Question

What is the benefit of using metamorphism in malware?

a.

It makes the program run faster

b.

It encrypts the program's body and makes slight alterations in the decryption engine

c.

It makes each version of the malware look radically different from any other versions

d.

It makes the program more easily identifiable by antivirus programs

Posted under Reverse Engineering

Answer: (c).It makes each version of the malware look radically different from any other versions Explanation:The benefit of metamorphism (from a malware writer’s perspective) is that each version of the malware can look radically different from any other versions. This makes it very difficult (if not impossible) for antivirus writers to use any kind of signature-matching techniques for identifying the malicious program.
