Google Acknowledges Having Android Backdoor Triada. Triada has developed a method to create malware on Android phones ready to use even before the clients open or install an application box. The method used by Triada is complicated and unusual for this type of application, Google said. Google didnt mention the names of the devices infected by the malware, which were not sold in the U.S. According to an analysis of anti-malware software vendors, Dr. Web found the backdoors on Chinese manufacturers Leagoo and Nomu.”]
