North Carolina State University researchers have developed a tool to detect mobile malware that attempts to run Root exploits in Android devices. Root exploits take control of system administration functions of the operating system that gives the hacker an unrestricted control of user’s Smartphone. An application has not permission to read your messages or contacts or the GPS location, but after getting root access it will be able to steal any data from your device. PREC targets the code written in C language which is usually used by hackers to create malware.
