Automatic disruption of human-operated attacks through containment of compromised user accounts
User containment is a unique and innovative defense mechanism that stops human-operated attacks in their tracks. We’ve added user containment to the automatic attack disruption capability in Microsoft Defender for Endpoint. User containment is automatically triggered by high-fidelity signals and limits attackers’ ability to move laterally within a network regardless of the compromised account’s Active Directory state or privilege level. -
Defending new vectors: Threat actors attempt SQL Server to cloud lateral movement
Microsoft security researchers recently identified an attack where attackers attempted to move laterally to a cloud environment through a SQL Server instance. The attackers initially exploited a SQL injection vulnerability in an application within the target’s environment to gain access and elevated permissions to a Microsoft SQL Server instance deployed in an Azure Virtual Machine (VM). The attackers then used the acquired elevated permission to attempt to move laterally to additional cloud resources by abusing the server’s cloud identity. -
