Offensive WMI
Windows Management Instrumentation (WMI) is a powerful feature of the Windows operating system that provides a standardized interface for accessing and managing various components of a computer. It is extensively used for administrative purposes, but its capabilities can also be leveraged for offensive security purposes, making it a valuable tool for red teamers.
Why WMI is Useful for Red Teaming
Remote Management: WMI allows for the execution of commands and scripts on remote systems, facilitating lateral movement within a network without the need for additional tools.
Stealth and Evasion: WMI operates using legitimate Windows processes, making it less likely to trigger security alerts compared to traditional malware or hacking tools.
Automation and Scripting: WMI can be scripted using languages such as PowerShell or VBScript, enabling the automation of complex tasks and reducing manual intervention.
Extensive Functionality: WMI can interact with various system components, such as file systems, registry, processes, services, and network settings, providing comprehensive control over the target environment.

Examples and Usage
Example 1: Querying System Information
This script queries detailed information about the operating system on the target machine.
Example 2: Executing a Remote Command
This script creates a new process (Notepad) on the target machine using WMI.
Example 4: Enumerating Running Processes
This script lists all running processes on the target machine.
This script uses WMI to query the Win32_Process
class on the target machine and retrieves information about running processes, including the process name, process ID, and command line.
Conclusion
Using WMI for offensive purposes allows red teamers to execute commands, create persistence mechanisms, and gather valuable information from target machines while maintaining a low profile. These examples demonstrate the versatility of WMI in red teaming scenarios, highlighting its potential for stealthy and efficient operations.
