Xplora 4 smartwatch has a backdoor that could be activated by an encrypted SMS. The device is manufactured by Chinese company Qihoo 360, which was one of two dozen companies that, as of May, can no longer receive exports of U.S. technology due to national security reasons. The company says it deployed a patch on Thursday that removes the backdoor. The XPLora 4 is sold in the U.K., Spain, Germany, France and Poland, and is marketed in Europe.”]
