Washington CNN —Security researchers warned Apple as early as 2019 about vulnerabilities in its AirDrop wireless sharing function that Chinese authorities claim they recently used to track down users of the feature, the researchers told CNN, in a case that experts say has sweeping implications for global privacy. AirDrop lets Apple users who are near each other share files using a proprietary mix of Bluetooth and other wireless connectivity without having to connect to the internet. A Chinese tech firm, Beijing-based Wangshendongjian Technology, was able to compromise AirDrop to identify users on the Beijing subway accused of sharing “inappropriate information,” judicial authorities in Beijing said this week. The Chinese tech firm, Wangshendongjian Technology, that claimed to have exploited AirDrop appeared to have used some of the same techniques first identified by the Darmstadt researchers in 2019, said Alexander Heinrich, one of the German researchers. “Now that Chinese security agencies are exploiting this vulnerability, it’s a tough political problem for Apple.”
