Description

These changes are by @eladshamir and just have been updated to match idiomatic changes.

Exposes Azure VM ID collection in SharpHound and attaches the result to collected computer objects.

• Adds AzureRegistry as a supported --collectionmethods value.
• Documents the method in the PowerShell collector help text.
• Uses the shared registry processor to retrieve an Azure VM guest ID.
• Adds successful results to computer properties as azvmid.
• Refactors registry-processor creation for reuse across registry-based collection methods.
• Updates the SharpHoundCommon package reference to 4.8.1.

AzureRegistry is available explicitly, through ComputerOnly, and through All; it is not enabled by the default collection set.

Motivation and Context

This PR addresses: BED-9763

How Has This Been Tested?

Walkthrough

The change adds AzureRegistry as a collection method and maps it to the runtime collection flag. Computer-object processing uses a cached registry processor to collect Azure registry data. When that data is marked collected, processing adds the VM ID to the computer object's azvmid property.

Changes

Azure Registry Collection

Layer / File(s)	Summary
Collection method option src/Client/Enums.cs, src/Options.cs, src/PowerShell/Template.ps1	The options enum, collection method resolution, and help text now include AzureRegistry. When Stealth is enabled, resolution removes that flag and records an update.
Computer registry processing src/Runtime/ObjectProcessors.cs	Computer processing uses a cached registry processor for NTLM and Azure registry collection. When Azure registry data is marked collected, processing adds its VM ID as azvmid.

AzureRegistry collection reaches out to all domain-joined computers to collect data via registry. This needs to fall under flags which normally execute this sort of collection. CodeRabbit has identified this similarly.
