WMI and WinRM

WMI

Windows Management Instrumentation (WMI), is an object-oriented feature for task automation. It communicates through RPC over port 135 and capable of creating processes.

WMI is capable of creating processes via the Create method from the Win32_Process class.

Remote process

To create a process on the remote target using WM it is required member of the Administrators local group.

Create a process using wmic:

wmic /node:<target> /user:<username> /password:<password> process call create "<command>"

Create a process using PowerShell:

$username = '<username>';
$password = '<password>';
$secureString = ConvertTo-SecureString $password -AsPlaintext -Force;
$credential = New-Object System.Management.Automation.PSCredential $username, $secureString;
$options = New-CimSessionOption -Protocol DCOM
$session = New-Cimsession -ComputerName <target> -Credential $credential -SessionOption $Options 
$command = '<command>';
Invoke-CimMethod -CimSession $Session -ClassName Win32_Process -MethodName Create -Arguments @{CommandLine =$Command};

WinRM

Windows Remote Management is Microsoft's implementation of the WS-Management protocol, used for remote host management. It exchanges XML-based messages over HTTP and HTTPS for secure communication.

WinRS

Windows Remote Shell is a command-line tool used for executing commands remotely on a Windows machine using the WinRM protocol. It allows administrators to manage remote systems securely, similar to SSH in Linux.

Usage:

winrs -r:<target> -u:<username> -p:<password> <command>

PS-Remoting

PowerShell Remoting allows for the remote execution of PowerShell commands and scripts on other Windows machines using the WinRM protocol. It supports interactive sessions.

The following requirements must be met to use PS-Remoting:

• PS-Remoting must be enabled on the target machine.

• The user must belong to either the Administrators group or the Remote Management Users group.

Usage:

$username = '<username>';
$password = '<password>';
$secureString = ConvertTo-SecureString $password -AsPlaintext -Force;
$credential = New-Object System.Management.Automation.PSCredential $username, $secureString;
PSSession -ComputerName <target> -Credential $credential
