The correct answer is D because high entropy and the absence of readable strings are classic indicators that a sample may be packed, encrypted, or otherwise obfuscated. In static malware analysis, one of the first priorities in such a case is to identify the packing or obfuscation method so the analyst can understand how the file has been transformed and what additional unpacking or decoding steps may be needed. CHFI v11 includes static and dynamic malware analysis, analysis of suspicious files, and techniques for understanding malware structure before execution. Local or online malware scanning can provide reputation information, but it does not directly explain the structural concealment method. File fingerprinting identifies known samples, and strings analysis is useful, but the question already tells us that strings are scarce and entropy is high, making raw string extraction less informative. In forensic malware work, those clues point directly to packing or obfuscation. Therefore, the most appropriate static technique is to identify the packing or obfuscation methods used by the sample before any runtime testing begins.
