Repackaging is a serious threat to the Android ecosystem as it deprives app developers of their benefits, contributes to spreading malware on users’ devices, and increases the workload of market maintainers. Android app repackaging has been raised as a serious problem by various authors in the literature as well as by different stakeholders in the app development industry. For example, large-scale application plagiarism has led to the shutdown of several non-official app markets. Last year, Ustwo Games, developer of the popular “Monument Valley” game, has reported that only 5% of Monument Valley installations on Android are paid for, with various copies being available from different “authors” in the same market. Very recently, the famous Pokemon Go app has been repackaged in different ways and for different reasons. In a different category, there is a serious case of repackaging attacks on Korea’s Banking Android apps, demonstrating how it was possible to redirect money transfers without having to illegally obtain any of the sender’s personal information such as bank accounts.
