Chinese state media on Friday branded Apple's iPhone a threat to national security because of the smartphone's ability to track and time-stamp user locations.
A report by broadcaster CCTV criticized the iPhone's "Frequent Locations" function for allowing users to be tracked and information about them revealed.
"This is extremely sensitive data," said a researcher interviewed by the broadcaster. If the data were accessed, it could reveal an entire country's economic situation and "even state secrets," the researcher said.
Apple was not available for immediate comment.
