The Hidden Risk in Virtualization: Why Hypervisors are a Ransomware Magnet
Overview
Ransomware groups are increasingly targeting hypervisors, which are the underlying technology that allows multiple virtual machines to run on a single physical server. This approach enables attackers to encrypt multiple virtual machines simultaneously with a single breach, significantly increasing the impact of their attacks. Researchers at Huntress have found that these attackers exploit gaps in visibility and security at the hypervisor layer. Organizations need to take proactive steps to secure their virtualization infrastructure against these threats. This includes implementing stricter access controls, regular monitoring, and keeping systems updated to defend against potential ransomware attacks that can disrupt operations and lead to data loss.
Key Takeaways
