CHFI Mobile and Malware Forensics Practice Question
This CHFI practice question tests your understanding of mobile and malware forensics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which of the following is a key difference between static analysis and dynamic analysis in malware forensics?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Static analyzes the code without execution; dynamic executes the malware.
Option D is correct because static analysis involves examining the malware's code (e.g., disassembly, string extraction, hash analysis) without executing it, while dynamic analysis runs the malware in a controlled sandbox environment to observe its runtime behavior, such as file system changes, registry modifications, and network connections. This fundamental distinction is critical in malware forensics to safely understand the threat without risking infection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Static analysis requires the malware to be executed, while dynamic analysis does not.
Why it's wrong here
This is the opposite.
✗
Static analysis is used only for packed malware, while dynamic analysis is used for unpacked.
Why it's wrong here
Both can be used for any type; static may be hindered by packing.
✗
Dynamic analysis uses tools like IDA Pro, while static uses Cuckoo Sandbox.
Why it's wrong here
IDA Pro is for static; Cuckoo is for dynamic.
✓
Static analyzes the code without execution; dynamic executes the malware.
Why this is correct
Correct distinction.

Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the reversal of definitions (execution vs. non-execution) to catch candidates who confuse static and dynamic analysis roles.
Detailed technical explanation
How to think about this question
Under the hood, static analysis often uses signature-based detection (e.g., YARA rules) and entropy analysis to identify packed sections, while dynamic analysis relies on API hooking (e.g., using Detours or Microsoft's Detours library) to intercept calls like NtCreateFile or socket() at runtime. A real-world scenario where this matters is analyzing a polymorphic malware that changes its code on each execution: static analysis may miss variants, but dynamic analysis captures the actual behavior in the sandbox.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
