Keypoints
- AWS SNS is used to send messages between distributed systems but can pose risks if misconfigured.
- The scenario involves using CloudGoat and Pacu tools to exploit SNS vulnerabilities to access secrets.
- An attacker can subscribe to SNS topics, confirm subscriptions, and extract API Gateway keys.
- Enumerating API Gateway resources allows attackers to craft URLs for data exfiltration.
- Proper access control and configuration are essential to prevent privilege escalation via SNS.
