Abstract

The design of Android is based on a set of unprotected shared resources, including those inherited from Linux (e.g., Linux public directories). However, the dramatic development in Android applications (app for short) makes available a large amount of public background information (e.g., social networks, public online services), which can potentially turn such originally harmless resource sharing into serious privacy breaches. In this paper, we report our work on this important yet understudied problem. We discovered three unexpected channels of information leaks on Android: per-app data-usage statistics, ARP information, and speaker status (on or off). By monitoring these channels, an app without any permission may acquire sensitive information such as smartphone user's identity, the disease condition she is interested in, her geo-locations and her driving route, from top-of-the-line Android apps. Furthermore, we show that using existing and new techniques, this zero-permission app can both determine when its target (a particular application) is running and send out collected data stealthily to a remote adversary. These findings call into question the soundness of the design assumptions on shared resources, and demand effective solutions. To this end, we present a mitigation mechanism for achieving a delicate balance between utility and privacy of such resources.
