## How It Works Explained
|
|
|
|
Processes can be opened on hosts where the username and either password or hash are known through the use of WMI. Commands are executed using WMI by Wmiexec, providing a semi-interactive shell experience.
|
|
|
|
**dcomexec.py:** Utilizing different DCOM endpoints, this script offers a semi-interactive shell akin to wmiexec.py, specifically leveraging the ShellBrowserWindow DCOM object. It currently supports MMC20. Application, Shell Windows, and Shell Browser Window objects. (source: [Hacking Articles](https://www.hackingarticles.in/beginners-guide-to-impacket-tool-kit-part-1/))

## WMI Fundamentals
|
|
|
|
### Namespace
|
|
|
|
Structured in a directory-style hierarchy, WMI's top-level container is \root, under which additional directories, referred to as namespaces, are organized.
|
|
Commands to list namespaces:
|
|
|
|
```bash
|
|
# Retrieval of Root namespaces
|
|
gwmi -namespace "root" -Class "__Namespace" | Select Name
|
|
|
|
# Enumeration of all namespaces (administrator privileges may be required)
|
|
Get-WmiObject -Class "__Namespace" -Namespace "Root" -List -Recurse 2> $null | select __Namespace | sort __Namespace
|
|
|
|
# Listing of namespaces within "root\cimv2"
|
|
Get-WmiObject -Class "__Namespace" -Namespace "root\cimv2" -List -Recurse 2> $null | select __Namespace | sort __Namespace
|
|
```
|
|
|
|
Classes within a namespace can be listed using:
|
|
|
|
```bash
|
|
gwmwi -List -Recurse # Defaults to "root\cimv2" if no namespace specified
|
|
gwmi -Namespace "root/microsoft" -List -Recurse
|
|
```
|
|
|
|
### **Classes**
|
|
|
|
Knowing a WMI class name, such as win32\_process, and the namespace it resides in is crucial for any WMI operation.
|
|
Commands to list classes beginning with `win32`:
|
|
|
|
```bash
|
|
Get-WmiObject -Recurse -List -class win32* | more # Defaults to "root\cimv2"
|
|
gwmi -Namespace "root/microsoft" -List -Recurse -Class "MSFT_MpComput*"
|
|
```
|
|
|
|
Invocation of a class:
|
|
|
|
```bash
|
|
# Defaults to "root/cimv2" when namespace isn't specified
|
|
Get-WmiObject -Class win32_share
|
|
Get-WmiObject -Namespace "root/microsoft/windows/defender" -Class MSFT_MpComputerStatus
|
|
```
|
|
|
|
### Methods
|
|
|
|
Methods, which are one or more executable functions of WMI classes, can be executed.
|
|
|
|
```bash
|
|
# Class loading, method listing, and execution
|
|
$c = [wmiclass]"win32_share"
|
|
$c.methods
|
|
# To create a share: $c.Create("c:\share\path","name",0,$null,"My Description")
|
|
```
|
|
|
|
```bash
|
|
# Method listing and invocation
|
|
Invoke-WmiMethod -Class win32_share -Name Create -ArgumentList @($null, "Description", $null, "Name", $null, "c:\share\path",0)
|
|
```
|
|
|
|
## WMI Enumeration
|
|
|
|
### WMI Service Status
|
|
|
|
Commands to verify if the WMI service is operational:
|
|
|
|
```bash
|
|
# WMI service status check
|
|
Get-Service Winmgmt
|
|
|
|
# Via CMD
|
|
net start | findstr "Instrumentation"
|
|
```
|
|
|
|
### System and Process Information
|
|
|
|
Gathering system and process information through WMI:
|
|
|
|
```bash
|
|
Get-WmiObject -ClassName win32_operatingsystem | select * | more
|
|
Get-WmiObject win32_process | Select Name, Processid
|
|
```
|
|
|
|
For attackers, WMI is a potent tool for enumerating sensitive data about systems or domains.
|
|
|
|
```bash
|
|
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
|
|
```
|
|
|
|
Remote querying of WMI for specific information, such as local admins or logged-on users, is feasible with careful command construction.
|
|
|
|
### **Manual Remote WMI Querying**
|
|
|
|
Stealthy identification of local admins on a remote machine and logged-on users can be achieved through specific WMI queries. `wmic` also supports reading from a text file to execute commands on multiple nodes simultaneously.
|
|
|
|
To remotely execute a process over WMI, such as deploying an Empire agent, the following command structure is employed, with successful execution indicated by a return value of "0":
|
|
|
|
```bash
|
|
wmic /node:hostname /user:user path win32_process call create "empire launcher string here"
|
|
```
|
|
|
|
This process illustrates WMI's capability for remote execution and system enumeration, highlighting its utility for both system administration and penetration testing.
