Indiana University researchers say they’ve come up with an effective way to ferreting out malicious Android apps from online stores. A scanner called MassVet does not rely on signatures or behavior-based detection, the researchers said. Instead, it compares methods in Android programming between known legitimate apps and potentially harmful ones to separate benign from malicious ones. The biggest offenders were four Chinese Android marketplaces: Anzhi (39 percent of apps scanned were malicious); Yidong (36 percent); yy138 (28 percent); and Anfen (23 percent)
