Correct answer & explanation

✓

Script Block Logging (Event ID 4104) captures the full, de-obfuscated script content, making it the gold standard for PowerShell analysis.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Disk forensic analysis of the user's browser history
Why it's wrong here
Browser history is irrelevant for fileless PowerShell execution.
✓
Windows Event Log - PowerShell Script Block Logging (Event ID 4104)
Why this is correct
Event ID 4104 records the full content of executed PowerShell blocks, including dynamically generated commands.
✗
Windows Security Log - Process Creation (Event ID 4688)
Why it's wrong here
4688 records the command line, but it is limited in length and often misses obfuscated or long scripts.
✗
Network firewall traffic logs for port 5985
Why it's wrong here
Firewall logs show connection attempts but not the content of the commands executed.
