SpiderFoot – An Automated OSINT Framework in Kali Linux

The SpiderFoot Kali Linux install takes under five minutes and gives you a full open-source intelligence (OSINT) automation framework that ships ready to run inside Kali. SpiderFoot is a free, open-source reconnaissance tool written in Python 3 that collects data from over 200 public sources and connects the results into a single visual map. On Kali Linux, the tool sits among the standard security packages, so you set it up either through the packaged release, the development build from the Git master branch, or a Kali metapackage.

SpiderFoot in Kali Linux serves three core jobs: passive footprinting, active reconnaissance, and breach discovery against a domain, IP address, email address, or person’s name. The framework benefits red teamers running pre-engagement recon, blue teams checking their own exposed data, and investigators tracing digital identities. Each task runs through modules, and each module targets one data source or technique.

The SpiderFoot package on Kali ships two main components: the spiderfoot web server and the spiderfoot-cli command-line client. This guide walks through the features, the uses, every installation method, real scan examples, the module system, correlation rules, and where to find documentation and community support. By the end you will have SpiderFoot installed on Kali Linux, the web interface running, and a first scan completed against a live target.

Features

SpiderFoot carries 6 features that make it a core OSINT tool in Kali Linux.

• Automated collection gathers intelligence from 200+ public and commercial data sources without manual lookups.
• Dual interfaces give you a browser-based web GUI and a spiderfoot-cli terminal client for scripted scans.
• Modular design runs over 200 modules, and you enable or disable each one per scan.
• Active and passive modes let you choose stealthy passive collection or direct active probing of a target.
• Visual reporting maps relationships between domains, IPs, emails, and hosts through interactive graphs.
• Open source license keeps the framework free under the MIT License, so you read, edit, and extend the source.

SpiderFoot was created by Steve Micallef, and the project accepts contributions from developers worldwide through GitHub. The codebase is mostly Python, which means it runs the same way across Kali Linux, Debian, and other distributions.

The web GUI and the spiderfoot-cli client cover two different work styles. The GUI suits visual review, where you watch a scan progress and click through the result graph. The CLI suits automation, where you start scans from a script and pull results into a pipeline. Both connect to the same scan engine, so a scan you start in the terminal shows up in the web interface as well.

Uses

SpiderFoot in Kali Linux covers 5 primary uses.

• Penetration testing automates pre-engagement footprinting, so testers map a target’s external surface before active exploitation.
• Red team operations speed up reconnaissance by pulling exposed data, weak configurations, and attack vectors from hundreds of sources.
• Breach monitoring checks email addresses and domains against breach databases to confirm leaked credentials.
• Defensive security reveals what information about your own infrastructure sits exposed in public, including DNS records and employee emails.
• Incident response correlates indicators of compromise such as malicious IPs, domains, and hashes during an investigation.

The tool works against 6 target types: domain names, IP addresses, hostnames, subnets, autonomous system numbers (ASN), and email addresses. You point SpiderFoot at any one of these, select your modules, and the framework handles the rest.

Installation

Kali Linux supports 3 SpiderFoot installation methods: the stable packaged release through apt, the development build cloned from the Git master branch, and Kali metapackages. Pick the method that matches your need. The packaged release suits most users. The Git build gives you the newest modules. Metapackages install SpiderFoot alongside a wider toolset.

Before any method, update your package sources.

sudo apt update

Stable Build (Packaged Release)

This SpiderFoot Kali Linux tutorial starts with the stable build, since it suits most users. To install the stable SpiderFoot build on Kali Linux, run the apt command.

sudo apt install spiderfoot

This command pulls the packaged release from the Kali repository and installs the spiderfoot server, the spiderfoot-cli client, and all Python dependencies. The stable build is tested against the current Kali release, so it gives you the most reliable setup. This SpiderFoot install kali method needs no manual dependency work.

Launch the web interface after installation.

spiderfoot -l 127.0.0.1:5001

Open a browser and go to http://127.0.0.1:5001. The SpiderFoot GUI on Kali loads in the browser, and you start scans from there. The web GUI is the part most users mean when they search for the SpiderFoot Kali tool, since it turns a command-line framework into a point-and-click interface.

