Goal
Detect when an Azure disk is successfully exported. Export URLs generated in Azure are accessible to anyone with the URI. This could be utilized as an exfiltration method that would allow an attacker to download an Azure Compute VM’s disk as a VHD file.
Strategy
Monitor Azure logs where @evt.name is "MICROSOFT.COMPUTE/DISKS/BEGINGETACCESS/ACTION" and @evt.outcome is Success.
Triage and response
- Verify the disk (
{{@resourceId}}) has a legitimate reason for being exported. - If the activity is not expected, investigate the activity around the IP (
{{@network.client.ip}}) creating the export URI.
Changelog
2 November 2022 - Updated strategy.
