How to Use CrackMapExec to Dump Windows Password Hashes
CrackMapExec is a powerful tool that allows you to perform various attacks and operations on Windows networks, such as enumeration, execution, credential dumping, lateral movement, and more. One of the most useful features of CrackMapExec is the ability to dump Windows password hashes from the local Security Accounts Manager (SAM) database or the LSA memory.
Windows password hashes can be used for various purposes, such as cracking them offline, passing them to other services or systems, or relaying them to other hosts. In this article, we will show you how to use CrackMapExec to dump Windows password hashes from different sources and methods.

How to Use CrackMapExec to Dump Windows Password Hashes
To use CrackMapExec to dump Windows password hashes, you need to have the following requirements:
A Linux system with CrackMapExec installed. You can install it from https://github.com/Porchetta-Industries/CrackMapExec or use the official Docker image.
A valid username and password or a password hash of a Windows user with administrative privileges on the target system or domain.
A network connection to the target system or domain.
Once you have these requirements, you can use the following steps to dump Windows password hashes using CrackMapExec:
Launch CrackMapExec with the smb protocol and the target IP address or subnet. You also need to specify the username and password or hash of the Windows user with administrative privileges. For example:
crackmapexec smb 192.168.1.10 -u Administrator -p 'P@ssw0rd'
crackmapexec smb 192.168.1.0/24 -u Administrator -H 'LMHASH:NTHASH'
If the connection is successful, you will see a green plus sign (+) next to the target IP address and some information about the system and domain.
To dump the local SAM hashes, use the --sam option. This will extract the hashes of all local users on the target system. For example:
crackmapexec smb 192.168.1.10 -u Administrator -p 'P@ssw0rd' --sam
To dump the LSA memory hashes, use the --lsa option. This will extract the hashes of all users that have logged on to the target system since the last reboot. However, this option requires that WDigest is enabled on the target system. You can enable it using the --wdigest enable option, but this will require a logoff and logon of the user to take effect. For example:
crackmapexec smb 192.168.1.10 -u Administrator -p 'P@ssw0rd' --wdigest enable
crackmapexec smb 192.168.1.10 -u Administrator -p 'P@ssw0rd' --lsa
The dumped hashes will be displayed on the screen and also saved in a file called cme-hashes.db in your current directory. You can use this file for further analysis or cracking.
Conclusion
By following these steps, you can use CrackMapExec to dump Windows password hashes from different sources and methods. This can help you gain access to other systems or services on the network or crack the passwords offline using tools like John the Ripper or Hashcat.
