Sadcloud is a Terraform-based tool designed to create intentionally misconfigured AWS infrastructure for security training and testing purposes. The tool supports approximately 84 different misconfigurations across 22 AWS services, allowing security researchers and professionals to create vulnerable cloud environments in a controlled manner. It enables users to assess AWS security tools, conduct training exercises, and practice identifying cloud security vulnerabilities without affecting production systems. The tool requires users to set up a dedicated AWS account for testing purposes and includes recommendations to tear down resources when not in use to minimize costs. Sadcloud is specifically designed for educational and research purposes and should never be deployed in production environments due to its intentionally insecure configurations.
