New AzureArc Module

Description

Enumerates Azure Arc presence on Windows targets and, when present, retrieves a Managed Identity access token from the local Arc IMDS endpoint using the documented 401 challenge → .key file → second request flow.

• Protocol: SMB (requires local administrator privileges)
• Primary use case: Rapidly map Arc deployment and obtain a cloud-scoped token for Azure control-plane enumeration during red team engagements.

Thanks for the PR! Very interesting!

Can you add a guide for setting up the machine to test the module on? To be specific, it helps a lot if there is some kind of guide what i have to install etc. so that necessary services/files etc are available so the module actually does something.

Of course, for the service to run properly, you’ll need to run a PowerShell script provided by Azure when onboarding your machine (it must be an on-premises machine, not an Azure VM) to your tenant in Azure. To do this, follow these steps:

1. Search for 'Azure Arc' in the searching bar in Azure Portal

2. Add a machine

3. Add a single server

4. Fill in the details of the resource group where the deployed machine will be located, then click “Download and run script"

5. Download/Copy the content of the provided "OnboardingScript.ps1" script:

6. Run the script in PowerShell with local administrator permissions. During the installation, an agent package will be downloaded and installed from Azure.com. You’ll then be prompted to authenticate at login.microsoftonline.com using an Azure account with the appropriate permissions to perform this action:

7. Once the machine successfully added, you can run the new NetExec AzureArc Module
