Hypervisor ransomware encrypts virtual machines at the ESXi/vSphere layer, taking down many VMs at once and bypassing in-guest defenses.
Hypervisor Ransomware (ESXi) Definition: Hypervisor ransomware encrypts virtual machines at the ESXi/vSphere layer, taking down many VMs at once and bypassing in-guest defenses.
Hypervisor ransomware targets virtualization platforms such as VMware ESXi/vSphere and Microsoft Hyper-V, encrypting virtual-machine disk files directly at the hypervisor layer rather than inside individual guest operating systems. Compromising a single hypervisor host can simultaneously take down dozens of VMs, maximizing impact with one action and bypassing in-guest security agents. Major ransomware families have built dedicated ESXi encryptor variants, making bare-metal hypervisors a high-value target.
Hypervisor Ransomware (ESXi) is one of the topics you'll master in the CCSP Boot Camp.
