ThreatBite - reputation checking tool

GithubActions Go Report Card Version

About

ThreatBite is a global reputation system used internally by Optimatiq. It analyses incoming internet users and sends back a standardized score representing their trustworthiness. The program uses independent databases that collect up-to-date information about bad internet actors. Because it is an API service, it works in real-time, allowing you to act fast and block or keep an eye on suspicious user behavior.

Configuration

Configuration is done via env variables or config.env file. All parameters are optional:

  • PORT - API listening port default 8080
  • DEBUG - values: false, true, 1, 0 or empty
  • AUTO_TLS - values: false, true, 1, 0 or empty, automatic access to certificates from Let's Encrypt

License keys for these external services will improve the quality of the results. It is highly recommended to set them.

Correct communication with the MTA server requires the following settings. Otherwise, the server may close the connection with the error:

  • SMTP_HELLO - the domain name or IP address of the SMTP client that will be provided as an argument to the HELO command
  • SMTP_FROM - MAIL FROM value passed to the SMTP server

IP/CIDR lists contain information about addresses used as proxy/VPN or other malicious activity. You can provide one or many sources separated by whitespace. The format of the data is straightforward, and each line contains one IP or CIDR addresses. Threadbite open-source version provides public sources that are limited in scope and might be outdated with no SLA. If you interested in curated and more accurate lists with SLA, please contact us at [email protected]
