subsurfer 1.2.2

Red Teaming and Web Bug Bounty Fast Asset Identification Tool

🏄‍♂️ SubSurfer

SubSurfer is a fast and efficient subdomain enumeration and web property identification tool.

🌟 Features

• Red Team/Bug Bounty Support: Useful for both red team operations and web bug bounty projects
• High-Performance Scanning: Fast subdomain enumeration using asynchronous and parallel processing
• Port Scanning: Expand asset scanning range with customizable port selection
• Web Service Identification: Gather environmental details such as web servers and technology stacks
• Pipeline Integration: Supports integration with other tools using -pipeweb and -pipesub options
• Modular Design: Can be imported and used as a Python module
• Continuous Updates: - Continuous Updates: New passive/active modules will continue to be added

🚀 Installation

bash

git clone https://github.com/arrester/subsurfer.git
cd subsurfer

or

Python

pip install subsurfer

📖 Usage

CLI Mode

Basic Scan
subsurfer -t vulnweb.com

Enable Active Scanning
subsurfer -t vulnweb.com -a

Include Port Scanning
subsurfer -t vulnweb.com -dp # Default Port
subsurfer -t vulnweb.com -p 80,443,8080-8090 # Custom ports

Pipeline Output
subsurfer -t vulnweb.com -pipeweb # Output only web server
subsurfer -t vulnweb.com -pipesub # Output only subdomain results

Using as a Python Module

Subdomain Scan

from subsurfer.core.controller.controller import SubSurferController
import asyncio

async def main():
    controller = SubSurferController(
        target="vulnweb.com",
        verbose=1,
        active=False            # Active Scan Option
    )
    
    # Collect subdomains
    subdomains = await controller.collect_subdomains()
    
    # Print results
    print(f"Discovered Subdomains: {len(subdomains)}개")
    for subdomain in sorted(subdomains):
        print(subdomain)

if __name__ == "__main__":
    asyncio.run(main())

Port Scan

from subsurfer.core.controller.controller import SubSurferController
import asyncio

async def main():
    controller = SubSurferController(
        target="vulnweb.com",
        verbose=1
    )
    
    # Collect subdomains
    subdomains = await controller.collect_subdomains()
    
    # Default ports (80, 443)
    ports = None

    # Set port scan options
    # ports = controller.parse_ports()  # Default ports
    # Or specify custom ports
    # ports = controller.parse_ports("80,443,8080-8090")
    
    # Web service scanning
    web_services = await controller.scan_web_services(subdomains, ports)
    
    # Print web servers
    print("\n웹 서버:")
    for server in sorted(web_services['web_servers']):
        print(f"https://{server}")
    
    # Print active services
    print("\n활성화된 서비스:")
    for service in sorted(web_services['enabled_services']):
        print(service)
        
    # Print discovered URLs and ports
    print("\n발견된 URL:")
    for subdomain, urls in web_services['all_urls'].items():
        for url, port in urls:
            print(f"{url}:{port}")

if __name__ == "__main__":
    asyncio.run(main())

Result Save

from subsurfer.core.controller.controller import SubSurferController
import asyncio

async def main():
    controller = SubSurferController("vulnweb.com")
    
    # Collect subdomains and scan web services
    subdomains = await controller.collect_subdomains()
    web_services = await controller.scan_web_services(subdomains)
    
    # Save results
    results_dict = {
        'subdomains': subdomains,
        'web_services': web_services.get('web_services', {}),
        'web_servers': web_services.get('web_servers', set()),
        'enabled_services': web_services.get('enabled_services', set()),
        'all_urls': web_services.get('all_urls', {})  # Includes URL and port information
    }
    
    # Generate default result file path (stored in the "results" directory)
    output_path = controller.get_output_path()
    controller.save_results(results_dict, output_path)

if __name__ == "__main__":
    asyncio.run(main())
