Abstract

The invention provides an application program shelling method and device, and provides a common code shelling scheme. The method comprises the steps of loading the shelled Dex code of an application program to be unshelled into a memory using an Android virtual machine DVM; locating the memory fragment of the corresponding Dex code of the target class for a target class of the application program to be unshelled; loading actively the Dex code in the memory fragment into the memory object used by the DVM at active loading time, wherein the active loading time is the time after all of the shell-added Dex code are loaded into the memory and before the running of the Dex code in the memory is over; restoring the Dex code in the memory object to the unshelled Dex code corresponding to the target class, and generating a Dex file containing the unshelled Dex code.

Description

technical field [0001] The present application relates to the technical field of software, and in particular to an application program unpacking method and device. Background technique [0002] In order to prevent the code of the application (Application, APP) from being disassembled or cracked, it is generally necessary to pack the code of the APP. With the development of the mobile Internet, some malicious apps also use packing technology, making it difficult for security analysts to successfully identify malicious apps. For this reason, there is currently a demand for unpacking the packer codes of various packer apps. Currently, there are various rules for packing APP codes, and there is no general unpacking solution. Contents of the invention [0003] In order to overcome the problems existing in the related technologies, the embodiments of the present application provide an application unpacking method and device. [0004] According to the first aspect of the embod...
