Who is this workflow for? Enhance your cybersecurity operations with this n8n workflow, designed to seamlessly integrate URL and IP lookups using GreyNoise and VirusTotal. Automate threat intelligence gathering to quickly assess and respond to potential security threats..

What does this workflow do?

  • Trigger Initiation: The workflow begins with either a form submission or a webhook trigger, allowing users to input a URL or IP address for analysis.
  • Input Validation: Determines whether the input is a URL or an IP address. If a URL is provided, it performs a DNS lookup using Google Public DNS to extract the associated IP address.
  • Greynoise IP Lookup:
  • RIOT IP Lookup: Assesses the reputation of the IP and checks for association with known benign services.
  • IP Context: Evaluates the IP for potential threats based on GreyNoise’s threat intelligence.
  • Merge GreyNoise Results: Combines data from both Greynoise services to generate a comprehensive IP analysis, including classification, location, tags, category, and trust level.
  • VirusTotal Scan: Initiates a scan of the URL/IP with VirusTotal to identify malicious indicators. Implements a 5-second wait to ensure processing.
  • Poll Scan Results: Continuously checks the status of the VirusTotal scan until the analysis is complete.
  • Summarize Analysis: Consolidates results from GreyNoise and VirusTotal, detailing security vendor findings, blocklist statuses, OpenPhish analysis, and the original URL/IP.
  • Notification: Sends the summarized threat intelligence to the user via Gmail or Slack, ensuring timely awareness and response.

🤖 Why Use This Automation Workflow?

  • Comprehensive Analysis: Leverages multiple threat intelligence sources to provide a detailed assessment.
  • Automation: Streamlines the threat detection process, reducing manual effort and response time.
  • Integration Flexibility: Connects with various tools like Gmail and Slack for efficient reporting and notifications.

👨‍💻 Who is This Workflow For?

This workflow is ideal for cybersecurity professionals, IT administrators, and security operations centers (SOCs) seeking to automate and enhance their threat intelligence capabilities without extensive manual intervention.

🎯 Use Cases

  1. Incident Response: Quickly assess the threat level of suspicious URLs or IP addresses during security incidents.
  2. Threat Hunting: Continuously monitor and analyze network traffic for potential malicious activities.
  3. Vulnerability Management: Integrate with vulnerability scanners to validate the security status of assets based on real-time threat intelligence.

TL;DR

This n8n workflow automates the process of analyzing URLs and IP addresses using GreyNoise and VirusTotal, providing comprehensive threat intelligence. By integrating seamlessly with notification platforms like Gmail and Slack, it ensures that relevant stakeholders receive timely and actionable security insights.
