VMSpec: A Decompiler-Based Approach against Virtual Machine Obfuscation

Malicious actors frequently obfuscate their code to hinder investigative reverse engineering efforts. Among the most formidable techniques is virtual machine VM obfuscation: programs are translated into bytecode for a custom VM, often with a randomized virtual instruction set and distributed...
