Analyze_email_headers_for_IPs_and_spoofing__3

This workflow is ideal for:

• Email Administrators: Those managing email systems who need to ensure the authenticity of incoming emails and protect against phishing and spoofing attacks.
• Security Analysts: Professionals focused on cybersecurity who require detailed insights into the reputation of IP addresses associated with email communications.
• Developers: Individuals looking to integrate email header analysis into applications or services to enhance security features.
• Businesses: Organizations that rely on email for communication and want to safeguard their reputation by filtering fraudulent emails.

This workflow addresses the critical issue of email spoofing and phishing attacks by analyzing email headers. It extracts IP addresses from headers and assesses their reputation using external APIs, thus helping to identify potentially harmful emails. Additionally, it evaluates the authentication results (SPF, DKIM, DMARC) to ensure that emails are legitimate and meet security standards, thereby enhancing overall email security.

1. Receive Headers: The workflow begins by receiving email headers via a webhook.
2. Extract Email Header: The headers are extracted from the incoming request for further analysis.
3. Explode Email Header: The header string is split into individual components for detailed examination.
4. Check for Received Headers: It checks if the email contains received headers to determine the next steps.
5. Extract IPs: If received headers are present, the workflow extracts IP addresses using regex patterns.
6. Analyze IPs: The extracted IPs are sent to the IP Quality Score API for fraud scoring and reputation assessment.
7. Geolocation Data: The IP-API provides geolocation data for the analyzed IPs.
8. Collect Data: Relevant information such as fraud scores, recent abuse, and ISP details are collected for each IP.
9. Authentication Results: The workflow checks for authentication-results headers to evaluate SPF, DKIM, and DMARC status.
10. Aggregate Results: The data from both paths (IP analysis and authentication results) is merged to create a comprehensive report.
11. Respond to Webhook: Finally, the results are sent back to the webhook, providing a detailed analysis of email security and IP reputation.
