What is SpiderFoot?

SpiderFoot is an open-source OSINT automation tool that gathers intelligence about IP addresses, domains, emails, phone numbers, usernames, and more. It ships 100+ modules that feed each other in a publisher/subscriber model, runs from a web UI on port 5001 or fully from the command line, and is MIT-licensed.

Is using SpiderFoot legal?

SpiderFoot itself is a legitimate open-source security research tool. It is legal to use only on targets you own or have explicit permission to research. Scraping third-party sites without authorization, or ignoring each data source Terms of Service and rate limits, can violate computer misuse laws.

How do I install SpiderFoot on Kali Linux?

Kali ships SpiderFoot as a package: run `sudo apt install spiderfoot -y`. To get the latest modules from source, run `git clone https://github.com/smicallef/spiderfoot && cd spiderfoot && pip3 install -r requirements.txt`. Python 3.7 or newer is required.

How do I run my first SpiderFoot scan?

Start the web interface with `python3 sf.py -l 127.0.0.1:5001`, browse to http://127.0.0.1:5001, create a new scan, enter your target such as an email address or domain, and choose a scan type. From the terminal you can also run `python3 sfcli.py` and then `start example.com -u footprint -w`.

What are SpiderFoot modules and API keys?

Modules are the individual data collectors, and most of them need no API key. Keyed modules such as Shodan, HaveIBeenPwned, SecurityTrails, Censys, and AbuseIPDB are configured in the web UI Settings page, and many offer a free tier. List every module with the `modules` command inside sfcli.py.

How do I defend my own digital footprint?

Run SpiderFoot against your own email addresses and domains, then act on the findings: reduce exposure by locking down old accounts, rotate any password found in a breach and enable 2FA, close forgotten subdomains and test services, and strip metadata from photos and documents before sharing them.
