SpiderFoot: The Ultimate OSINT Tool

Unraveling the Web's Secrets


In the vast realm of cybersecurity, there’s a tool that has been making waves for its unparalleled ability to gather Open Source Intelligence (OSINT) – SpiderFoot. This tool is not just another name in the crowd; it’s a powerhouse that automates the collection of OSINT, making the job of cybersecurity professionals, penetration testers, and red teams a lot easier.

What is SpiderFoot?

SpiderFoot is an open-source intelligence (OSINT) automation tool. Its primary function is to automate the process of gathering intelligence about a given target, which may be an IP address, domain name, hostname, or network subnet. The tool is designed to aid security researchers and testers by providing a centralized interface to utilize a variety of online sources for information gathering.

  • Over 200 modules (see below)
  • Python 3.7+
  • YAML-configurable correlation engine with 37 pre-defined rules
  • CSV/JSON/GEXF export
  • API key export/import
  • SQLite back-end for custom querying
  • Highly configurable
  • Fully documented
  • Visualisations
  • TOR integration for dark web searching
  • Dockerfile for Docker-based deployments
  • Can call other tools like DNSTwist, Whatweb, Nmap and CMSeeK

SpiderFoot can be used offensively (e.g. in a red team exercise or penetration test) for reconnaissance of your target or defensively to gather information about what you or your organisation might have exposed over the Internet.

You can target the following entities in a SpiderFoot scan:

  • IP address
  • Domain/sub-domain name
