GCIH Malware and AI-Assisted Investigations Practice Question
Exhibit
EXHIBIT:
{ "process_name": "svchost.exe", "parent_process": "powershell.exe", "network_conn": "192.168.1.105:443", "ai_analysis_score": 0.98, "threat_category": "suspicious_process_chain" }Refer to the exhibit. An AI-based EDR identifies a suspicious process chain. Based on the provided JSON output, what is the most appropriate next step for an incident handler?
⚠ Common exam trap
Candidates often rely purely on high-score AI heuristic alerts or automated verdicts, failing to perform the necessary manual verification of process memory and artifacts.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Examine process memory and network artifacts to confirm malicious injection.
The exhibit shows a clear anomaly where a parent-child relationship (PowerShell spawning svchost) is highly suspicious, especially when associated with an external connection. While the AI score is high, it is a heuristic indicator. The handler must verify this via manual inspection of the process memory and network artifacts to confirm if this is a legitimate system injection or a malicious beacon, ensuring that response actions are based on verified facts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Assume the alert is a false positive due to the common nature of svchost.
Why it's wrong here
Dismissing an alert involving PowerShell spawning svchost is dangerous. While svchost is common, it should never be spawned by PowerShell. This is a classic indicator of process injection or living-off-the-land techniques. A high AI score in this context strongly suggests malicious activity that requires immediate, thorough investigation rather than summary dismissal.
- ✗
Immediately isolate the host from the network based on the 0.98 AI score.
Why it's wrong here
Isolation is a disruptive action that should follow verification. While the score is high, an incident handler must perform quick validation to ensure the alert is not a misconfiguration or an authorized administrative task. Jumping straight to isolation without a basic check could cause unnecessary business disruption if the event is benign.
- ✓
Examine process memory and network artifacts to confirm malicious injection.
Why this is correct
Verification is mandatory. By analyzing the memory of the svchost instance and the network connection patterns, the responder confirms whether the process is indeed acting maliciously. This technical validation bridges the gap between an automated alert and actionable intelligence, allowing for a decisive and informed response to the identified threat.
- ✗
Restart the svchost service to terminate the suspicious connection.
Why it's wrong here
Restarting a service does not address the root cause and may destroy volatile evidence needed for forensic analysis. If the process is malicious, restarting it may lead to persistence mechanisms activating or the attacker simply re-infecting the host. Forensic integrity must be maintained before taking any action that alters system state.
