The answer is Hashcat, the best choice for GPU hash cracking NTLM hashes due to its native support for GPU acceleration via OpenCL or CUDA, which parallelizes the cracking process across thousands of cores for maximum speed. When targeting NTLM hashes, Hashcat uses the `-m 1000` mode, allowing it to process large dumps from a Windows Domain Controller far faster than CPU-bound tools. On the CompTIA PenTest+ PT0-002 exam, this question tests your understanding of specialized password cracking tools and their hardware acceleration capabilities; a common trap is choosing John the Ripper, which can use GPUs but requires complex configuration and is generally slower for NTLM, or Ophcrack, which only handles LM hashes. Remember the mnemonic: "Hashcat Hacks Hashes Harder with Hardware"—if the task demands speed on NTLM, Hashcat’s GPU mode is the definitive answer.
PT0-002 Tools and Code Analysis Practice Question
This PT0-002 practice question tests your understanding of tools and code analysis. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 penetration tester has obtained a dump of NTLM password hashes from a Windows Domain Controller. The tester wants to crack these hashes as quickly as possible using GPU acceleration. Which tool is the BEST choice for this task?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Why wrong: John the Ripper supports NTLM cracking but does not utilize GPU acceleration by default; it is generally slower than Hashcat for this purpose.
B
Hashcat
Hashcat is designed for high-speed password cracking with GPU support; it is the fastest tool for NTLM hashes when a compatible GPU is available.
C
Ophcrack
Why wrong: Ophcrack is specialized for LM hash cracking and uses rainbow tables; it does not support NTLM hashes.
D
THC-Hydra
Why wrong: THC-Hydra is an online password brute-forcing tool for network services, not an offline hash cracker.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Hashcat
Hashcat (Option B) is the best choice because it is specifically designed for GPU-accelerated password cracking, supporting NTLM hashes with the -m 1000 mode. It leverages OpenCL or CUDA to parallelize cracking across thousands of GPU cores, making it significantly faster than CPU-based tools for large hash dumps. John the Ripper can use GPUs but requires additional configuration and is generally slower for NTLM hashes, while Ophcrack is limited to LM hashes and cannot handle NTLM hashes at all.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume John the Ripper is the universal cracking tool due to its popularity, overlooking that Hashcat is the industry standard for GPU-accelerated NTLM cracking because of its optimized kernel and native support for the NTLM hash mode (-m 1000).
Detailed technical explanation
How to think about this question
NTLM hashes are stored as unsalted MD4 digests of the UTF-16LE encoded password, making them vulnerable to fast dictionary and brute-force attacks. Hashcat's kernel exploits this by computing the MD4 hash directly on the GPU, achieving rates of billions of hashes per second on modern hardware. In a real-world engagement, a tester might use Hashcat with rules and masks to crack weak passwords within minutes, whereas John the Ripper would take hours for the same workload.

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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
