Abstract

The invention discloses an application program encasing method, which comprises the following steps: copying an executable file into a memory, splitting sections to extract a resource table, modifyinga PE head, integrating other sections into one section, placing the sections together and encrypting, adding three sections A, B and C, wherein the later two are used for storing encasing codes and repairing repositioning tables thereof, and the first is used for storing a code checking module; the second one is used for repairing the running environment of the shelled program; and the third oneis used for decompressing each segment, organizing the data of the segment A into a dll file and loading the dll file.

Description

technical field

[0001] The invention relates to the technical field of computers, in particular to a method for packing application programs. Background technique

[0002] Packing is a method of changing the encoding of executable program files or dynamic link library files through a series of mathematical operations to achieve the purpose of reducing file size or encrypting program encoding. Existing packing products include compressed shells such as Upx and ASpack, such as encrypted shells such as patents CN201110437932.9 and CN201310648196.0.

[0003] However, compressed shells such as Upx and ASpack cannot prevent ida static analysis, and the encrypted shells disclosed in patents CN201110437932.9 and CN201310648196.0 do not have compressed codes, and the file size after packing is too large. Therefore it is necessary to study a scheme to solve the above problems. Contents of the invention

[0004] In view of this, the present invention addresses the shortcomings ...
