Description
Identifies when the Microsoft 365 Global Administrator or Company Administrator role is assigned to a user or service principal. The Global Administrator role has extensive privileges across Entra ID and Microsoft 365 services, making it a high-value target for adversaries seeking persistent access. Successful assignments of this role may indicate potential privilege escalation or unauthorized access attempts, especially if performed by accounts that do not typically manage high-privilege roles.
