Goal

Detect when a Slack users role has been changed to an administrator or owner.

Strategy

This rule monitors Slack audit logs for when a Slack user’s role has been changed to an administrator or owner. Roles determine what people can see and do in Slack. There are administrative roles that are designed for people who are responsible for managing accounts and settings in Slack.

Triage and response

  1. Determine if the change taken by {{@usr.email}} is authorized.
  2. If the change was not authorized or was unexpected, begin your organization’s incident response process and investigate.
