Chinese spy balloon used US tech to spy on Americans

The Chinese spy balloon that passed over the US early this year used American technology that helped it collect audio-visual information, the Wall Street Journal reported on Wednesday, citing preliminary findings from a closely held investigation.
Analysis from several US defense and intelligence agencies, found that the balloon carried commercially available US gear, along with more specialized Chinese sensors and other equipment to collect photographs, video and other information to transmit to China, the WSJ said, citing US officials.
