A universal, adaptive data acquisition framework designed for comprehensive information acquisition from multiple sources including GitHub, network mapping platforms (FOFA, Shodan), and arbitrary web endpoints. While the current implementation focuses on AI service provider key discovery as a practical example, the framework is architected for extensibility to support diverse data acquisition scenarios.

⭐⭐⭐ If this project helps you, please give it a star! Your support motivates us to keep improving and adding new features.

The system aims to build a universal data acquisition framework primarily targeting:

• GitHub: Code repositories, issues, commits, and API endpoints
• Network Mapping Platforms:
  • FOFA - Cyberspace mapping and asset discovery
  • Shodan - Internet-connected device search engine
• Arbitrary Web Endpoints: Custom APIs, web services, and data sources
• Extensible Architecture: Plugin-based system for easy integration of new data sources

1. Installation

   git clone https://github.com/wzdnzd/harvester.git
   cd harvester
   pip install -r requirements.txt

2. Configuration

Choose one of the following methods to create your configuration

1. Real-time Monitoring

   • Task status tracking
   • Performance metrics collection
   • Resource usage monitoring
   • Alert system

2. Configuration Flexibility

   • Multi-provider configuration
   • Custom search patterns
   • Adjustable performance parameters
   • Dynamic resource allocation

3. Extensibility

   • Plugin-style providers
   • Custom pipeline stages
   • Configurable monitoring system
   • Flexible recovery strategies

# Issue: pip install fails
# Solution: Upgrade pip and use virtual environment
python -m pip install --upgrade pip
python -m venv venv

# Linux/macOS
source venv/bin/activate

# Windows
venv\Scripts\activate

pip install -r requirements.txt

# Issue: Configuration validation fails
# Solution: Validate configuration file
python main.py --validate

# Issue: Missing configuration file
# Solution: Create from example
cp examples/config-simple.yaml config.yaml

# Issue: Too many API requests
# Solution: Adjust rate limits in config
rate_limits:
  github_api:
    base_rate: 0.1  # Reduce rate
    adaptive: true  # Enable adaptive limiting

# Issue: High memory usage
# Solution: Reduce batch sizes and thread counts
pipeline:
  threads:
    search: 1
    gather: 2  # Reduce from default
persistence:
  batch_size: 25  # Reduce from default 50

# Issue: Connection timeouts
# Solution: Increase timeout values
api:
  timeout: 60  # Increase from default 30
  retries: 5   # Increase retry attempts

# Enable debug logging
python main.py --log-level DEBUG

# Save debug output to file
python main.py --log-level DEBUG > debug.log 2>&1

• Never commit credentials to version control
• Use environment variables for sensitive configuration
• Rotate credentials regularly to minimize exposure risk
• Implement least privilege access for API keys

# Example: Secure credential configuration
global:
  github_credentials:
    sessions:
      - "${GITHUB_SESSION_1}"  # Use environment variables
      - "${GITHUB_SESSION_2}"
    tokens:
      - "${GITHUB_TOKEN_1}"

• Respect robots.txt and website terms of service
• Implement rate limiting to avoid overwhelming target services
• Log redaction automatically removes sensitive data from logs
• Data retention policies should comply with applicable regulations

• Review legal requirements before using in production
• Obtain necessary permissions for data collection
• Implement data anonymization where required
• Document data processing activities for compliance

1. Limitations

   • Respect Github API usage limits
   • Configure rate limits appropriately
   • Mind memory usage
   • Handle sensitive data carefully

2. Best Practices

   • Use appropriate thread counts
   • Backup results regularly
   • Monitor error rates
   • Handle alerts promptly

• Abstract Data Source Interface: Create a unified interface for all data sources
  • Define DataSourceProvider base class with standard methods (search, gather, validate)
  • Implement adapter pattern for different API formats (REST, GraphQL, WebSocket)
  • Add configuration schema for data source registration
  • Support dynamic data source loading and hot-swapping

• Flexible Stage Definition: Move beyond the current 4-stage limitation
  • Create StageDefinition configuration format (YAML/JSON)
  • Implement dynamic stage loading from configuration files
  • Add stage composition and conditional execution
  • Support user-defined stage workflows and DAG customization

• Pluggable Processing Architecture: Replace fixed function calls with configurable handlers
  • Implement HandlerRegistry for stage-specific processors
  • Create ProcessorInterface with standardized input/output contracts
  • Add handler discovery mechanism (annotation-based or configuration-driven)
  • Support middleware chains for request/response processing

• FOFA Integration

  • Implement FOFA API client with authentication
  • Add FOFA-specific query optimization

• Shodan Integration

  • Support data querying and extraction from Shodan

• Universal Web Scraper
  • Build configurable web scraping engine
  • Add support for JavaScript-rendered content (Selenium/Playwright)
  • Implement anti-bot detection bypass mechanisms
  • Create content extraction rule engine

• Plugin System
  • Design plugin architecture with lifecycle management
  • Create plugin marketplace and discovery mechanism
  • Add plugin sandboxing and security validation
  • Implement plugin dependency resolution

• Distributed Processing
  • Add support for distributed task execution (Celery/RQ)
  • Implement horizontal scaling with load balancing
  • Create cluster management and node discovery
  • Add distributed state synchronization

• Enhanced Security Features
  • Implement credential encryption and secure storage
  • Create rate limiting policies per data source

• Real-time Analytics Dashboard
  • Build web-based monitoring interface
  • Add real-time metrics visualization
  • Implement alerting and notification system
  • Create performance profiling and bottleneck analysis

• RESTful API Server
  • Build comprehensive REST API for external integration
  • Implement webhook support for real-time notifications
  • Create SDK libraries for popular programming languages
