Goal

Detect when an Atlassian user is added to the organizational administrative group.

Strategy

This rule monitors Atlassian organization audit logs for when a user is added to the organizational administrative group. An attacker may try to assign a compromised identity to the organizational administrative group in order to elevate their privileges. This group contains users who manage all your sites and the organization.

Triage and response

  1. Determine if the user {{@usr.email}} intended to assign the target user to the administrative group:
    • Is there a related ticket tracking this change?
    • Is {{@usr.email}} aware of this activity?
    • Is the network metadata associated with the activity unusual for this user?
  2. If the results of the triage indicate that {{@usr.email}} 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.
