What is the purpose of using Obfuscator in malware?

The correct answer is C. Avoid detection by security mechanisms. An obfuscator transforms malware code into a functionally equivalent but structurally different form - renaming variables, inserting junk code, encrypting strings, or reordering instructions - to make it unrecognizable to signature-based antivirus engines, YARA rules, and…

Explanation

An obfuscator transforms malware code into a functionally equivalent but structurally different form - renaming variables, inserting junk code, encrypting strings, or reordering instructions - to make it unrecognizable to signature-based antivirus engines, YARA rules, and static analysis tools. The malware still executes the same malicious logic, but its appearance changes enough to bypass detection. Execution of malicious code is the payload's job, VPN bypass relates to tunneling tools, and propagation is the role of worm/spreading modules - obfuscation is specifically about evasion.
