The correct answer is that static analysis examines code without execution, while dynamic analysis executes the sample. This distinction is fundamental because static analysis focuses on the malware’s structure—disassembling its code, extracting strings, and inspecting headers—to understand its intent without ever running the file, whereas dynamic analysis observes the malware’s runtime behavior in a controlled sandbox or debugger, revealing actions like file modifications or network connections that static analysis cannot capture. On the Computer Hacking Forensic Investigator CHFI exam, this question tests your ability to differentiate between these two core forensic methodologies, often appearing as a straightforward concept check; a common trap is confusing static analysis with dynamic by assuming both involve execution, or misidentifying which technique reveals behavioral artifacts. To remember the difference, think of static as “still” and dynamic as “doing”—static reads the blueprint, dynamic watches the building move.
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 and dynamic malware analysis?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Static analysis examines code without execution, dynamic analysis executes the sample
Static malware analysis involves examining the malware's code (e.g., disassembly, strings, headers) without executing it, while dynamic analysis runs the sample in a controlled environment (e.g., sandbox, debugger) to observe its runtime behavior. Option C correctly captures this fundamental distinction: static analysis is code-centric and non-executional, whereas dynamic analysis is behavior-centric and executional.
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 executes the malware, dynamic does not
Why it's wrong here
It's the opposite: dynamic executes, static does not.
✗
Static analysis requires an internet connection, dynamic does not
Why it's wrong here
Neither inherently requires internet; dynamic may simulate network services.
✓
Static analysis examines code without execution, dynamic analysis executes the sample
Why this is correct
Static involves disassembly and code review; dynamic involves running the malware.
Related concept
Read the scenario before looking for a memorised answer.
✗
Static analysis is always automated, dynamic is manual
Why it's wrong here
Both can be automated or manual.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the terms 'static' and 'dynamic' by associating 'static' with 'not moving' (incorrectly thinking it means no analysis) or misremembering which one involves execution, leading them to pick Option A.
Detailed technical explanation
How to think about this question
Under the hood, static analysis leverages tools like IDA Pro or Ghidra to parse PE headers (e.g., IMAGE_FILE_HEADER, IMAGE_OPTIONAL_HEADER) and extract import/export tables, while dynamic analysis uses API monitoring (e.g., via Detours or API Monitor) to capture calls like CreateProcess or WriteFile at runtime. A real-world scenario: a zero-day ransomware sample might evade static signature detection by obfuscating strings, but dynamic analysis can reveal its file encryption behavior by monitoring file system activity in a sandboxed VM.
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.
