Explanation

This query is looking for instances when a download URL is generated for an Azure virtual machine disk. It uses the Azure Activity data connector and filters for operations with the name "MICROSOFT.COMPUTE/DISKS/BEGINGETACCESS/ACTION" and a status of "Success". It then extends the query to include the disk name and projects specific columns such as time generated, actor (caller), actor IP address, Azure subscription ID, and Azure resource group.
