Inter-component communication (ICC) serves as a key element of any Android app's implementation. Specifically, an Android app uses Intents as the main mechanism for ICC to complete tasks such as switching between different user interfaces, starting background services, communicating to other apps on the Android device, and saving or retrieving data from device storage. Thus, dissecting how an app...
As the Android app market keeps growing, there is a pressing need for automated tool supports to empower Android developers to produce quality apps with higher productivity. Yet existing tools for Android mostly aim at security and privacy protection, primarily targeting end users and security analysts. Towards filling this gap, we present DROIDFAX, a toolkit that targets the developers to help them...
Most existing research for Android focuses on particular security issues, yet there is little broad understanding of Android application run-time characteristics and their implications. To mitigate this gap, we present the first systematic dynamic characterization study of Android apps that targets a broad understanding of application behaviors in Android. Through lightweight method-level profiling,...
Inter-Component Communication (ICC) enables useful interactions between mobile apps. However, misuse of ICC exposes users to serious threats, allowing malicious apps to access privileged user data via another app. Unfortunately, existing ICC analyses are largely insufficient in both accuracy and scalability. Most approaches rely on single-app ICC analysis which results in inaccurate and excessive...
To devise efficient approaches and tools for detecting malicious packages in the Android ecosystem, researchers are increasingly required to have a deep understanding of malware. There is thus a need to provide a framework for dissecting malware and locating malicious program fragments within app code in order to build a comprehensive dataset of malicious samples. Towards addressing this need, we...
