Automated Email Header Analysis for IP & Spoofing Detection

Webhook

Webhook Trigger

This n8n workflow is meticulously crafted for security operations, specifically designed to automate the analysis of incoming email headers. It initiates via a webhook, which serves as the entry point for raw email header data. Leveraging extensive custom code, the workflow parses these headers to extract crucial information, including sender IP addresses, the full mail server route, and various email authentication results (SPF, DKIM, DMARC). Its core objective is to identify potential email spoofing attempts by cross-referencing sender details with the actual message delivery path and authentication statuses. The sophisticated parsing and logical checks, facilitated by numerous Code nodes, enable robust detection of suspicious emails, enhancing threat intelligence and allowing security teams to quickly trace origins or feed findings into SIEM systems for further action.
