Hello,
In this PR I've added the SID S-1-5-32-551 aka Backup Operators to High value by default.
https://docs.microsoft.com/en-us/windows/security/identity-protection/access-control/security-identifiers
Members of this group can dump remotely the sam/security/system files of the domain controller and therefore dcsync the domain, become domain admins etc. If you compromise one member of this group, you are one step closer to become DA.
You can find more information and demo on this poc for Windows and for Linux :
