Camouflage in Malware: From Encryption to Metamorphism

Camouflage of malware is a serious challenge for antivirus experts and code analysts. Malware use various techniques to camouflage them to not be easily visible and make their lifetime as longer as possible. Although, camouflage approaches cannot fully stop the analyzing and fighting against the malware, but it make the process of analyzing and detection prolonged, so the malware can get more time to widely spread.
