A Saudi national employed as an OpenAI engineer since July 2025 has been charged with planting a covert audio recording device in an executive conference room at the company's San Francisco office. The device, a thumb-sized Seeed XIAO ESP32-S3 Sense unit concealed in toilet paper and plugged into a TV USB port, was discovered during a September 30 sweep after being installed around September 28.
Abdulrahman Alfozan, 35, allegedly used a productivity tool to scout meeting rooms, executive calendars, and leadership locations despite lacking authorization for the space. A chatbot linked to his spouse reportedly queried prompts on building continuous audio recorders, improving live listening, and encrypting SD cards. CCTV footage captured him entering the room and inspecting behind the TV on October 5, the same day a second similar device turned up in his unattended bag.
OpenAI terminated Alfozan and stated it has no indication of model weights, source code, or customer data being accessed or exfiltrated. The DOJ complaint frames the target as sensitive discussions on proprietary research, product plans, government engagements, and commercial relationships. FBI Director Kash Patel called protecting American "SI" innovation a top counterintelligence priority.
The case underscores how routine insider access at frontier AI labs now carries national security weight, with OpenAI itself leveraging its models to trace the device back to the perpetrator.
