🧩 Lumma Stealer: A Deep Dive into Malware Deobfuscation Techniques. The article details the author’s journey in developing a Hex-Rays plugin to deobfuscate Lumma Stealer, a prevalent infostealer malware. Initially, the malware employed simple obfuscation techniques, but it evolved to include complex methods like control flow flattening and opaque predicates. The author faced numerous challenges, including handling optimization blocks and complex branches, ultimately leading to a successful deobfuscation of over 50 functions. The project not only highlights the intricacies of malware analysis but also emphasizes the importance of community knowledge sharing, as the author credits Rolf Rolles for his foundational work. Future enhancements may include a microcode emulator and a profile system for improved analysis.
