Problems solved by technology
[0003] Most of the relevant detection technologies are limited to the pairwise comparison of application feature information. The time-consuming problem prevents these detection methods from providing detection services for large-scale application markets; In the detection tasks of large-scale application markets, it is still necessary to compare all applications in pairs, and the vector extraction complexity and comparison time-consuming have a large room for improvement; moreover, relevant detection technologies cannot provide specific similarity information of applications, and cannot Provide assistance for subsequent analysis and detection

The present disclosure provides a method for detecting repackaged applications, electronic equipment and storage media, the method comprising: obtaining the source code files of the application to be tested and a plurality of sample applications, and extracting method calling information from them; according to the method calling information from Screening a plurality of similar applications from a plurality of sample applications; determining corresponding call characteristic information according to the method call information; screening and determining similar applications from a plurality of similar applications according to the call characteristic information; obtaining the application to be tested and The signature information of the similar application, in response to the inconsistency between the signature information of the application under test and the signature information of the similar application, determine that the application under test is a repackaged application, and the electronic device includes a memory, a processor and a storage A computer program implementing the repackaged application detection method can be run on the memory and on the processor, and the computer instructions stored in the storage medium are used to cause the computer to execute the repackaged application detection method.
Description
technical field [0001] The present disclosure relates to the technical field of computer security detection, and in particular to a method for detecting repackaged applications, electronic equipment and storage media. Background technique [0002] With the rapid development of mobile terminals and the gradual maturity of network technology, the Android system has grown into the most popular operating system at present, bringing great convenience to people's lives. People can not only make and receive calls through smartphones, but also perform operations such as transaction transfers, online shopping, and watching videos through smartphones. The vast user base has led more and more developers to devote themselves to Android application development. Subsequently, repackaged applications began to appear in the application market. Repackaged Android applications refer to malicious attackers attacking genuine applications through decompilation and cracking technology, retaining...
