New MsDS-DelegatedManagedServiceAccount (DMSA) Object Created — Detection Rule
Detects the creation of new msDS-DelegatedManagedServiceAccount objects, which could indicate potential abuse of privilege escalation vulnerabilities in Windows Server 2025. The msDS-DelegatedManagedServiceAccount (DMSA) is a new object class introduced in Windows Server 2025 that allows administrators to delegate the management of service accounts to other users or groups. Attackers may exploit this feature to create unauthorized service accounts with elevated privileges, leading to privilege escalation within the Active Directory environment. It is highly suspicious if an msDS-DelegatedManagedServiceAccount object is created without proper authorization or in an unexpected context, such as by a non-administrative user or outside of normal administrative workflows. So, it's a good idea to look out for accounts that are not typically responsible for service account creation to detect potential abuse of this feature.
