Microsoft Defender for Cloud
Cloud and workloadsRelease Notes
In brief
Microsoft Defender for Storage on-demand malware scanning can now target individual blobs or files, containers or file shares, or objects matching a path prefix. REST API filters define the scope; without filters, the entire storage account is scanned.
What Defender admins need to know
Administrators can use targeted scans to focus malware checks on selected storage items instead of scanning the full account.

On-demand malware scanning in Microsoft Defender for Storage now supports targeted scanning of specific items. Instead of scanning an entire storage account, you can scope scans to a single blob or file, a specific container or file share, or all objects matching a path prefix.
You can use filters in the REST API request body to specify which items to scan. When no filters are provided, the scan covers the entire storage account.
