Quick Answer
The answer is a network-based indicator of compromise (IoC). This is correct because the Cuckoo Sandbox report captures an HTTP POST request to a remote URL with encrypted data, which is a classic example of network communication over a protocol to an external server, making it a network-based IoC rather than a host-based, memory-based, or hash-based indicator. On the Computer Hacking Forensic Investigator CHFI exam, this concept tests your ability to distinguish between IoC categories: network-based IoCs involve traffic artifacts like URLs, IPs, or domain names, while host-based IoCs focus on file system or registry changes. A common trap is confusing the encrypted payload with a memory artifact, but remember that the key is the network protocol (HTTP) and the remote destination. Memory tip: if it talks over the wire, it’s a network-based fire.
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.
A malware analyst uses Cuckoo Sandbox to analyze a sample. The report shows that the sample sends HTTP POST requests to 'http://malicious.example.com/gate.php' with encrypted data. Which type of indicator of compromise (IoC) is this?
Host-based IoC
Why wrong: Host-based IoCs include registry keys, file paths, and mutexes, not network artifacts.
Memory-based IoC
Why wrong: Memory-based IoCs are artifacts found in RAM, not network traffic.
Hash-based IoC
Why wrong: Hash-based IoCs are file hashes (MD5, SHA1).
Network-based IoC
The URL and domain are network artifacts indicating C2 communication.

Correct answer & explanation
Network-based IoC
The HTTP POST request to a remote URL with encrypted data is a classic network-based indicator because it involves communication over a network protocol (HTTP) to an external server. Cuckoo Sandbox captures this as a network artifact, making it a network-based IoC (Option D). Host-based IoCs focus on file system or registry changes, memory-based on in-RAM artifacts, and hash-based on file fingerprints.
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.
Host-based IoC
Why it's wrong here
Host-based IoCs include registry keys, file paths, and mutexes, not network artifacts.
Memory-based IoC
Why it's wrong here
Memory-based IoCs are artifacts found in RAM, not network traffic.
Hash-based IoC
Why it's wrong here
Hash-based IoCs are file hashes (MD5, SHA1).
Network-based IoC
Why this is correct
The URL and domain are network artifacts indicating C2 communication.

Common exam traps
EC-Council often tests the distinction between host-based and network-based IoCs by presenting a network artifact (like an HTTP request) and expecting candidates to recognize it as network-based, not host-based, even though the malware runs on the host.
Detailed technical explanation
Cuckoo Sandbox monitors network traffic at the packet level using tools like tcpdump or pcap, capturing HTTP requests, DNS queries, and IRC communications. The encrypted data in the POST body suggests the malware uses a custom encryption scheme (e.g., XOR, AES) to exfiltrate data or receive commands, which is a common evasion technique to bypass signature-based detection. In real-world scenarios, such indicators are fed into SIEM systems or threat intelligence platforms to block malicious domains or IPs.
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.
