The VDLoader malware family, which also constituted 3 percent of the Android malware threats Trend Micro found, is embedded into mobile apps and was the first malware to contain an auto update feature. Detected mainly in Asia, this is one of a variety of different SMS Trojan families. VDLoader hides in the background of a mobile application. It contacts a remote server and then begins flooding the victim's phone with text messages, urging the user to load additional applications onto the device, Trend Micro said. It also collects data about the apps already installed on the device.