Development Build (Cloning Git Master Branch)

The development build gives you the latest SpiderFoot code straight from the GitHub master branch. Use this method when you want modules or fixes that have not reached the packaged release yet. The SpiderFoot GitHub Kali Linux source lives in the repository smicallef/spiderfoot.

Clone the SpiderFoot GitHub repository on Kali Linux.

git clone https://github.com/smicallef/spiderfoot.git

Move into the project directory.

cd spiderfoot

Install the Python dependencies.

pip3 install -r requirements.txt

On recent Kali releases, pip may block a system-wide install with an “externally managed environment” message. Create a virtual environment, if that message appears.

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Start the SpiderFoot web server.

python3 sf.py -l 127.0.0.1:5001

The development build now runs from your cloned folder, and you reach the GUI at http://127.0.0.1:5001.

Metapackages

Kali Linux metapackages bundle groups of tools into a single install. SpiderFoot ships inside the information-gathering and OSINT metapackages, so installing one of these brings SpiderFoot plus related recon tools such as recon-ng and theHarvester.

Install the relevant metapackage.

sudo apt install kali-tools-information-gathering

This method suits a fresh Kali setup where you want the full reconnaissance toolset in one step rather than installing each tool by hand.

Packages & Binaries

The SpiderFoot package on Kali Linux installs 2 binaries: spiderfoot and spiderfoot-cli. Each binary handles a separate part of the workflow.

spiderfoot

The spiderfoot binary runs the web server and the scan engine. Start it with the listen flag to bind the web interface to an address and port.

spiderfoot -l 127.0.0.1:5001

The -l flag sets the listen address. Use 127.0.0.1:5001 for local-only access. Bind to 0.0.0.0:5001 to reach the interface from another machine on your network, and protect that setup with authentication.

spiderfoot-cli

The spiderfoot-cli binary connects to the running SpiderFoot server from the terminal, so you start, monitor, and pull scan results without the browser. This client suits scripted workflows and remote sessions.

spiderfoot-cli -s http://127.0.0.1:5001

The -s flag points the client at the server URL. Once connected, you run scan commands directly from the command line.

Examples

SpiderFoot Kali How to Use

To use SpiderFoot in Kali Linux, start the server, open the web GUI, set a target, pick modules, and run the scan. A SpiderFoot scan on Kali Linux runs in 4 steps: define the target, select modules, run the scan, and review results. These examples use the web GUI and the CLI.

Example 1 — Passive domain scan. Open the web interface, enter a domain such as example.com as the target, choose the passive scan setting, and start. SpiderFoot queries WHOIS, DNS records, and breach databases without touching the target directly.

Example 2 — CLI scan against an IP. Connect with spiderfoot-cli, then start a scan against an IP address.

spiderfoot-cli -s http://127.0.0.1:5001
sf> scans -t 8.8.8.8 -m sfp_dnsresolve,sfp_shodan

The -t flag sets the target, and -m lists the modules to run.

Example 3 — Email breach check. Set an email address as the target and enable the Have I Been Pwned module. SpiderFoot reports whether that address appears in known breaches.

Example 4 — Headless scan for automation. Run SpiderFoot in headless mode from a script, collect the scan ID, and export the results as CSV or JSON for a report.

Each scan writes results to the spiderfoot.db database file, so you reopen and re-examine past scans at any time.

Example 5 — Custom scan profile. Save a fixed set of modules as a scan profile in the web interface, then reuse that profile across many targets. A profile that pairs DNS, WHOIS, and SSL modules gives a fast infrastructure overview on every new domain.

Example 6 — Data export for reporting. After a scan finishes, open the scan results and export the data as CSV, JSON, or GEXF. The CSV file suits spreadsheets, the JSON file suits scripts, and the GEXF file feeds graph tools such as Gephi or Neo4j.

Troubleshooting Common Install Issues

SpiderFoot on Kali Linux can hit 4 common setup problems, and each has a direct fix.

• Failed to connect means the web server is not running on the address you opened. Start the server with spiderfoot -l 127.0.0.1:5001, then reload the browser.
• Externally managed environment appears when pip blocks a system-wide install. Create a virtual environment with python3 -m venv venv, activate it, then install the requirements inside it.
• No results returned points to a module set that is too narrow or missing API keys. Add more modules and configure the keys for sources such as Shodan and VirusTotal.
• Port already in use means another process holds port 5001. Launch SpiderFoot on a free port, for example spiderfoot -l 127.0.0.1:5002.

