    Looks for API keys, credentials, and secrets hidden in JavaScript code.

  • CTFR
    Leverages Certificate Transparency logs to find subdomains others miss.

  • JSParser
    Parses JavaScript files to locate potential endpoints and parameters.

:toolbox: Exploitation & Testing

  • XSStrike
    Intelligent XSS exploitation tool with fuzzing, context analysis, and payload generation.

  • Dalfox
    A modern XSS scanner that handles DOM-based and reflected variants with smart detection.

  • SQLMap
    Feature-rich tool to detect and exploit SQL injection vulnerabilities with automation.

  • ffuf (Fuzz Faster U Fool)

  • tplmap
    Finds and exploits Server-Side Template Injection (SSTI) vulnerabilities.

  • Smuggler
    Automates HTTP Request Smuggling detection, effective against older reverse proxies.

  • dirsearch
    CLI-based web path scanner that identifies hidden files, directories, and misconfigs.

  • jwt_tool
    Exploits JWT (JSON Web Token) flaws such as alg none or weak secrets.

:counterclockwise_arrows_button: Workflow Automation & Management

  • Bugbounty-Toolkit
    An automated toolkit with predefined bug bounty scripts, tools, and wordlists.

  • bbmonitor
    Continuously tracks new scopes on bounty platforms and alerts users.

  • bountyplz
    Automatically applies to private programs on HackerOne with a custom message.

  • Metabigor
    Performs metadata gathering and recon from IPs, ASN, CIDR, etc.

  • Chaos
    Access ProjectDiscovery’s massive subdomain datasets through the Chaos API.

  • Slack Pirater
    Looks for leaked Slack tokens or endpoints exposed on open sites.

  • Notify
    Create custom notification pipelines for tool alerts (email, Slack, Discord, etc.).

:locked_with_key: Niche, CMS, or Framework-Specific Tools

  • Drupwn
    Scans Drupal-based sites for known CVEs and exploits.

  • WPScan
    The best tool for auditing WordPress vulnerabilities, plugins, and themes.

  • joomscan
    Performs vulnerability analysis on Joomla sites.

  • CMSmap
    A penetration testing tool for multiple CMS systems: WordPress, Joomla, Drupal.

  • WhatWeb
    Identifies technologies and frameworks used on a website, helpful for target profiling.

:white_check_mark: Final Note

This master list bridges gaps in common bug bounty toolkits—offering highly valuable tools often overlooked in traditional guides. Whether you’re automating recon, fingerprinting technologies, fuzzing parameters, or exploiting deep vulnerabilities, these tools give you the strategic edge.

:light_bulb: Tip: Use tools like tmux, GNU parallel, or interlace to run multiple tools simultaneously—supercharging automation without slowing performance.

Maintain ethics, stick to authorized scopes, and always report responsibly. Let your toolkit evolve as your skillset sharpens.

Stay sharp, automate smart, and always respect platform scopes and policies.
