Researchers at the University of Cambridge say 87 percent of Android devices in the market are insecure, placing the blame on manufacturers who do not provide regular security updates. The research is based on data from 20,400 devices with details pulled from an app that’s available through Google Play. The fragmentation in the Android market could help in some cases such as when attackers go after the segment of the user base with vulnerable devices ignoring those where a given attack wouldn’t work. Researchers recommend users only install apps from Google’s Play Store since it performs additional safety checks on apps.”]
