Quick Answer
The answer is Impacket’s wmiexec.py, the tool designed for pass-the-hash attacks to achieve remote code execution. This tool directly supports pass-the-hash authentication by accepting an NTLM hash via the `-hashes` flag, then leveraging Windows Management Instrumentation (WMI) to establish a remote session without needing the plaintext password. On the CompTIA PenTest+ PT0-002 exam, this scenario tests your understanding of lateral movement techniques—specifically how to use a captured local administrator hash to authenticate to another domain-joined system. A common trap is choosing tools like PsExec or Mimikatz for remote execution, but wmiexec.py is the correct choice because it natively integrates hash-based authentication over WMI, avoiding the need for service creation or interactive logon. Memory tip: think “WMI + hash = wmiexec” to recall that WMI’s remote management capability pairs directly with NTLM hashes for stealthy lateral movement.
This PT0-002 practice question tests your understanding of attacks and exploits. 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.
A penetration tester has obtained the NTLM hash of a local administrator account on a Windows domain-joined system. The tester wants to use this hash to authenticate to another system on the network and execute commands remotely. Which tool is commonly used for pass-the-hash attacks to achieve remote code execution?
Hydra
Why wrong: Hydra is a brute-force tool for online password guessing, not pass-the-hash.
Impacket's wmiexec.py
wmiexec.py authenticates via WMI using an NTLM hash, enabling remote command execution.
PsExec
Why wrong: PsExec can be used for remote execution but requires extra steps to pass the hash (e.g., using sekurlsa::pth).
Sqlmap
Why wrong: Sqlmap is used for exploiting SQL injection vulnerabilities, not for pass-the-hash attacks.

Correct answer & explanation
Impacket's wmiexec.py
Impacket's wmiexec.py is the correct tool because it directly supports pass-the-hash (PtH) authentication using NTLM hashes over Windows Management Instrumentation (WMI). It accepts an NTLM hash via the `-hashes` flag and establishes a remote WMI session, enabling command execution without needing the plaintext password. This makes it ideal for lateral movement in a domain environment where a local administrator hash has been captured.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Hydra
Why it's wrong here
Hydra is a brute-force tool for online password guessing, not pass-the-hash.
Impacket's wmiexec.py

PsExec
Why it's wrong here
PsExec can be used for remote execution but requires extra steps to pass the hash (e.g., using sekurlsa::pth).
Sqlmap
Why it's wrong here
Sqlmap is used for exploiting SQL injection vulnerabilities, not for pass-the-hash attacks.
Common exam traps
CompTIA often tests the distinction between tools that require plaintext credentials versus those that can operate directly with NTLM hashes, leading candidates to mistakenly choose PsExec because it is a well-known remote execution tool, even though it does not natively support pass-the-hash without additional credential injection steps.
Detailed technical explanation
Pass-the-hash works by leveraging the NTLM challenge-response protocol: the attacker supplies the captured NTLM hash as the response to the server's challenge, bypassing the need for the plaintext password. Impacket's wmiexec.py implements this by using the DCOM protocol to instantiate a WMI object on the remote system, then executing commands via the `Win32_Process` class. A subtle behavior is that this method works even if the remote system has UAC remote restrictions enabled, as long as the target account is a local administrator and the registry key `LocalAccountTokenFilterPolicy` is set to 1.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A penetration tester is attempting a pass-the-hash (PtH) attack against a Windows domain-joined machine. The tester has obtained the NTLM hash of a local administrator account. Which tool can be used directly to authenticate using the hash to gain remote command execution?
mediumWhy B: Metasploit's psexec module (exploit/windows/smb/psexec) directly accepts an NTLM hash via the 'SMBPass' option and uses it to authenticate over SMB, then creates a service on the target to execute commands. This is a classic pass-the-hash technique against Windows systems, as the module leverages the SMB protocol and Windows service control manager without needing the plaintext password.
