fail2ban Reporter

Monitor fail2ban bans and auto-report attackers to AbuseIPDB.

Setup

1. Get a free AbuseIPDB API key at https://www.abuseipdb.com/account/api
2. Store it: pass insert abuseipdb/api-key
3. Install the monitor: bash {baseDir}/scripts/install.sh

Manual Usage

Report all currently banned IPs

bash {baseDir}/scripts/report-banned.sh

Check a specific IP

bash {baseDir}/scripts/check-ip.sh <ip>

Show ban stats

bash {baseDir}/scripts/stats.sh

Auto-Reporting

The install script sets up a fail2ban action that auto-reports new bans.

bash {baseDir}/scripts/install.sh    # install auto-reporting
bash {baseDir}/scripts/uninstall.sh  # remove auto-reporting

Heartbeat Integration

Add to HEARTBEAT.md to check for new bans periodically:

- [ ] Check fail2ban stats and report any unreported IPs to AbuseIPDB

Workflow

1. fail2ban bans an IP → action triggers report-single.sh
2. Script reports to AbuseIPDB with SSH brute-force category
3. Sends Telegram notification (if configured)
4. Logs report to /var/log/abuseipdb-reports.log
