# T1219.003 Remote Access Hardware

> **Sub-technique of:** T1219

## High-Level Description

An adversary may use legitimate remote access hardware to establish an interactive command and control channel to target systems within networks. These services, including IP-based keyboard, video, or mouse (KVM) devices such as TinyPilot and PiKVM, are commonly used as legitimate tools and may be allowed by peripheral device policies within a target environment.

Remote access hardware may be physically installed and used post-compromise as an alternate communications channel for redundant access or as a way to establish an interactive remote session with the target system. Using hardware-based remote access tools may allow threat actors to bypass software security solutions and gain more control over the compromised device(s).

## Kill Chain Phase

- Command and Control (TA0011)

**Platforms:** Linux, macOS, Windows

## What to Check

- [ ] Identify if Remote Access Hardware technique is applicable to target environment
- [ ] Check Linux systems for indicators of Remote Access Hardware
- [ ] Check macOS systems for indicators of Remote Access Hardware
- [ ] Check Windows systems for indicators of Remote Access Hardware
- [ ] 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 Remote Access Hardware by examining the target platforms (Linux, macOS, Windows).

2. **Assess Existing Defenses**: Review whether mitigations for T1219.003 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

### M1034 Limit Hardware Installation

Block the use of IP-based KVM devices within the network if they are not required.

## Detection

### Detect Remote Access via USB Hardware (TinyPilot, PiKVM)
