## What is Nimbostratus?

Nimbostratus is a collection of tools designed for fingerprinting and exploiting Amazon Web Services (AWS) cloud infrastructures. The toolkit was developed as a proof-of-concept for demonstrating security vulnerabilities in Amazon cloud environments.

The tools utilize the boto library to interact with Amazon's API, enabling security researchers and penetration testers to assess AWS infrastructure security. Nimbostratus focuses on identifying potential weaknesses and exploitation vectors within AWS cloud deployments.

The project serves as a research tool for understanding cloud security vulnerabilities and was originally created to support presentations on pivoting techniques within Amazon cloud environments. The toolkit provides functionality for reconnaissance and exploitation activities specifically targeting AWS infrastructure components.
