# T1219.002 Remote Desktop Software

> **Sub-technique of:** T1219

## High-Level Description

An adversary may use legitimate desktop support software to establish an interactive command and control channel to target systems within networks. Desktop support software provides a graphical interface for remotely controlling another computer, transmitting the display output, keyboard input, and mouse control between devices using various protocols. Desktop support software, such as `VNC`, `Team Viewer`, `AnyDesk`, `ScreenConnect`, `LogMein`, `AmmyyAdmin`, and other remote monitoring and management (RMM) tools, are commonly used as legitimate technical support software and may be allowed by application control within a target environment.

Remote access modules/features may also exist as part of otherwise existing software such as Zoom or Google Chrome’s Remote Desktop.

## Kill Chain Phase

- Command and Control (TA0011)

**Platforms:** Linux, macOS, Windows

## What to Check

- [ ] Identify if Remote Desktop Software technique is applicable to target environment
- [ ] Check Linux systems for indicators of Remote Desktop Software
- [ ] Check macOS systems for indicators of Remote Desktop Software
- [ ] Check Windows systems for indicators of Remote Desktop Software
- [ ] Verify mitigations are bypassed or absent (3 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 Desktop Software by examining the target platforms (Linux, macOS, Windows).

2. **Assess Existing Defenses**: Review whether mitigations for T1219.002 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

### M1042 Disable or Remove Feature or Program

Consider disabling unnecessary remote connection functionality, including both unapproved software installations and specific features built into supported applications.

### M1037 Filter Network Traffic

Properly configure firewalls, application firewalls, and proxies to limit outgoing traffic to sites and services used by remote access software.

### M1038 Execution Prevention

Use application control to mitigate installation and use of unapproved software that can be used for remote access.

## Detection

### Remote Desktop Software Execution and Beaconing Detection
