Abstract

Mobile malware threats have recently become a real concern. In this paper, we evaluate the state-of-the-art commercial mobile antimalware products for Android and test how resistant they are against various common obfuscation techniques (even with known malware). Such an evaluation is important for not only measuring the available defense against mobile malware threats but also proposing effective, next-generation solutions. We developed DroidChameleon, a systematic framework with various transformation techniques, and used it for our study. Our results on ten popular commercial anti-malware applications for Android are worrisome: none of these tools is resistant against common malware transformation techniques. Moreover, the transformations are simple in most cases and anti-malware tools make little effort to provide transformation-resilient detection. Finally, in the light of our results, we propose possible remedies for improving the current state of malware detection on mobile devices.
