North Carolina State University develops tool to detect malware on Android devices. Practical Root Exploit Containment (PREC) is trained to uncover aberrant code written in C programming language. The tool looks for root exploits, in which a program gains system admin. access rights to the device. PreREC is unique in that it can identify calls made to native C code from a Java program, and check to see if such actions fit into the application’s profile for typical usage. PreC was able to identify all of the root exploits with a minimum number of false alarms.”]
