ConnectWise disables seven app identities after hackers breach Microsoft 365 tenants via Cloud Backup

Hackers accessed application identities of ConnectWise Cloud Backup (formerly SkyKick) and used them to compromise Microsoft 365 tenants. ConnectWise responded by shutting down customer access to its Cloud Backup service and disabling seven specific application identities, including ID 506e08f9-6e9a-4da4-942b-a099a03644ae, while investigations continue.

Why it matters: MSPs and enterprises relying on third‑party backup services must reassess supply‑chain security for Microsoft 365 environments.
