Description
Adversaries may abuse ESXi administration services to execute commands on guest machines hosted within an ESXi virtual environment. Persistent background services on ESXi-hosted VMs, such as the VMware Tools Daemon Service, allow for remote management from the ESXi server. The tools daemon service runs as vmtoolsd.exe on Windows guest operating systems, vmware-tools-daemon on macOS, and vmtoolsd on Linux.(Citation: Broadcom VMware Tools Services)
Adversaries may leverage a variety of tools to execute commands on ESXi-hosted VMs – for example, by using the vSphere Web Services SDK to programmatically execute commands and scripts via APIs such as StartProgramInGuest, ListProcessesInGuest, ListFileInGuest, and InitiateFileTransferFromGuest.(Citation: Google Cloud Threat Intelligence VMWare ESXi Zero-Day 2023)(Citation: Broadcom Running Guest OS Operations) This may enable follow-on behaviors on the guest VMs, such as File and Directory Discovery, Data from Local System, or OS Credential Dumping.
How GTK Cyber trains on this
GTK Cyber's Threat Hunting with Data Science course teaches you to build machine-learning detections for techniques like this across the MITRE ATT&CK framework, including the Execution tactic this technique falls under. Practitioner-led, focused on real detections, not memorizing technique IDs.
