2026 Critical Cloud Identity Detection: Entra Connect/AAD Connect Sync Account Credential/Config Abuse
Detects high-risk operations performed by the Entra ID/AAD Connect synchronization service account (e.g., Sync_* or ADToAADSyncServiceAccount). This account, which often holds broad directory permissions, is a prime target for attackers to gain persistence or escalate privileges within the cloud directory. The rule monitors for unauthorized sign-ins, sensitive configuration changes (such as modifications to federation trust, authentication policies, or directory synchronization settings), and password resets targeting the sync account itself.
