Recent researches suggest that among the top 10 viruses infecting the smart phones in India, five are root Trojans. Once these Trojans manage to get into victims’ mobile phones, they are preprogrammed with ability to root the infected devices and embed the major behavior module into the systems. Once the target is rooted and embedded, the device will be totally under the virus control making the device completely compromised. Antivirus tools must have root privilege to kill these Trojans, so they typically live much longer than ordinary Trojans. Root Trojans are also able to silently install other apps on users’ phones and even transmit user data without the users’ knowledge.
