# T1675 ESXi Administration Command

## High-Level 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.

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`. This may enable follow-on behaviors on the guest VMs, such as File and Directory Discovery, Data from Local System, or OS Credential Dumping.

## Kill Chain Phase

- Execution (TA0002)

**Platforms:** ESXi

## What to Check

- [ ] Identify if ESXi Administration Command technique is applicable to target environment
- [ ] Check ESXi systems for indicators of ESXi Administration Command
- [ ] Verify mitigations are bypassed or absent (1 known mitigations)
- [ ] Assess detection coverage (1 detection strategies)

## How to Test

### Manual Testing

1. **Identify Attack Surface**: Determine if the target environment is susceptible to ESXi Administration Command by examining the target platforms (ESXi).

2. **Assess Existing Defenses**: Review whether mitigations for T1675 are in place. If defenses are absent or misconfigured, this technique may be exploitable.

3. **Execute Test**: Use tools and methods described in the MITRE ATT&CK page and external references below.

> **Note**: No Atomic Red Team tests available for this technique. See [Atomic Red Team GitHub](https://github.com/redcanaryco/atomic-red-team) for updates.

## Remediation Guide

### M1018 User Account Management

If not required, restrict the permissions of users to perform Guest Operations on ESXi-hosted VMs.
