  'This query uses the Azure Defender Security Nested Recommendations data to find machines vulnerable to OMIGOD CVE-2021-38647. OMI is the Linux equivalent of Windows WMI and 
   helps users manage configurations across remote and local environments. The query aims to find machines that have this OMI vulnerability (CVE-2021-38647).
   Security Nested Recommendations data is sent to Microsoft Sentinel using the continuous export feature of Azure Defender(refrence link below).
