When a Zero day malware crops up and with the advent of polymorphism and obfuscation, such malware poses a serious threat to unsuspecting victims of such attack. In this paper we will analyze the current scenario of such a malware threat that is obfuscated and polymorphic in nature against different malware analysis tools employing different techniques. A mutation engine is created to create the obfuscated polymorphic key logger malware. On a positive note, however, the obfuscation technique can also be used to make softwares that are less vulnerable from unwanted distribution.
