Overview

Goal

Detect when an attacker is trying to evade defenses by deleting or disabling EventBridge rules.

Strategy

This rule lets you monitor these CloudTrail API calls to detect if an attacker is modifying or disabling EventBridge rules:

Triage & Response

  1. Determine which user in your organization owns the API key that made this API call.
  2. Contact the user to see if they intended to make this API call.
  3. If the user did not make the API call:
    • Rotate the credentials.
    • Investigate if the same credentials made other unauthorized API calls.
