Abstract

The invention discloses a program evolution model-based object code reverse engineering system. An object code file packaging format can be automatically identified; an object code file code segment is distinguished; analysis is carried out by a disassembly technology and a corresponding program model is generated; analysis is carried out again and a new program model is generated on the basis of the previous program model; the processes are continuously repeated; and gradual refinement is carried out to finally generate an ASM reassemble file. By the program evolution model-based object code reverse engineering system, accurate and effective reverse engineering can be carried out on a self-confused object code file comprising instruction overlapping; the program evolution model-based object code reverse engineering system can be applied to analysis and identification of packed malicious software comprising a self-confusion instruction, instruction overlapping and the like and analysis of anti-disassembly closed-source software.

Description

technical field [0001] The invention relates to the field of data processing, in particular to an object code reverse engineering system based on a program evolution model. Background technique [0002] With the increase of software complexity, reverse engineering has attracted more and more attention, and has become a new branch in the field of software engineering. The purpose of using object code reverse engineering technology is to start directly from the compiled or specially processed final object program without source code, and apply various technical means to restore the semantic information of program behavior, thereby helping to understand the principle of the program. Analyzing malware, vulnerabilities of closed source software, interoperability of closed source software, consistency of target program with source program, verifying compiler performance and accuracy, and displaying assembly instructions during debugging are all target code reverse engineering tech...
