Embodiments of the present disclosure provide 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 equipment to be tested depends as target version information.
The operating system refers to a processing system of the terminal device to be tested, for example, may be an android processing system, or may be an IOS (apple mobile operating system) processing system, and in the embodiment of the present disclosure, the operating system on which the terminal device depends may be an android operating system. The version information is used for characterizing the current version adopted by the operating system, and multiple versions can exist in the same operating system, for example, when the operating system is an android version, the version adopted by the operating system 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 included application programs are also different. For example, when the operating system of the terminal device is Android, if the installed version is any one of Android 1 to Android 4, the installation package exists in the system in the form of dex and apk type files, if the installed version is any one of Android 5 to Android 7, the installation package exists in the system in the form of optimized odex and apk type files, in the Android 8 version, the odex type file is changed into a vdex type file, and the version after the Android 9 is changed 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 obtained installation package file of the application program to be tested may be determined according to the corresponding version information.
And step S130, decompiling the installation package file according to the file type to obtain a code text.
In practical application, when the file types of the installation package files are different, the decompilation modes of the installation package files are different, and when the file types of the installation package files are known, the decompilation processing modes corresponding to the types can be selected to decompil the installation package files to obtain code texts. Wherein the code text may be a smali code.
Step S140, extracting system component data from the code file.
In practical application, each component of the application program to be extracted usually exists under the conditions of System/app and priv-app, framework, and correspondingly, when a code text corresponding to the installation package file is obtained, the code text reflects data in the System/app and priv-app, framework, so that System component data corresponding to the application program to be detected can be obtained from the code file. Wherein, in an implementation manner of extracting system component data from a code file, the embodiment of the disclosure is not limited, and an alternative implementation manner may be to call a text editor to extract system component data from the code file.
In the embodiment of the disclosure, when extracting system component data corresponding to an application program to be tested, the 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 the terminal equipment to be tested depends, and decompilation is performed in a decompilation mode corresponding to the file type, so that decompilation can be realized for all versions involved in the system, and compatibility of all versions of the operating system is improved; in the embodiment of the disclosure, after decompiling to obtain the code text corresponding to the installation package file, the system component data can be quickly, rapidly and efficiently extracted based on the code text, so that the quick safety test can be realized, and the test efficiency is improved.
In the embodiment of the disclosure, the system component data comprises a component type and action data corresponding to the component; the component types include a broadcast component, an activity component, and a service component.
In practical applications, the system component data corresponding to the application program to be tested may include various types of components, such as a broadcast component, an activity component, a service component, and the like, where each component further includes action (action) data, and when the system component data corresponding to the application program 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 action data corresponding to a class name included in each component type.
In practical application, each component type includes a class name, and each class name has corresponding action data, and at this time, the extracted action data corresponding to each component type is the action data corresponding to the class name included in each component name.
In an embodiment of the present disclosure, extracting system component data from a code file includes:
searching a Manifest file in a code text, and extracting component data of an activity component, component data of a service component and component data in a non-dynamic broadcast registration form of a broadcast component from the Mainfest file;
Searching a register receiver field in the code text, and extracting to obtain component data in a dynamic broadcast registration form of a broadcast component.
In practical application, the implementation manner of obtaining the system component data corresponding to the application program to be tested based on the code text extraction is different when corresponding to different component types. For example, component data of the activity component, component data of the service component, and component data in a non-dynamic broadcast registration form of the broadcast component may be extracted based on a Manifest file in the code text. Further, in practical application, because the component data in the dynamic broadcast registration form of the broadcast component is not reflected in the Manifest file in the code text, the register receiver field in the code text can be scanned at this time, and the component data in the dynamic broadcast registration form of the broadcast component is extracted.
In the embodiment of the present disclosure, decompiling an installation package file according to a type of the file type to obtain a code text, including:
if the file type is the 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 the installation package file of the first type to obtain a converted installation package file; 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 decompiling mode of the installation package files is also different, and at this time, the decompiling of the installation package files can be performed 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 decompiling is performed on the installation package file 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 decompil the installation package file, if the file type is determined to be the non-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 decompiled is performed on the converted installation package file by adopting the decompiling tool corresponding to the first type. When the type of the first type of APK file is the type, the decompilation tool corresponding to the type of the first type of the dex file is an apktoolbacksmali tool.
When the file type is not the first type, different implementation manners may be adopted according to the file type in the implementation manner when the installation package file is converted into the installation package file of the first type. For example, when the file type is an odex file type, the backstsmali tool may directly decompil an 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 extraction tool can be adopted to convert the installation package file from the vdex file type to the dex file type, and then a backstsmali tool is adopted to decompil the installation package file of the dex file type obtained after conversion; when the file type is a cdex file type, a compact_dex_controllers tool can be used for converting the installation package file from the cdex file type to a dex file type, and then decompiling is performed on the installation package file of the dex file type obtained after conversion based on the backstsmali.
In addition, in practical application, the installation package file of the application program to be tested in the operating system can be stored in various forms, such as a 32-bit form or a 64-bit form. Based on this, in the embodiment of the present disclosure, before decompiling an installation package file of an application to be tested, a form adopted by the installation package file in storage may be determined, and corresponding processing is performed on the installation package file according to the form adopted in storage, for example, the installation package file stored in 64 forms is moved to a specified directory (such as a framework directory), or in order to reduce the data volume, the installation package file stored in 32 forms is deleted.
In an embodiment of the present disclosure, based on the code text, the method further comprises:
performing deduplication processing on all the extracted component data;
the component data after the duplication removal is classified and stored in a plurality of files, and the files are used for carrying out security tests of override and refusal service types.
In practical application, there may be repeated component data in the component data extracted based on the code text, if the security test is performed on the application to be tested directly based on the extracted component data, the data processing amount may be increased due to the repeated component data, so in the embodiment of the present disclosure, the extracted component data may be subjected to the deduplication process, so as to obtain the component data after the deduplication, and the component data may be classified and stored in a plurality of files based on the component types included in the component data, so that the security test of override and/or denial of service types may be performed subsequently.
Further, in order to better understand the solution provided by the embodiments of the present disclosure, the method provided by the embodiments of the present disclosure is further described below with reference to specific embodiments. Wherein in this example, the operating System of the terminal device is an android System, component data of an installation package file of an installed application program is stored under a System/app, a priv-app, a System/frame (as shown in fig. 2), and correspondingly, in a configuration environment of the terminal device, as shown in fig. 3, the configuration environment of the terminal device includes backsmali, apktool, vdexExtractor, compact _dex_controllers and Java8, where when the types of the installation package files in the operating System are all of a first type, the configuration environment of the terminal device may only include backsmali, apktool and Java8.
In this example, as shown in fig. 4, when component data is extracted, version information corresponding to an operating system on which a terminal device to be tested depends may be first used as target version information, and then, according to the target version information, an installation package file of an application program to be tested is decompiled to obtain a code text corresponding to the installation package file, which specifically includes the following steps:

step S413, converting the vdex file type into a dex file type by adopting a vdex extraction tool;
in step S414, decompiling the installation package file of the converted dex file type by using a backstsmali decompiling tool to obtain a code text.
Further, as shown in fig. 5, after obtaining the code text corresponding to the installation package file, the system component data may be extracted from the code file, which may specifically include:
