Azure VMs Under Siege: Cybercriminals Exploit SQL Servers as Backdoors

Innovative Cyber Threat Targets Azure Infrastructure

Subsequently, the attackers aim to access the Instant Metadata Service (IMDS) by exploiting the cloud identity of the SQL Server instance. This tactic yields a cloud identity access key, providing a gateway into the Azure VM.

While Microsoft’s researchers noted that the attackers they observed faced difficulties in completing their mission, this novel approach remains a “valid” threat and poses a significant danger to organizations worldwide. The final step in the attack involves erasing all traces of its existence.
