Goal

Detect when a Confluence space export occurs.

Strategy

This rule monitors Confluence audit logs for when a space export occurs. Space admins can export a space (or a group of individually selected pages in a space) to PDF, CSV, HTML, or XML.

Due to the sensitive nature of data documented on confluence, an attacker may export this data in order to mine for valuable information.

Triage and response

  1. Determine if the user {{@usr.name}} intended make to enable the public link:
    • Is {{@usr.name}} aware of this activity?
  2. If the results of the triage indicate that {{@usr.name}} was not aware of this activity or it did not originate from a known network, begin your company’s incident response process, and start an investigation.
