Id	1d767977-460a-29c3-06f7-799a91a80daf
Rulename	UniFi Site Manager: Firmware drift hotspots
Description	Devices behind on firmware updates - ranked by product line and model. Identifies models where firmware drift is concentrated, indicating either a vendor-side delay or operational neglect. Each unpatched device is a CVE attack surface.
Tactics	Reconnaissance
Techniques	T1595
Required data connectors	UniFiSiteManagerConnectorDefinition
Kind	HuntingQuery
Source Uri	https://github.com/Azure/Azure-Sentinel/blob/master/Solutions/UniFi Site Manager (CCF)/Hunting Queries/UniFiCloudFirmwareDriftHotspots.yaml
Version	1.0.0
Arm template	1d767977-460a-29c3-06f7-799a91a80daf.json
