According to the present invention, in execution file reconstruction corresponding to obfuscation for an execution file in the Android platform, when obfuscation for an execution file such as a DEX file is performed, information on a parent-child relationship for each class defined by a class definition item in the execution file is analyzed by recursively establishing the parent-child relationship between classes with reference to class related information on a header of the obfuscated execution file, so as to reconstruct the original class hierarchy structure. |
