Huntress says a stolen Cloud Backup Microsoft 365 API secret was used in customer tenants.

ConnectWise said it found unauthorized access on October 15 to application identities in Cloud Backup, formerly SkyKick, and interrupted that service plus integrated SaaS Security and Cloud Management. As of 16:00 UTC on October 18, backups, archive access, and restores remained unavailable. ConnectWise said existing archives stayed encrypted with no evidence of unauthorized access. Huntress said a compromised Cloud Backup Microsoft 365 API secret was used to enter customer environments, including one tenant where a ConnectWise app made itself Global Administrator and added credentials.

Unconfirmed: ConnectWise has not attributed an actor and reports no evidence of archive access, while Huntress confirms credential abuse in observed tenants.
