Automatic system for measuring security risk of Android application from third party app store

Abstract

Third party app stores are being used by people to pick up cracked or free Android apps. Hackers make use of these stores to distribute malicious apps. So, the level of security risk of downloading and using apps from such stores will be helpful for people who want to use the store. We implement an automatic system that downloads and analyzes every app. Our preliminary result shows that around half of apps from two app stores interesting to us are already known malware.
