A target application security detection method, device and electronic equipment

Abstract

The invention discloses a target application security detection method, device and electronic equipment, capable of performing accurate anti-aliasing processing and effective security detection on the target application. The method includes: decompiling the target application to generate an intermediate expression; extracting the key characteristic value of the confusing control flow relationship between multiple program blocks that make up the intermediate expression; Restoring the confusing control flow relationship to obtain the normal control flow relationship; optimizing the normal control flow relationship, and generating the corresponding executable program according to the optimized normal control flow relationship; testing the security performance of the executable program, and outputting the security testing result . The device includes a decompilation module, a feature extraction module, a restoration module, an optimization module and a detection module. The electronic device includes a memory, a processor, and a computer program stored on the memory and capable of running on the processor to implement the target application security detection method.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminal software security, in particular to a target application security detection method, device and electronic equipment. Background technique [0002] With the rapid popularization of smart terminal devices, the number of application software applicable to smart terminals has also shown explosive growth. With the rapid growth of mobile applications, the number and types of malicious software have also begun to increase, and the subsequent security risks have also had a serious impact. Research has found that more and more malicious software has begun to use software obfuscation technology to escape the detection of existing security detection methods, most of which use the control flow flattening method as a blueprint to change the program control flow of its own software or Complications greatly increase the difficulty of deciphering. [0003] Some existing feasible anti-obfusc...
