Efficiency Improvement in Code Emulation by Soft Computing Technique

Abstract

Cyber espionage is an illicit way of obtaining secrets or information without user’s knowledge. Today, the Stuxnet, Duqu and flame computer worms which are used as cyber weapons against nations continue to make headlines as a new breed of malware. Understanding this topic is important to know how technology shapes the world and influences nation-state relation. It can be in different ways, malicious software like malware- a threat to system security. The technique of malware analysis either in sophistication of samples analyzed through the traditional approaches has its own con’s (Zero day Vulnerability). The aim of this paper is to analyze metamorphic virus using code emulation and implementation of few simple parameters by using fuzzy logic. We also justified how and why these parameters are considered. For a brief introduction to this paper, we used code emulator which creates a virtual environment where we considered number of iterations, memory access function and size of the virus as the performance metrics. The point of code emulation is to mimic the instruction set of CPU using virtual registers and flags.
