storage, was found during a security sweep on September 30. OpenAI traced the hardware to Abdulrahman Alfozan, a 35-year-old engineer on its product team, and referred the matter to the FBI.
Details of the arrest and charges
FBI agents arrested Alfozan on October 9, 2026. Prosecutors charged him with one count of using a device to intercept oral communications. He appeared in U.S. District Court for the Northern District of California on October 13 and remains in custody. A detention hearing is scheduled for October 19 before Magistrate Judge Alex G. Tse. If convicted, Alfozan faces up to five years in prison and a $250,000 fine.
Court documents state that Alfozan lacked authorization for the room where the device was placed. CCTV footage reportedly shows him near the room on earlier dates and entering it on October 5 to check behind the television. On the same day, a second identical device was found in a bag he left unattended. Prosecutors allege he used an internal tool to query building layouts, meeting rooms, and executive calendars. A chatbot account linked to his spouse allegedly received prompts about building and concealing recording devices between September 24 and 30.
Background and ongoing investigation
Alfozan, a Saudi national and U.S. lawful permanent resident since 2020, joined OpenAI in July 2025. OpenAI stated it found no evidence that model weights, source code, or customer data were accessed or removed. His lawyer described the allegations as out of character and stressed the presumption of innocence. The charge concerns interception of communications rather than theft of trade secrets or foreign-agent activity.
The case has drawn attention to security practices at leading AI labs amid international competition for advanced models. Officials have described the investigation as a national security matter. The FBI continues to examine the devices and related digital records. Further court proceedings are expected after the October 19 detention hearing.
