T1011.001 Exfiltration Over Bluetooth

Sub-technique of: T1011

High-Level Description

Adversaries may attempt to exfiltrate data over Bluetooth rather than the command and control channel. If the command and control network is a wired Internet connection, an adversary may opt to exfiltrate data using a Bluetooth communication channel.

Adversaries may choose to do this if they have sufficient access and proximity. Bluetooth connections might not be secured or defended as well as the primary Internet-connected channel because it is not routed through the same enterprise network.

Kill Chain Phase

Exfiltration (TA0010)

Platforms: Linux, macOS, Windows

What to Check

Identify if Exfiltration Over Bluetooth technique is applicable to target environment
Check Linux systems for indicators of Exfiltration Over Bluetooth
Check macOS systems for indicators of Exfiltration Over Bluetooth
Check Windows systems for indicators of Exfiltration Over Bluetooth
Verify mitigations are bypassed or absent (2 known mitigations)
Assess detection coverage (1 detection strategies)

How to Test

Manual Testing

Identify Attack Surface: Determine if the target environment is susceptible to Exfiltration Over Bluetooth by examining the target platforms (Linux, macOS, Windows).
Assess Existing Defenses: Review whether mitigations for T1011.001 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
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

M1042 Disable or Remove Feature or Program

Disable Bluetooth in local computer security settings or by group policy if it is not needed within an environment.

M1028 Operating System Configuration

Prevent the creation of new network adapters where possible.
