The Android smartphone operating system includes a Java virtual machine that enables rapid development and deployment of a wide variety of applications. The open nature of the platform means that reverse engineering of applications is relatively easy, and many developers are concerned as applications similar to their own show up in the Android marketplace and want to know if these applications ...

In this report I discuss my Master’s capstone project, ChronoChat-android, an implementation of the ChronoChat instant message application for Android mobile devices [7]. ChronoChat-android allows communication in a chatroom cooperatively hosted by ChronoChat clients. As in other ChronoChat implementations, chatroom participants may be connected via an NDN hub; ChronoChat-android also supports ...

URANOS is an Android application which uses syntactical static analysis to determine in which component of an Android application a permission is required. This work describes how the detection and analysis of widely distributed and security critical adware plugins is achieved. We show, how users can trigger bytecode rewriting to (de)activate selected or redundant permissions in Android applica...

The majority of malware seen on Android has a top-down approach often targeting application programming interfaces (API) of the financially rewarding telephony and short message service (SMS). In this paper we present a proof of concept of compromising an Android based smartphone by targeting the underlying Linux kernel. We adopt an unorthodox bottom-up approach on modifying the operating syste...
