AWS EventBridge is a serverless event bus service that enables powerful integrations across multiple AWS accounts. The attacks: 1. Persistent beaconing 2. Command and control 3. Reconnaissance 4. Data smuggling 5. Account hopping 6. API borrowing The post provides code examples for each attack and recommends multi-layered security controls, including Service Control Policies, IAM permissions, EventBridge resource policies, VPC endpoints with restrictive policies, and event content validation, along with detection strategies using CloudWatch, CloudTrail, and behavioral analytics. developer.squareup.com/blog/… #cybersecurity
