About

Inspired by Cybergordon and IntelOwl.

This project aims to provide a simple and efficient way to check the reputation of your observables using multiple services, without having to deploy a complex solution. Read the docs at https://docs.cyberbro.net/

[!TIP] To build custom reports, use Cyberbro with your favorite LLM (Claude, OpenAI gpt-5...) via MCP (Model Context Protocol)
Checkout Cyberbro MCP for more information.

Demo

Features

• Easy Input: Paste raw logs or IoCs-automatic parsing and extraction.
• Multi-Service Checks: Reputation lookup for IPs, hashes, domains, URLs, and Chrome extension IDs across many threat intel services.
• Comprehensive Reports: Advanced search, filtering, and export to CSV/Excel.
• Fast Processing: Multithreaded for speed.
• Automated Pivoting: Discover related domains, URLs, and IPs via reverse DNS and RDAP / Whois.
• Accurate Domain & Abuse Info: RDAP / Whois and abuse contact lookups.
• Integrations: Microsoft Defender for Endpoint, CrowdStrike, OpenCTI, Grep.App, Hudson Rock, and more.
• Proxy & Storage: Proxy support and results stored in SQLite.
• History & Graphs: Analysis history and experimental graph view.
• Cache: Caching for faster repeat lookups (enabled at multi-engines level, not each engine).

What Makes Cyberbro Unique

• Beginner-Friendly: Accessible for all skill levels.
• Chrome Extension ID Lookup: Get extension names and CTI data from IDs.
• Lightweight Deployment: Simple setup and use.
• Advanced TLD Extraction: Accurate root domain detection for better lookups.
• Pragmatic Data Gathering: Uses GitHub and Google to find overlooked IoCs.
• CTI Report Integration: Fetches IoC-related reports from IoC.One.
• EDR Integration: Checks observables against your own security tools (MDE, CrowdStrike).

Getting Started - TL;DR

[!TIP] If you are lazy, you need Docker.
Do a git clone ; copy .env.sample to .env ; docker compose up then go to localhost:5000. Yep, that's it!

Getting Started

• To get started, clone the repository

git clone https://github.com/stanfrbd/cyberbro
cd cyberbro

Edit the config file (mandatory)

cp .env.sample .env

[!NOTE] Don't have API keys? No problem, just copy .env.sample to .env and leave optional values empty. Be careful if a proxy is used.
You will be able to use all free engines!

• Fill values (including proxy if needed) in the .env file.

[!WARNING] .env contains sensitive secrets and must never be committed. For production/team deployments, use SOPS, Vault, or an equivalent secret manager workflow.

[!IMPORTANT] Starting with version v0.13.0, Cyberbro no longer supports secrets.json and the /config page. Cf. discussion 165.
If you already have a legacy secrets.json, convert it to .env with: python3 scripts/secrets_json_to_env.py

See Advanced options for deployment in the docs.

Launch the app

Lazy and easy - use docker

[!WARNING] Make sure you install the compose plugin as docker compose and not docker-compose. In Docker, the app binds to 0.0.0.0 inside the container even if your local .env sets FLASK_HOST=127.0.0.1.

docker compose up # use -d to run in background and use --build to rebuild the image

• Go to http://127.0.0.1:5000 and Enjoy.

Don't forget to edit .env before building the image.

See Advanced options for deployment in the docs to get all Docker deployment options.

The old way

• Clone the repository and install the requirements.

You might want to create a venv before installing the dependencies.

pip install -r requirements.txt

• Run the app with gunicorn (clean mode).

gunicorn -c prod/gunicorn.conf.py app:app

• Run the app with in development mode.

python3 app.py

[!CAUTION] If you intend to use this in a production environment, use well configured Reverse Proxy + WAF to prevent security issues.

Cyberbro API

• The API is available at /api/ and can be accessed via the GUI or command-line.

There are currently 3 endpoints:

• /api/analyze - Analyze a text and return analysis ID (JSON).
• /api/is_analysis_complete/<analysis_id> - Check if the analysis is complete (JSON).
• /api/results/<analysis_id> - Retrieve the results of a previous analysis (JSON).

curl -X POST "http://localhost:5000/api/analyze" -H "Content-Type: application/json" -d '{"text": "cyberbro.net", "engines": ["reverse_dns", "rdap_whois"]}'

{
  "analysis_id": "e88de647-b153-4904-91e5-8f5c79174854",
  "link": "/results/e88de647-b153-4904-91e5-8f5c79174854"
}

{

Special thanks

A huge thank you to all the amazing contributors who made pull requests and helped improve this project:

• Florian PILLOT who reworked engines (refactoring and optimizations).
• Axel who develops Ioc.One and added a specific User-Agent allowing scraping of Ioc[.]One.
• Jon Mark Allen who added a better secret management and tests. He refactored a lot and made many improvements to the codebase, including CriminalIP.
• cirosec GmbH - Felix Friedberger for adding crt.sh engine.
• Stig Dahl for enhancing crt.sh engine, adding DFIR IRIS search and fixing Bandit issues, correcting MISP engine, adding MISP Feedback engine.
• 0xffr for fixing issue #98 - Grep.app engine broken and commenting properly in CriminalIP engine.
• Maxime Berthault - Maxou56800 for developing Cyberbro CLI.

Your contributions are greatly appreciated!
