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.
An analyst is performing malware analysis and executes a suspicious binary in a sandbox. The sandbox reports that the binary creates a mutex named 'Global\DRIVER_UPDATE_MTX' before attempting to connect to 'http://malicious.com/update'. Which tool would BEST capture the network traffic during dynamic analysis?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Regshot
Why wrong: Regshot compares registry snapshots before and after execution, not network traffic.
Wireshark
Wireshark captures and analyzes network packets, ideal for monitoring C2 traffic.
Process Explorer
Why wrong: Process Explorer provides detailed process information but does not capture network packets.
Process Monitor
Why wrong: Process Monitor captures file system, registry, and process activity, not network traffic.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Wireshark
Wireshark is the correct tool because it captures and analyzes network packets at the protocol level, allowing the analyst to inspect the HTTP request to 'http://malicious.com/update', including headers, payload, and any subsequent data exfiltration. Dynamic analysis of malware requires monitoring network traffic to identify command-and-control (C2) communications, and Wireshark provides full packet capture (PCAP) for this purpose.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Regshot
Why it's wrong here
Regshot compares registry snapshots before and after execution, not network traffic.
Wireshark
Why this is correct
Wireshark captures and analyzes network packets, ideal for monitoring C2 traffic.
Clue confirmation
The clue word "best" in the question point toward this answer.

Process Explorer
Why it's wrong here
Process Explorer provides detailed process information but does not capture network packets.
Process Monitor
Why it's wrong here
Process Monitor captures file system, registry, and process activity, not network traffic.
Common exam traps
EC-Council often tests the distinction between host-based monitoring tools (like Process Monitor and Process Explorer) and network-based capture tools (like Wireshark), leading candidates to choose a host-based tool when the question explicitly asks for network traffic capture.
Detailed technical explanation
Wireshark uses the libpcap/WinPcap library to capture raw network frames from the network interface card (NIC), allowing it to reconstruct TCP streams and decode application-layer protocols like HTTP. In a sandbox environment, the analyst can filter for HTTP traffic using 'http.request' or 'tcp.port == 80' to isolate the malicious connection. A real-world scenario might involve the malware using HTTPS to evade detection, requiring Wireshark to capture the TLS handshake and encrypted payload, which can then be decrypted if the analyst has the private key or uses a man-in-the-middle proxy.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
