Instead of relying on local malware execution, they target the cloud control plane itself. They hijack high-privilege administrative identities, weaponize native cloud tools, systematically dismantle defensive barriers, and compromise entire cloud tenants from the inside out. Storm-0501, a financially motivated cybercrime group, exemplifies this tactical shift and has repeatedly demonstrated its proficiency in bridging on-premises Active Directory systems with cloud-native Microsoft Entra ID …
