Goal

Detect when a user has marked a Duo push as fraudulent.

Strategy

This rule monitors Cisco Duo logs for when a user marks a Duo push as fraudulent. If a user suspects that a Duo push is suspicious, such as an unusual location or application name, they will mark the push as fraudulent.

Triage and Response

  1. Contact the user {{@usr.email}} to confirm why they thought the push was suspicious.
  2. Investigate the push event, focusing on the IP address {{@access_device.ip}} and application {{@application.name}}.
  3. If the event is deemed malicious, begin your organization’s incident response process to contain the affected account or device.
