In practice

Written by AI from this repository’s README · high confidence

Recon means querying dozens of data sources by hand and stitching the results together manually.

Use it when

Use it for attack surface mapping or red team recon against a domain, IP range, ASN, email or username.

Not the right pick when

The open source version is single user and single target per scan, with monitoring and REST API reserved for the paid HX product.

SpiderFoot is an open source intelligence (OSINT) automation tool. It integrates with just about every data source available and utilises a range of methods for data analysis, making that data easy to navigate.

SpiderFoot has an embedded web-server for providing a clean and intuitive web-based interface but can also be used completely via the command-line. It's written in Python 3 and MIT-licensed.

USES

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
  • Hostname
  • Network subnet (CIDR)
  • ASN
  • E-mail address
  • Phone number
  • Username
  • Person's name
  • Bitcoin address

SpiderFoot's 200+ modules feed each other in a publisher/subscriber model to ensure maximum data extraction to do things like:

INSTALLING & RUNNING

To install and run SpiderFoot, you need at least Python 3.7 and a number of Python libraries which you can install with pip. We recommend you install a packaged release since master will often have bleeding edge features and modules that aren't fully tested.

Stable build (packaged release):

 wget https://github.com/smicallef/spiderfoot/archive/v4.0.tar.gz
 tar zxvf v4.0.tar.gz
 cd spiderfoot-4.0
 pip3 install -r requirements.txt
 python3 ./sf.py -l 127.0.0.1:5001
Development build (cloning git master branch):

 git clone https://github.com/smicallef/spiderfoot.git
 cd spiderfoot
 pip3 install -r requirements.txt
 python3 ./sf.py -l 127.0.0.1:5001

WRITING CORRELATION RULES

We have a comprehensive write-up and reference of the correlation rule-set introduced in SpiderFoot 4.0 here.

Also take a look at the template.yaml file for a walk through. The existing 37 rules are also quite readable and good as starting points for additional rules.
