Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence.

To learn more about this, visit our documentation.

It relies heavily on its plugin system to provide basic scanning capabilities. All publicly available to this plugins are hosted in a separate google/tsunami-security-scanner-plugins repository.

Current Status

  • Currently it is in ‘pre-alpha’ release for developer preview.
  • The project is currently under active development. Do expect major API changes in the future.

Quick Start

To quickly get started with its scans,

  • install the following required dependencies: nmap >= 7.80 ncrack >= 0.7
  • start a vulnerable application that can be identified by it, e.g. an unauthenticated Jupyter Notebook server. The easiest way is to use a docker image: docker run –name unauthenticated-jupyter-notebook -p 8888:8888 -d jupyter/base-notebook start-notebook.sh –NotebookApp.token=”
  • execute the following command: bash -c "$(curl -sfL https://raw.githubusercontent.com/google/tsunami-security-scanner/master/quick_start.sh)"

The quick_start.sh script performs the following tasks:

  • Clone the google/tsunami-security-scanner and google/tsunami-security-scanner-plugins repos into $HOME/tsunami/repos directory.
  • Compile all Google Tsunami plugins and move all plugin jar files into $HOME/tsunami/plugins directory.
  • Compile the it scanner Fat Jar file and move it into $HOME/tsunami directory.
  • Move the tsunami.yaml example config into $HOME/tsunami directory.
  • Print example for this tool to command for scanning using the previously generated artifacts.
