T1213.001 Confluence

Sub-technique of: T1213

High-Level Description

Adversaries may leverage Confluence repositories to mine valuable information. Often found in development environments alongside Atlassian JIRA, Confluence is generally used to store development-related documentation, however, in general may contain more diverse categories of useful information, such as:

• Policies, procedures, and standards
• Physical / logical network diagrams
• System architecture diagrams
• Technical system documentation
• Testing / development credentials (i.e., Unsecured Credentials)
• Work / project schedules
• Source code snippets
• Links to network shares and other internal resources

Kill Chain Phase

• Collection (TA0009)

Platforms: SaaS

What to Check

• Identify if Confluence technique is applicable to target environment
• Check SaaS systems for indicators of Confluence
• 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 Confluence by examining the target platforms (SaaS).

2. Assess Existing Defenses: Review whether mitigations for T1213.001 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.

Remediation Guide

M1017 User Training

Develop and publish policies that define acceptable information to be stored in Confluence repositories.

M1047 Audit

Consider periodic review of accounts and privileges for critical and sensitive Confluence repositories.

M1018 User Account Management

Enforce the principle of least-privilege. Consider implementing access control mechanisms that include both authentication and authorization.

Detection

Programmatic and Excessive Access to Confluence Documentation
