Abstract

The invention provides a smali intermediate language-based static detection system and method. A preprocessing module is used for performing simple and quick preliminary screening analysis on mobile application software, judging whether the current mobile application software has a possible sensitive behavior or not, and judging whether a subsequent static behavior analysis program needs to be carried out or not; a rule library module is a rule which the preprocessing module depends on during sensitive behavior analysis; a sensitive behavior detection module performs detailed behavior detection on the mobile application software judged to have the sensitive behavior by the preprocessing module; and a result generation module is used for generating a report by basic information and sensitive information of the mobile application software and outputting the report. According to the smali-based detection system, the information completely reserved in the Android application software can be subjected to behavior analysis, so that the sensitive behavior existent in the application software is accurately detected out.

Description

technical field [0001] The invention relates to the technical field of analysis of mobile application software, in particular to a static detection system and method based on smali intermediate language. Background technique [0002] In general, the static analysis technology of mobile application software is to decompile to the source code, because the Android code itself cannot completely match the Java syntax and there will be information missing or decompilation failure in the process of decompiling to the source code. Carry out complete information analysis, so a static detection system based on smali intermediate language is designed and implemented. Compared with the static detection system based on source code, it has better detection accuracy and lower false alarm rate, and has a higher detection efficiency. There is a great improvement. [0003] At present, a lot of research has been done on the static detection technology of application software at home and abroa...
