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

1. Identify Attack Surface: Determine if the target environment is susceptible to Exfiltration Over Bluetooth by examining the target platforms (Linux, macOS, Windows).

2. Assess Existing Defenses: Review whether mitigations for T1011.001 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.
