Abstract

A method for evaluating the risk of data leakage in an application includes the steps of: extracting a DEX (Dalvik Executable) file and a so (Shared Object) file by decompressing an APK file of a mobile application; extracting DEX code information from the DEX file by parsing the DEX file; translating a content of the so file into IR (Intermediate Representation); extracting IR code information from the translated IR; generating a call-reference structure between the DEX file and the so file by processing the extracted DEX code information and the extracted IR code information; and outputting weakness information according to a risk designated in advance based on the generated call-reference structure. Accordingly, it is possible to extend the call-reference coverage of an android application.
