Abstract—Android, Google open source operating system for mobile devices, has been rapidly grown. Android applications (apps) are uploaded to not only official market, play store, but also other alternative markets. These markets have no inspection system for detecting malicious apps. So, malicious apps can be easily uploaded on the market. Many studies have presented to detect malicious apps for the secure Android mobile environment. But without user participation, it is difficult to detect all of malicious apps. We present a Warning System for detecting malicious applications on Android system. The warning system monitors API calls related suspicious behaviors running on the service layer. After analysis malicious apps, we find that almost malicious apps use similar API calls. We proposed modified Android platform to warn suspicious API calls are running on the service layer. The warning system lets user realize the information of suspicious API calls and block the API calls.

Index Terms—Android security, malware detection, intrusion detection, API monitoring.
