An embodiment of the present disclosure provides a component data extraction method of an operating system, as shown in fig. 1, the method may include:
step S110, determining version information corresponding to an operating system on which the terminal device to be tested depends, as target version information.
In this disclosure, the operating system refers to a processing system of the terminal device to be tested, and may be an android processing system or an IOS (apple mobile operating system) processing system, for example, in an embodiment of the present disclosure, the operating system on which the terminal device depends may be the android operating system. The version information is used for representing a currently-used version of the operating system, and multiple versions can exist in the same operating system, for example, when the operating system is an android version, the used version can be an android 5.0 version or an android 9.0 version.
Step S120, obtaining an installation package file of the application program to be tested in the terminal equipment to be tested, and determining the file type of the installation package file according to the target version information.
In practical applications, when the versions of the operating systems are different, the file types of the installation package files of the application programs included in the operating systems are also different. For example, when the operating system of the terminal device is an Android system (Android), if the installed version is any one of Android 1 to Android 4, the format of the installation package existing in the system is a dex type file and an apk type file, if the installed version is any one of Android 5 to Android 7, the format of the installation package existing in the system is an optimized odex type file and an optimized apk type file, in the Android 8 version, the odex type file is changed into a vdex type file, and the version after the Android 9 changes the odex type file into a cdex type file. Based on this, in the embodiment of the present disclosure, after knowing the version information corresponding to the operating system on which the terminal device to be tested depends, the file type of the acquired installation package file of the application program to be tested may be determined according to the corresponding version information.
And step S130, according to the file type, performing decompiling processing on the installation package file to obtain a code text.
In practical application, when the file types of the installation package files are different, the decompiling modes of the installation package files are different, and after the file types of the installation package files are known, the decompiling processing mode corresponding to the type can be selected to decompile the installation package files to obtain the code texts. Wherein the code text may be a smali code.
In step S140, system component data is extracted from the code file.
In practical application, each component of the application program to be extracted usually exists under a System/app, a priv-app and a frame, and correspondingly, when the code text corresponding to the installation package file is obtained, the data in the System/app, the priv-app and the frame is embodied in the code text, so that the System component data corresponding to the application program to be extracted can be obtained from the code file. The embodiment of the present disclosure is not limited to the implementation of extracting system component data from a code file, and an alternative implementation may be to invoke a text editor to extract system component data from a code file.
In the embodiment of the disclosure, when extracting system component data corresponding to an application program to be tested, a file type of an installation package file of the application program to be tested can be determined according to version information corresponding to an operating system on which a terminal device to be tested depends, and then decompiling is performed in a decompiling mode corresponding to the file type, at this time, decompiling can be performed on each version related to the system, and compatibility of each version of the operating system is improved; in addition, in the embodiment of the disclosure, after the code text corresponding to the installation package file is obtained through decompiling, the system component data can be quickly, quickly and efficiently extracted based on the code text, so that quick safety test can be realized, and the low test efficiency is improved.
In an embodiment of the present disclosure, the system component data includes a component type and action data corresponding to the component; the component types include a broadcast component, an active component, and a service component.
In practical application, the system component data corresponding to the application to be tested may include multiple types, such as a broadcast component, an activity component, a service component, and the like, and each component further includes action (action) data, and at this time, when the system component data corresponding to the application to be tested is obtained, the system component data may include each component type and action data corresponding to each component type.
In the embodiment of the present disclosure, the action data corresponding to each component type is the action data corresponding to the class name included in each component type.
In practical application, each component type includes a class name, each class name has corresponding action data, and the action data corresponding to each component type extracted at this time is the action data corresponding to the class name included in each component name.
In an embodiment of the disclosure, extracting system component data from a code file includes:
searching Manifest files in the code text, and extracting component data of activity components, component data of service components and component data of a broadcast register form of a broadcast component from the Mainfest files;
and searching a register field in the code text, and extracting the component data of the broadcast registration form of the broadcast component.
In practical application, when the system component data corresponds to different component types, the implementation modes of obtaining the system component data corresponding to the application program to be tested based on the code text extraction are different. For example, component data of an activity component, component data of a service component, and component data of a broadcast registration form of a broadcast component may be extracted based on a Manifest file in a code text. Further, in practical application, since the component data of the dynamic broadcast registration form of the broadcast component is not embodied in the Manifest file in the code text, the register field in the code text may be scanned, and the component data of the dynamic broadcast registration form of the broadcast component may be extracted.
In the embodiment of the present disclosure, according to the type of the file type, performing decompiling processing on the installation package file to obtain a code text, including:
if the file type is a first type, decompiling the installation package file by adopting a decompiling tool corresponding to the first type, wherein the first type comprises an APK file type and a dex file type;
if the file type is not the first type, converting the installation package file into an installation package file of the first type to obtain a converted installation package file; and decompiling the converted installation package file by adopting a decompiling tool corresponding to the first type.
In practical application, when the file types of the installation package files are different, the decompilation modes of the installation package files are also different, and at this time, the decompilation of the installation package files can be carried out according to the file types. In the embodiment of the present disclosure, various file types may be divided into a first type and a non-first type, and the first type may include an APK (android package) file type and a dex file type.
Further, when the installation package file is decompiled according to the file type, the file type of the installation package file can be determined, if the file type is determined to be the first type, the decompiling tool corresponding to the first type can be directly adopted to decompile the installation package file, if the file type is determined to be not the first type, the installation package file can be converted into the installation package file of the first type (namely converted into the APK file type or the dex file type), and then the decompiling tool corresponding to the first type is adopted to decompile the converted installation package file. When the first type of APK file is of the type, the corresponding decompilation tool is an apktool tool, and when the first type of dex file is of the type, the corresponding decompilation tool is an apktoolbackskmali tool.
When the file type is not the first type, different implementation modes can be adopted according to the file type when the installation package file is converted into the installation package file of the first type. For example, when the file type is the odex file type, the backsmamli tool may directly perform decompiling on the installation package file of the dex file type after converting the installation package file from the odex file type to the dex file type; when the file type is a vdex file type, a vdex extra tool can be adopted to convert the installation package file from the vdex file type to a dex file type, and then a backsmali tool is adopted to perform decompiling on the installation package file of the dex file type obtained after conversion; when the file type is the cdex file type, the installation package file can be converted into the dex file type from the cdex file type by adopting a compact _ dex _ coverters tool, and then the installation package file of the dex file type obtained after conversion is decompiled based on backsmali.
In addition, in practical applications, the installation package file of the application program to be tested in the operating system may be stored in various forms, for example, in a 32-bit form or a 64-bit form. Based on this, in the embodiment of the present disclosure, before the installation package file of the application program to be tested is decompiled, the form adopted by the installation package file during storage may also be determined, and the installation package file is correspondingly processed according to the form adopted during storage, for example, the installation package file stored in the form of 64 is moved to a specified directory (e.g., a frame directory), or the installation package file stored in the form of 32 is deleted in order to reduce the data amount.
In an embodiment of the present disclosure, based on the code text, the method further includes:
performing duplicate removal processing on all the extracted component data;
and storing the de-duplicated component data in a plurality of files in a classified manner, wherein the files are used for performing security test of the unauthorized and denial of service types.
In practical application, repeated component data may exist in component data extracted based on a code text, and if an application program to be tested is directly tested on the basis of the extracted component data, due to the fact that the repeated component data exists, data processing amount may be increased, so that in the embodiment of the present disclosure, each extracted component data may be subjected to deduplication processing, the deduplicated component data is obtained, and the deduplicated component data is classified and stored in a plurality of files based on component types included in the component data, so that subsequent security tests of override and/or denial of service types may be performed.
