Security researchers have unveiled a backdoor functionality in smartwatches designed for children by Chinese company Qihoo 360 and sold in Europe under the Xplora brand. The watch comes with a GPS module and acts very much like a phone, allowing parents to quickly communicate with their children. Researchers found a Persistent Connection Service that collects a list of possible commands, allowing remote operators to interact with the device. The biggest issue is that the same key used by the parents to authenticate when controlling the watch is likely available to the watch manufacturer.”]
