ShoMon is a Shodan alert feeder for TheHive written in GoLang. With version 2.0, it is more powerful than ever!

Functionalities

• Can be used as Webhook OR Stream listener

  • Webhook listener opens a restful API endpoint for Shodan to send alerts. This means you need to make this endpoint available to public net
  • Stream listener connects to Shodan and fetches/parses the alert stream

• Utilizes shadowscatcher/shodan (fantastic work) for Shodan interaction.

• Console logs are in JSON format and can be ingested by any other further log management tools

• CI/CD via Github Actions ensures that a proper Release with changelogs, artifacts, images on ghcr and dockerhub will be provided

• Provides a working docker-compose file file for TheHive, dependencies

• Super fast and Super mini in size

• Complete code refactoring in v2.0 resulted in more modular, maintainable code

• Via conf file or environment variables alert specifics including tags, type, alert-template can be dynamically adjusted. See config file.

• Full banner can be included in Alert with direct link to Shodan Finding.

  

• IP is added to observables

  

Usage

• Parameters should be provided via conf.yaml or environment variables. Please see config file and docker-compose file

• After conf or environment variables are set simply issue command:

  ./shomon

Notes

• Alert reference is first 6 chars of md5(“ip:port”)
• Only 1 mod can be active at a time. Webhook and Stream listener can not be activated together.
