The SCKit worm exploited cloud-hosted ScreenConnect panels to deploy rogue clients and a toolkit across hundreds of endpoints in multiple organizations. It spreads by stealing session cookies to move from infected endpoints to technician workstations and then laterally to other endpoints. The toolkit uses encrypted payloads keyed by system UUIDs to install persistence mechanisms and attempt console takeover. Although endpoint infections were successful, technician workstation compromises failed in observed cases. ConnectWise disabled some third-party extensions as a precaution but has not identified the initial access vector.
