- A
The user double-clicked a PowerShell script attached to the email
Why wrong: The parent process is winword.exe, not an email client, so the script was launched from within Word.
- B
The document contains a malicious macro that spawned PowerShell to execute commands
Attackers often use macros in Office documents to launch PowerShell for code execution.
- C
A scheduled task started PowerShell that initiated Word
Why wrong: This would show scheduled task as parent, not Word.
- D
The user is running a legitimate PowerShell script from within a Word document
Why wrong: While possible, it is unlikely in a security context; the typical scenario is malicious macro activity.

Correct answer & explanation
✓
The document contains a malicious macro that spawned PowerShell to execute commands
This is a classic sign of a macro-based attack where a malicious document spawns PowerShell to execute payloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

This would show scheduled task as parent, not Word.
Scenario analysis trap
While possible, it is unlikely in a security context; the typical scenario is malicious macro activity.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
