3. Related WorkZhou et al. [2] present their study of different traits of Android malwares including the modes of propagation andinstallation used by Android malwares. They observe that the most used mode is app repackaging. Vidas et al. [3]observe the same thing in their study. They observe that the majority of malware families in their dataset employedrepackaging. There are several techniques which detect app repackaging by detecting how similar the source codesof the app is to some existing apps [4] [5]. Wu et al. [6] and Ren et al. [7] propose detection of app repackagingthrough a watermarking-based authentication mechanism. Some existing techniques [8] [9] [10] detect apprepackaging based on similarity in data or control dependencies in the source code of the apps.
