The correct answer includes the hybrid attack, which combines dictionary and brute-force methods to efficiently crack passwords that append or prepend characters to a known word list. Hashcat supports this as one of its primary attack modes, alongside pure brute-force and dictionary attacks, by first testing a wordlist and then systematically appending or prepending characters from a defined keyspace. On the Certified Ethical Hacker CEH exam, this question tests your understanding of how GPU-accelerated tools like Hashcat optimize cracking strategies; a common trap is confusing hybrid attacks with simple brute-force or rule-based attacks. Remember that a hybrid attack is essentially a dictionary attack with a brute-force suffix or prefix, making it more targeted than a full brute-force but broader than a plain dictionary run. A useful memory tip: think of “hybrid” as “dictionary plus brute-force append” — if you see a password like “Summer2024!”, the base word comes from a dictionary, and the year and symbol are brute-forced additions.
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 password cracking techniques that can be used with Hashcat? (Select 3)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Brute-force attack
Hashcat is a GPU-accelerated password recovery tool that supports multiple attack modes. A brute-force attack (option B) systematically tries every possible combination of characters from a defined keyspace until the correct password is found. Hashcat implements this via its '?a' mask or direct brute-force mode, making it a core technique for cracking hashes when no prior knowledge of the password exists.
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.
✗
Token impersonation
Why it's wrong here
Token impersonation is a privilege escalation technique, not a password cracking method.
✓
Brute-force attack
Why this is correct
Hashcat can perform brute-force attacks by iterating through all possible character combinations.

✗
Rainbow table attack
Why it's wrong here
Rainbow table attacks are not natively supported by Hashcat; they are used by RainbowCrack.
✓
Dictionary attack
Why this is correct
Hashcat supports dictionary attacks using a wordlist file.

✓
Hybrid attack
Why this is correct
Hashcat supports hybrid attacks that combine a wordlist with brute-force suffixes or prefixes (e.g., mask attacks).

Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the misconception that rainbow table attacks are a core Hashcat feature, but Hashcat does not implement rainbow tables; it uses GPU-accelerated brute-force, dictionary, and hybrid modes instead.
Detailed technical explanation
How to think about this question
Hashcat's hybrid attack (option E) combines dictionary words with brute-force rules (e.g., appending digits or symbols) to efficiently crack passwords that follow common patterns like 'password123'. The tool uses OpenCL or CUDA to parallelize hash computations across thousands of GPU cores, achieving billions of attempts per second for fast hashes like NTLM or MD5. Real-world scenarios often involve cracking Active Directory NTLM hashes where a hybrid attack can recover passwords that a pure dictionary would miss but a full brute-force would take too long.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
