Description

Abstract

Mobile devices are becoming increasingly popular. One reason for their popularity is the availability of a wide range of third-party applications, which enrich the environment and increase usability. There are however various concerns centered around these applications: privacy leakage, malware, etc. In this talk, I will present our recent research to secure these apps towards a more trustworthy Android ecosystem. One representative work is Uranine, a system that instruments Android applications to detect privacy leakages in real-time. Uranine does not require any platform modification nor does it need the application source code. It includes a static analysis component to instrument only paths along which privacy leakage may happen. We designed several mechanisms to overcome challenges introduced by framework code, callback functions, etc. Our evaluation of Uranine shows that it is accurate at detecting privacy leakages while providing acceptable performance, with often unnoticeable overhead.
