Summary

Hide ▲

Storm-0501 is running an opportunistic cloud extortion campaign that has affected multiple organizations across sectors, widening risk for hybrid-cloud tenants. The group uses stolen credentials, DCSync, and privilege escalation to move from on-premises systems into cloud identities and resources. It then exfiltrates data, destroys backups, and mass-deletes Azure resources to pressure victims into paying. The latest wave shows the operation adapting beyond a single sector while preserving a repeatable cloud-ransomware playbook.
