Automated Breach Alert System for HaveIBeenPwned

This n8n workflow automatically checks for new data breaches reported on haveibeenpwned.com every 15 minutes and sends alerts for any new breaches. It starts with a schedule trigger, which runs the process periodically. The workflow then makes an HTTP request to fetch the latest breach data. It reads the last breach recorded from a cache file and compares it with the new data. If a new breach is detected, it updates the cache and triggers an alert. Previously seen breaches are identified to avoid duplicate notifications. The workflow also includes sticky notes for documentation and a cleanup step that resets the cache, ensuring fresh checks on subsequent runs. This automation is useful for security teams or individuals monitoring data breaches to stay informed of new vulnerabilities promptly.
