Abstract (in Japanese) (See Japanese page) 
(in English) Android is widely used as a smartphone OS. On the other hand, malware targeting the Android devices is increasing. Sometimes, attackers insert malicious code to benign application to create malware. It is called repackage malware.Attackers may automate the process of repackaging when they create a large amount of repackage malware. However, difficulty and cost of automated repackage have not been well-investigated. In this paper, we evaluate resistance of Android apps to automated repackaging. For reproduction of automated repackage, we insert a test code to benign apps by methods which have been used in actual repackage malware. After repackaging, we check whether the inserted code properly works or not by dynamic analysis. As a result of the experiment, we successfully insert the test code into 75% of all tested popular apps without influencing the functionalities of the original apps. As there is no technical difficulty to replace the test code to malicious code, we conclude that many Android apps are lack of resistance to automated repackage and must consider measures such as Tamper resistant software technology.
