FBI agents arrested an OpenAI employee, a Saudi national who had worked at the company for 15 months, on suspicion of planting a hidden microphone behind a television in an executive conference room. Security footage reportedly showed him checking the recording device, and prosecutors noted he had booked a one-way flight to Saudi Arabia. He has been fired by OpenAI and has not been charged with espionage; the company says it has found no evidence he stole sensitive information. The arrest comes amid heightened concern across Silicon Valley AI labs about espionage tactics, including physical surveillance, aimed at stealing proprietary AI technology and model weights.
