Android-Based Binary Code Function Fast Positioning Technology

To solve the problem that the existing Android reverse analysis method is inefficient and the applicable scenario is single. A fast positioning technology for binary code function based on Android is proposed in this paper, which includes preprocessing, behavior analysis combining dynamic and static, and binary code function comparison, which can accurately and quickly locate the location of binary code function. Based on this research, to further broaden the application scenarios of the fast positioning technology proposed in this paper and realize the automatic analysis of large-scale applications, an automated analysis tool AndPosit is designed. The proposed technology has been experimentally verified that it can be widely used in various Android applications, can accurately locate the target function code, and the efficiency is more than dozens of times higher than the original manual analysis method.
