 There are no known ways to abuse membership in this group to compromise Tier Zero.

Additionally, control over the group allows one to impact the operability of Tier Zero by removing domain controllers from the group, which breaks AD replication.

 Enterprise Admins;AD group;Active Directory;SID: S-1-5-21-<root domain>-519;"The Enterprise Admins group exists only in the root domain of an Active Directory forest of domains. The group is a Universal group if the domain is in native mode. The group is a Global group if the domain is in mixed mode. Members of this group are authorized to make forest-wide changes in Active Directory, like adding child domains.
 
 By default, the only member of the group is the Administrator account for the forest root domain. This group is automatically added to the Administrators group in every domain in the forest, and it provides complete access to configuring all domain controllers. Members in this group can modify the membership of all administrative groups. Members of the default service administrator groups in the root domain can modify Enterprise Admins membership. This group is considered a service administrator account.
