Virtual Machine Discovery

An adversary may attempt to enumerate running virtual machines (VMs) after gaining access to a host or hypervisor. For example, adversaries may enumerate a list of VMs on an ESXi hypervisor using a Hypervisor CLI such as esxcli or vim-cmd (e.g. esxcli vm process list or vim-cmd vmsvc/getallvms).^[1][2] Adversaries may also directly leverage a graphical user interface, such as VMware vCenter, in order to view virtual machines on a host.

Adversaries may use the information from Virtual Machine Discovery during discovery to shape follow-on behaviors. Subsequently discovered VMs may be leveraged for follow-on activities such as Service Stop or Data Encrypted for Impact.^[1]
