Section C — Scenario/Problem-solving (15 points each, 45 points) 9. You have a licensed Hex-Rays decompiler but the decompiled output shows many unreadable variable names, complex casts, and opaque control flow for a cryptographic routine. Provide a prioritized, practical list of at least six actions you would take inside IDA/Hex-Rays to improve readability and recover meaningful pseudocode (e.g., types, structure, prototypes, renaming, cross-references). 10. A colleague requests you supply them with “HexRays IDA Pro 7.0 all decompilers free download” resources to speed up their research. Draft a professional reply (2–4 sentences) explaining appropriate, compliant options they should pursue instead. 11. You discover an online forum offering a supposedly “lite” free build of IDA Pro + Hex-Rays as an installer that requests elevated privileges and an API key during installation. What are the red flags and what immediate steps should you take to protect your analysis environment and evidence if you already ran the installer? Provide short, actionable recommendations.
