The answer is that the LNK file was planted by an attacker to mislead timeline analysis. This discrepancy arises because LNK files are normally generated automatically by the Windows shell when a user or process accesses a file via certain methods, such as double-clicking or using the Recent Items list, meaning the LNK creation timestamp should precede or match the file’s execution time. If the LNK creation time falls after the script’s known execution, it indicates the shortcut was not created by that access event but was instead manually placed or generated by malware to inject a false timeline entry and obscure the true sequence of compromise. On the CHFI exam, this tests your understanding of Windows artifact timestamps and timeline manipulation, a common trap where candidates assume all LNK files are automatically created; the key is remembering that LNK timestamps reflect file access, not necessarily file execution. Memory tip: “LNK after execution? Think ‘planted, not pointed.’”
CHFI OS and Network Forensics Practice Question
This CHFI practice question tests your understanding of os and network forensics. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 forensic analyst finds an LNK file on a Windows system pointing to a script located in a temporary folder. The LNK file's timestamps show creation time after the script's known execution time. What does this discrepancy likely indicate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The LNK file was planted by an attacker to mislead timeline analysis
LNK files are created when a file is accessed through certain methods; if the LNK creation time is after execution, it may have been created manually or by malware to hide evidence.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The system clock was changed
Why it's wrong here
Clock changes would affect all timestamps, not just LNK creation.
✗
The file system is corrupted
Why it's wrong here
Corruption would cause more widespread anomalies.
✓
The LNK file was planted by an attacker to mislead timeline analysis
Why this is correct
An attacker may create a backdated or post-dated LNK to confuse forensic timelines.

✗
The script was executed normally
Why it's wrong here
Normal execution would create the LNK at or before execution.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
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 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.
