Which component generates randomized decryption routines to bolster polymorphism?

• A. Mutation engine
• B. Decryptor routine
• C. Polymorphic viruses
• D. System Sector Virus

Answer: (B)

Polymorphism relies on a mutation engine that generates randomized decryption routines, producing different decryptor stubs for each infection while keeping the payload the same. This variability makes static signatures less reliable because each variant looks different at the code level, even though its decryption behavior remains identical. The decryptor routine itself is the code that actually performs decryption, but it’s the mutation engine that creates new, varied decryptors.
