🛡️ UFW AbuseIPDB Reporter

An integration tool 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 time period, the tool uses a temporary cache file to track previously reported IP addresses.

🖥️ 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.
