description: |
    Detects any creation or modification to a windows domain group with the name "ESX Admins".
    This could indicates a potential exploitation attempt of CVE-2024-37085, which allows an attacker to elevate their privileges to full administrative access on an domain-joined ESXi hypervisor.
    VMware ESXi hypervisors joined to an Active Directory domain consider any member of a domain group named "ESX Admins" to have full administrative access by default.
