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.

Although Chinese officials portrayed the exploit as an effective law enforcement technique, internet freedom advocates are urging Apple to address the issue quickly and publicly.
