In order to avoid being static analyzed, hacker rely on various obfuscation techniques to hide its malicious characters. These techniques are very effective against common disassembles, preventing binary file from being disassembled correctly. The study presents novel disassemble algorithm which based on analyzed Control Flow Graph (CFG) and Data Flow Graph (DFG) information improve the ability of the disassembly. The proposed algorithm was verified on varied binary files. The experiment shows that the method not only improves the accuracy of disassemble but also greatly deal with malicious files.
