Kharon dataset: Android malware under a microscope
Abstract
This study is related to the understanding of Android malware that now populate smartphone's markets. Our main objective is to help other malware researchers to better understand how malware works. Additionally, we aim at supporting the reproducibility of experiments analyzing malware samples: such a collection should improve the comparison of new detection or analysis methods. In order to achieve these goals, we describe here an Android malware collection called Kharon. This collection gives as much as possible a representation of the diversity of malware types. With such a dataset, we manually dissected each malware by reversing their code. We run them in a controlled and monitored real smartphone in order to extract their precise behavior. We also summarized their behavior using a graph representations of the information flows induced by an execution. With such a process, we obtained a precise knowledge of their malicious code and actions. As a result, researchers can figure out the engineering efforts of malware developers and understand their programming patterns. Another important result of this study is that most of malware now include triggering techniques that delay and hide their malicious activities. We also think that this collection can initiate a reference test set for future research works.
