- Engineer — Act: If ConnectWise Cloud Backup or any of the seven disabled application identities are authorized in your Azure AD/Entra tenant, immediately revoke those OAuth consent grants and audit M365 unified audit logs for unauthorized data access using the published application identity GUIDs.
- SOC/IR — Act: Hunt M365/Entra audit logs for activity by the compromised ConnectWise application identity GUIDs (e.g., 506e08f9-6e9a-4da4-942b-a099a03644ae) — focus on anomalous OAuth token issuance, mailbox access, and SharePoint reads since the earliest possible compromise window.
- Leader — Act: Confirm whether ConnectWise Cloud Backup or related products are used by your organization; if so, request ConnectWise’s incident report, assess M365 tenant exposure, and evaluate whether any data access triggers breach-notification obligations.
