This is detected by matching assets whose CreatedAt timestamp falls within the current query window, indicating the asset was newly added rather than updated. This helps track shadow IT, new deployments, and any unexpected expansion of the external attack surface. severity: Medium status: Available requiredDataConnectors: - connectorId: XbowSecurityConnector dataTypes: - XbowAssets_CL queryFrequency: 30m queryPeriod: 1h triggerOperator: gt triggerThreshold: 0 tactics: - Reconnaissance - Discovery relevantTechniques: - T1595 query: | XbowAssets_CL | where TimeGenerated > ago(1h) // Only match assets created within the query window (new, not updated) | where todatetime(CreatedAt) > ago(1h) | summarize arg_max(TimeGenerated, *) by AssetId | project TimeGenerated, AssetId, AssetName, StartUrl, Lifecycle, Sku, OrganizationId, CreatedAt, UpdatedAt, AssetReachableState, AssetReachableMessage eventGroupingSettings: aggregationKind: AlertPerResult alertDetailsOverride: alertDisplayNameFormat: 'XBOW New Asset: {{AssetName}}' alertDescriptionFormat: 'New asset registered in XBOW: {{AssetName}} ({{StartUrl}}).
