The U.S. Federal Bureau of Investigation (FBI) has accused Abdulrahman Alfozan, a Saudi national, of installing a hidden listening device in a conference room at OpenAI's California office. The FBI stated that Alfozan had been employed as an engineer at OpenAI since July 2025. OpenAI discovered the device on September 30 in an executive conference room in a San Francisco building, subsequently installing cameras that captured Alfozan checking the installation location last week. U.S. Attorney Todd Blanche said the act posed a serious threat to national security and highlighted growing security concerns surrounding sensitive AI research. OpenAI stated that there is currently no indication that the employee improperly accessed or stole model weights, source code, or customer data, and the employee has been terminated. Alfozan made his initial court appearance on Tuesday, facing up to five years in prison and a $250,000 fine.
