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 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)
