CNAPPgoat

CNAPPgoat is a multi-cloud, vulnerable-by-design environment deployment tool – specifically engineered to facilitate practice arenas for defenders and pentesters. Its main function is to deploy intentionally vulnerable environments across multiple cloud service providers, to help you sharpen your skills in exploiting, detecting, and preventing such vulnerabilities.

Warning: CNAPPgoat deploys vulnerable environments. Only use it within safe, controlled sandboxes.

CNAPPgoat operates as a Command Line Interface (CLI) tool, capable of deploying vulnerable environments to a multitude of cloud service providers. Built with Go and utilizing Pulumi and the Pulumi automation API, it ensures seamless environment deployment. One of its unique features is its modular design, which allows for effortless extension to support an array of cloud service providers and new vulnerable environments. As of now, CNAPPgoat supports AWS, Azure, and GCP.

• Pulumi
• Cloud SDKs for the cloud provider you are using:
  • AWS CLI
  • Azure CLI
  • Google Cloud SDK

Pulumi dependencies and plugins will install in an on-demand basis according to each scenario's requirements when you provision your first environment. This means the first time provisioning might take a little longer than subsequent ones.

CNAPPgoat can be easily installed for macOS users using the Homebrew package manager.

brew tap ermetic-research/cnappgoat
brew install cnappgoat

1. Download the latest release from here.

   tar -xvf cnappgoat-<version>.tar.gz
   cd cnappgoat-<version>

2. (Optional) If you'd like to add the extracted binary to your system's PATH (you don't have to, you can just run it from the local directory as ./cnappgoat):

Option A: Move to a directory in your PATH (e.g., /usr/local/bin for macOS and Linux)

mv cnappgoat /usr/local/bin/

Option B: Add the directory containing the binary to your PATH

For bash:

echo 'export PATH=$PATH:<path_to_directory_containing_cnappgoat>' >> ~/.bashrc
source ~/.bashrc

For zsh:

echo 'export PATH=$PATH:<path_to_directory_containing_cnappgoat>' >> ~/.zshrc
source ~/.zshrc

Replace <path_to_directory_containing_cnappgoat> with the absolute path to the directory where cnappgoat binary resides.

NAME:
   cnappgoat - A multicloud open-source tool for deploying vulnerable-by-design cloud resources

USAGE:
   cnappgoat [global options] command [command options] [arguments...]

VERSION:
   0.1.0-beta, date: 2023-08-02T13:02:46Z, commit: 6bef61857d9f3cf88215269df8976f96317711dc


COMMANDS:
   clean      clean and remove all created resources and delete all scenarios and any related files
   describe   describe a scenario
   destroy    Destroy CNAPPgoat module scenarios
   list       List CNAPPgoat module scenarios
   provision  Provision CNAPPgoat module scenarios
   help, h    Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --debug        Enable debug mode (default: false)
   --help, -h     show help
   --version, -v  print the version

You may use multiple arguments separated by spaces. For example:

cnappgoat provision <scenario-1> <scenario-2> <scenario-N>

• --module - Filters scenarios by module (e.g. CSPM, CIEM, CWPP, DSPM, KSPM etc.)
• --platform - Filters scenarios by platform (e.g. AWS, Azure, GCP)
• --force - Enables force mode (unlock locked stacks with pulumi cancel)
• --debug - Enables debug logging.

These flags are command flags and should be placed after the command. For example:

cnappgoat provision --module CSPM --platform AWS

This command will provision all AWS CSPM scenarios.

CNAPPgoat downloads scenarios from the cnappgoat-scenarios repository at its first run of every day, these scenarios are automatically downloaded when you run CNAPPgoat and are stored in the ~/.cnappgoat/scenarios directory.

Before you can use CNAPPgoat, you need to set up your cloud credentials for AWS, Azure, and GCP. CNAPPgoat uses the default credentials for each provider. Follow the steps below to set up your credentials:

1. Install the AWS CLI by following the instructions here.

2. Configure your AWS credentials by running:

   aws configure

   You'll be prompted to enter your Access Key ID, Secret Access Key, and default region name.

1. Install the Azure CLI by following the instructions here.

2. Log in to your Azure account by running:

   az login

   This will open a new browser window for you to log in. After logging in, your credentials will be stored for future use.

1. Install the Google Cloud SDK by following the instructions here.

2. Authenticate with Google Cloud by running:

   gcloud auth login

   This will open a new browser window for you to log in. After logging in, your credentials will be stored for future use.

By setting these credentials, you will be able to deploy scenarios on AWS, Azure, and GCP using CNAPPgoat. If you're planning on using CNAPPgoat with a different provider, make sure to configure the credentials accordingly.

CNAPPgoat provisions a breadth of vulnerable scenarios on multiple clouds to test detection and prevention capabilities. There are other great projects out there for vulnerable cloud environments that are focused on different areas, such as exploitation, detection, CTF (capture the flag) scenarios, etc. We were inspired by these tools and projects, and we recommend checking them out:

• Stratus Red Team by DataDog: a tool that allows users to emulate offensive attack techniques in a granular and self-contained manner
• Cloud Goat by Rhino Security Labs: a "Vulnerable by Design" AWS deployment tool. It allows you to hone your cloud cybersecurity skills by creating and completing several " capture-the-flag" style scenarios
• Kubernetes Goat by Madhu Akula: an intentionally vulnerable cluster environment to learn and practice Kubernetes security
• TerraGoat by Bridgecrew: a "Vulnerable by Design" Terraform repository
• CloudFoxable by BishopFox: a gamified cloud hacking sandbox

More challenges and tools can be found in the Awesome Cloud Security Challeges repo by Mike Privitte, our list focused specifically on vulnerable-by-design cloud environments that are deployed by users in their own sandbox.