API Key Configuration

Some SpiderFoot modules need an API key from the data provider before they return results. Configure these keys once, and SpiderFoot reuses them on every scan. Open the web interface, go to Settings, find the module, and paste the key into its field. Modules that commonly need keys include Shodan, VirusTotal, Have I Been Pwned, and Censys. Free modules such as DNS resolve and WHOIS lookup run without any key.

Running SpiderFoot with Docker on Kali

Docker keeps SpiderFoot and its dependencies inside one container, which avoids dependency conflicts on Kali Linux. Pull and run the official image in 2 commands.

docker pull smicallef/spiderfoot
docker run -p 5001:5001 smicallef/spiderfoot

The -p flag maps the container port to your host, so you reach the web interface at http://127.0.0.1:5001. This method suits users who want a clean setup that they remove in one step.

SpiderFoot Kali Linux Commands

The core SpiderFoot Kali Linux commands cover 4 actions: starting the server, connecting the CLI, running a scan, and stopping the server. Start the server with spiderfoot -l 127.0.0.1:5001. Connect the client with spiderfoot-cli -s http://127.0.0.1:5001. Run a scan from the CLI with the scans -t <target> -m <modules> syntax. Stop the server with Ctrl + C in the terminal that runs it. These commands give you full control over a SpiderFoot scan without the browser.

Modules / Integrations

SpiderFoot runs over 200 modules, and each module connects to one data source or performs one technique. The module system is the core of how the framework gathers intelligence on Kali Linux.

6 module groups cover the most common OSINT needs.

• WHOIS and DNS modules retrieve domain registration details, name servers, and DNS records.
• Shodan and Censys modules scan internet-facing devices for open ports, services, and fingerprints.
• Have I Been Pwned module checks emails and domains against breach records.
• VirusTotal module returns file reputation scores and URL scan data.
• PassiveTotal module delivers passive DNS and historical infrastructure data.
• SSL and geolocation modules collect certificate details and map IP locations.

Some modules need an API key from the source provider. You add these keys in the module settings inside the web interface, and SpiderFoot then uses them on every scan. Modules without a key requirement run straight away.

SpiderFoot integrates with external tools as well. The framework exports data for use in Maltego, feeds results into a Neo4j graph database, and connects to SIEM platforms through its export formats.

Writing Correlation Rules

SpiderFoot correlation rules turn raw scan data into prioritized findings. A correlation rule scans the collected results and flags patterns that matter, such as an exposed credential tied to a live host. The framework ships with a set of built-in rules, and you write your own.

Correlation rules use YAML format. Each rule defines what data types to match, what conditions trigger the rule, and how to label the result. You place custom rule files in the correlations directory inside the SpiderFoot folder, and the engine applies them on the next scan.

Writing a custom rule suits teams that hunt for a specific risk across many scans. A rule that flags every email address found in a breach, for example, saves you from reading through full result sets by hand.

A correlation rule holds 3 main parts: the id and meta block that names the rule, the collections block that defines which data types to match, and the headline that labels the flagged result. You write the rule in a .yaml file, drop it in the correlations folder, and the engine loads it on the next scan. The framework then groups matching findings under your headline, so the highest-risk results sit at the top of the scan report.

Documentation

The official SpiderFoot documentation lives on the GitHub repository at smicallef/spiderfoot and in the project wiki. The documentation covers installation, module configuration, API key setup, and correlation rules. The repository README gives the quick-start steps, and the wiki holds the detailed reference.

For Kali-specific notes, the Kali Linux tools site lists the SpiderFoot package, its binaries, and its dependencies. Read both sources when you configure modules or troubleshoot a failed scan.

Community

The SpiderFoot community gathers on GitHub, where users report issues, request features, and submit code. The project accepts pull requests, so developers extend the framework with new modules and correlation rules. Active maintenance keeps the tool current with new data sources and fixes.

Beyond GitHub, OSINT practitioners discuss SpiderFoot on security forums and Reddit threads, where users compare module setups and share scan strategies. These discussions help new users learn which modules fit which investigation.
