🛡️ UFW AbuseIPDB Reporter

A utility designed to analyze UFW logs and report IP addresses blocked by the firewall to the AbuseIPDB database.
To prevent excessive reporting of the same IP address within a short period, the tool uses a temporary cache file to track previously reported IP addresses.

4. Linux

✅ Features

1. Easy Configuration – The config.js file allows for quick and simple customization.
2. Simple Installer – Enables fast and seamless integration deployment.
3. Bulk Reporting Support – If the script encounters a rate limit, it will start buffering collected IPs and send a bulk report.
4. Self-IP Protection (IPv4 & IPv6) – The script will never report IP addresses belonging to you or your server, even if you're using a dynamic IP address.
5. Local IP Filtering (beta) – Local IP addresses will never be reported.
6. Discord Webhooks Integration:
   • Critical notifications
   • Script error alerts
   • Daily summaries of reported IPs
7. Automatic Updates – The script regularly fetches and applies the latest updates. You can disable this if you prefer.

🖥️ Usage

After a successful installation, the script will run continuously in the background, monitoring UFW logs and automatically reporting IP addresses.

Servers are constantly scanned by bots, usually looking for security vulnerabilities and similar weaknesses. So don't be surprised if the number of reports sent to AbuseIPDB exceeds a thousand the next day.
