Which component is used to conceal a malware payload by transforming the code to hinder detection?

• A. Dropper
• B. Obfuscator
• C. Injector
• D. Packer

Answer: (B)

Transforming the code to hinder detection is the job of an obfuscator. An obfuscator alters the program’s appearance and structure while preserving its behavior, making it harder for defenders to recognize the payload or understand what it does. Techniques include renaming variables to meaningless strings, flattening or twisting control flow, inserting dummy or opaque code paths, and encoding or encrypting strings so that static analysis and signature-based detection can’t readily match known malicious patterns. The goal is to conceal the true intent and logic behind the malware, forcing analysts to invest more time and effort to reverse it. While other components can contribute to hiding a payload—such as packing, which compresses and then unpacks code at runtime, or droppers, which deliver the payload to the system, or injectors, which insert code into another process—the emphasis here is on deliberately transforming the code to evade detection. That focus on code transformation to confuse analysis and bypass defenses is what defines the obfuscator.
