CEH Enumeration and System Hacking Practice Question
This CEH practice question tests your understanding of enumeration and system hacking. 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.
Which THREE of the following are valid techniques for covering tracks after compromising a system? (Select 3 correct answers)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Clearing event logs using wevtutil
A is correct because wevtutil is a Windows command-line utility used to manage event logs. After compromising a system, an attacker can use 'wevtutil cl' followed by a log name (e.g., 'wevtutil cl System') to clear specific event logs, thereby erasing evidence of their activities. This is a direct and common technique for covering tracks by removing forensic artifacts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Clearing event logs using wevtutil
Why this is correct
Clearing logs removes evidence of activity.

✗
Exploiting SUID binaries to gain root
Why it's wrong here
This is privilege escalation, not covering tracks.
✓
Installing a rootkit to hide malicious processes
Why this is correct
Rootkits conceal processes and files from detection.

✓
Using timestomp to modify file timestamps
Why this is correct
Timestomp changes file creation/modification times to blend in.

✗
Disabling Windows Defender via Group Policy
Why it's wrong here
Disabling security software is more about evasion than covering tracks after compromise.
Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the distinction between privilege escalation (gaining higher access) and covering tracks (hiding evidence), causing candidates to mistakenly select SUID exploitation as a track-covering technique.
Detailed technical explanation
How to think about this question
Covering tracks involves actions like clearing logs, modifying timestamps, and hiding malicious processes to avoid detection by system administrators or forensic tools. Timestomp (option D) modifies file timestamps (e.g., creation, modification, access times) using tools like the Metasploit timestomp module or the Windows 'fsutil' command, making malicious files appear legitimate. Rootkits (option C) operate at the kernel level to intercept system calls (e.g., sysfs, procfs) and hide processes, files, or registry keys from user-mode tools like Task Manager or 'ps'.
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.
TExam Day Tips
→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 CEH 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.
