A Bluetooth-enabled car battery monitor, sold under multiple brand names including PowerTech and Repco, has been found to covertly track users’ physical location via their smartphones. The device, which requires an app to work, collects GPS coordinates, cell tower data and nearby Wi-Fi beacons. The information is sent to servers in Hong Kong and mainland China, raises serious privacy concerns due to the lack of a legitimate reason for such data to be collected. At the time of writing, location data is sent to dualstack-cgicol.amap.com/106.11.130.194, hosted by Alibaba Cloud in Beijing, and bm2.quicklynks.com/47.244.125.231, hosted by the same provider in Hong Kong.
