  • BBOT: The Swiss Army Knife for Recon, Bug Bounties, and ASM

    Meet BBOT: Your New Favorite Recon Tool

    BBOT (short for Bee·bot) is a powerful, multipurpose Python-based scanner designed to automate recon, bug bounty hunting, and attack surface management (ASM). Inspired by tools like Spiderfoot but modernized for today’s needs, BBOT delivers speed, modularity, and scalability for cybersecurity professionals and hobbyists alike.

    With native support for multiple targets, extensive output options, and seamless integration with popular APIs, BBOT is more than a tool-it’s a full-fledged recon framework that adapts to your workflow.

    Why BBOT?

    Reconnaissance is the foundation of offensive security. BBOT streamlines this critical phase with:

    • Subdomain enumeration that consistently outperforms other tools
    • Web spidering and email harvesting
    • Light and aggressive web scanning presets
    • YAML-driven customization with modular architecture
    • Support for over a dozen output formats including Neo4j, CSV, JSON, and Splunk

    Installation Made Simple

    To get started with BBOT, simply run:

    pipx install bbot

    For the latest development version:

    pipx install --pip-args '--pre' bbot

    Docker images and advanced installation options are available via the official Getting Started guide.

    Core Features & Usage Examples

    Subdomain Enumeration

    Discover subdomains using passive APIs and brute-force techniques:

    bbot -t evilcorp.com -p subdomain-enum

    BBOT finds 20-50% more subdomains than other tools, especially on larger domains.

    Web Spidering

    Extract emails and files by crawling target websites:

    bbot -t evilcorp.com -p spider

    Email Harvesting

    Scrape email addresses from web content and APIs:

    bbot -t evilcorp.com -p email-enum

    Web Scanning

    Run lightweight or aggressive web scans:

    bbot -t www.evilcorp.com -p web-basic
bbot -t www.evilcorp.com -p web-thorough

    Everything at Once

    For comprehensive recon in one go:

    bbot -t evilcorp.com -p kitchen-sink --allow-deadly

    Targets and Scope

    BBOT accepts a wide range of target types, including:

    • Domains (e.g. evilcorp.com)
    • IP ranges (e.g. 1.2.3.0/24)
    • URLs, emails, organizations, usernames
    • Even mobile app package names and file paths

    Define scope via command-line or config files to keep scans focused and efficient.

    Output Options

    BBOT can export scan data to:

    • Neo4j, Elasticsearch, and Splunk for advanced querying
    • Slack, Discord, and Microsoft Teams for real-time alerts
    • SQL databases and CSV/JSON files for storage and analysis

    Security and Dependencies

    BBOT supports API key configuration for services like Shodan, VirusTotal, and SecurityTrails. Keys can be added to your ~/.config/bbot/bbot.yml file or passed directly via the command line.

    All dependencies are auto-installed, and Ansible scripts are provided for streamlined environment setup.

    Python API for Developers

    Use BBOT as a library for custom applications. Both synchronous and asynchronous scanning are supported:

    from bbot.scanner import Scanner
scan = Scanner("evilcorp.com", presets=["subdomain-enum"])

    Community & Contributions

    BBOT thrives on community contributions-from module ideas to code enhancements. Check out the developer docs to get involved.

    Final Thoughts

    BBOT isn’t just another recon tool. It’s a flexible, extensible framework built for modern offensive security workflows. Whether you’re working on bug bounties or managing enterprise attack surfaces, BBOT gives you the power to automate and innovate your reconnaissance efforts.

  • Subfinder: Fast, Passive Subdomain Enumeration for Bug Bounty and Pentesting

    Discover Subdomains the Smart Way with Subfinder

    Whether you’re into bug bounty hunting, penetration testing, or just love exploring internet surface area, Subfinder by ProjectDiscovery is a must-have tool in your cybersecurity toolkit. This open-source tool specializes in passive subdomain enumeration, making it ideal for stealthy and efficient reconnaissance.

    Purpose and Use Cases

    Subfinder is designed to find valid subdomains of target domains using passive online sources. This means it doesn’t send direct queries to the target infrastructure, making it stealthy and low-risk for detection. It’s perfect for:

    • Bug bounty hunters identifying attack surfaces
    • Penetration testers performing reconnaissance
    • Security analysts mapping domain assets
    • Red teamers staying under the radar

    Installation and Setup

    Installing Subfinder is straightforward. Make sure you have Go 1.21 or later installed, then run:

    go install -v github.com/projectdiscovery/subfinder/v2/cmd/subfinder@latest

    After installation, you can run Subfinder directly. However, to maximize its power, some passive data sources require API keys. Learn more about setting up provider configurations here: Post-Install Configuration.

    Core Features

    • Blazing fast performance with optimized modules
    • Curated passive sources like crt.sh and GitHub for rich subdomain data
    • Multiple output formats: JSON, text files, standard output
    • Wildcard and DNS resolution support for filtering noise
    • STDIN/STDOUT compatibility for smooth automation and scripting
    • Recursive subdomain support for deeper discovery

    Example Commands

    Run Subfinder on a single domain:

    subfinder -d example.com

    Scan a list of domains:

    subfinder -dL domains.txt

    Use all sources (slow but comprehensive):

    subfinder -d example.com -all

    Exclude noisy or unreliable sources:

    subfinder -d example.com -es alienvault,zoomeyeapi

    Output results to a file:

    subfinder -d example.com -o results.txt

    Security Considerations

    Since Subfinder performs only passive reconnaissance, it’s inherently safe and doesn’t alert targets. However, be cautious when integrating it with active tools or APIs that may log access or trigger alerts.

    Technical Terms Explained

    • Passive Enumeration: Gathering data from third-party sources without direct interaction with the target system.
    • Wildcard Domains: DNS records that match multiple subdomains; filtering these reduces false positives.
    • Resolvers: DNS servers used to resolve domain names into IP addresses, used in validation steps.
    • STDIN/STDOUT: Standard input/output – useful for chaining Subfinder with other tools in shell pipelines.

    Library Use for Developers

    Subfinder can also be integrated into Go applications as a library. Minimal examples of SDK usage are available in the Subfinder GitHub examples directory.
