## Goal{% #goal %}

Detect potentially successful bruteforce attempt.

## Strategy{% #strategy %}

This rule monitors logs from OCI to detect successful bruteforce attempts. A signal is generated after 5 or more failed attempts for a specific user are followed by a successful login for the same user.

## Triage and response{% #triage-and-response %}

1. Review the logs associated with this signal. Determine if the user `{{ @usr.name }}` is expected to authenticate from the IP address `{{ @network.client.ip }}`.
1. Review audit logs for suspicious actions taken by the user after authenticating.
1. Rotate credentials for the affected account.

## Changelog{% #changelog %}
