T1567.001 Exfiltration to Code Repository

Sub-technique of: T1567

High-Level Description

Adversaries may exfiltrate data to a code repository rather than over their primary command and control channel. Code repositories are often accessible via an API (ex: https://api.github.com). Access to these APIs are often over HTTPS, which gives the adversary an additional level of protection.

Exfiltration to a code repository can also provide a significant amount of cover to the adversary if it is a popular service already used by hosts within the network.

Kill Chain Phase

• Exfiltration (TA0010)

Platforms: Linux, macOS, Windows, ESXi

What to Check

• Identify if Exfiltration to Code Repository technique is applicable to target environment
• Check Linux systems for indicators of Exfiltration to Code Repository
• Check macOS systems for indicators of Exfiltration to Code Repository
• Check Windows systems for indicators of Exfiltration to Code Repository
• 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 Exfiltration to Code Repository by examining the target platforms (Linux, macOS, Windows).

2. Assess Existing Defenses: Review whether mitigations for T1567.001 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.
