Explore a generic approach to automatic deobfuscation of executable code in this 20-minute IEEE conference talk. Delve into techniques for penetrating and removing obfuscations in malicious software to understand internal logic and develop countermeasures. Learn about semantics-preserving program transformations that simplify obfuscation code without making assumptions about specific obfuscation methods. Discover how this approach has been applied to various obfuscation types, including emulation-based obfuscation with runtime code unpacking and return-oriented programming. Examine the effectiveness of this method in extracting internal logic from code obfuscated using tools like Themida, which previous approaches struggled to handle. Cover topics such as change analysis, control dependencies, simplifying transformations, emulation, and CFG comparison through a comprehensive syllabus.
