Abstract

The present invention provides a detection method and apparatus for a re-packaged Android application, and relates to the technical field of Android systems. The method comprises: obtaining an Android application to be detected, decompiled codes of a genuine application, and a picture file and an audio file, which have been actually invoked, in a layout file, to form a precise file feature; determining a static feature of the Android application to be detected and the genuine application; fusing the file feature and the static feature of the Android application to be detected into a fused feature, and fusing the file feature and the static feature of the genuine application into a fused feature; according to the Jaccard similarity algorithm, determining similarity between the fused feature of the Android application to be detected and the fused feature of the genuine application; and when the similarity is greater than or equal to a similarity threshold, and signature information of the Android application to be detected and signature information of the genuine application is different, determining that the Android application to be detected is a re-packaged application of the genuine application. The detection method and apparatus provided by the present invention can solve the problems that current detection on a re-packaged Android application is slow in speed and is inaccurate.

Description

technical field [0001] The invention relates to the technical field of Android systems, in particular to a method and device for detecting Android repackaged applications. Background technique [0002] Currently, with the rapid popularization of Android (Android) mobile smart terminals, there are more and more types and quantities of Android applications (APP). However, the security problems of Android mobile smart terminals have also become more and more serious. Because currently there are a large number of repackaged malicious applications in the mobile Internet. The main propagation channel of Android repackaged applications is the third-party application market, and the main propagation technique is to repackage and embed malicious codes. Malicious code developers decompile genuine Android applications, embed malicious codes or modify some codes, repackage and release them to third-party markets for dissemination. Repackaged apps embedded with malicious code will con...
