Sažetak
Analysis of malware binaries is constantly becoming more difficult with introduction of many different types of code obfuscators. One common theme in all obfuscators is transformation of code into a complex representation. This process can be viewed as inverse of compiler optimization techniques and as such can be partially removed using optimization algorithms. This paper presents common obfuscation techniques and a process of adapting optimization algorithms for removing obfuscations. Additionally, a plug-in for the IDA Pro disassembler is presented that demonstrates usability of the proposed optimization process as well as a set of techniques to speed up the process of analyzing obfuscated code.
