What is Nefarious?
Nefarious is an open source web crawling and scraping framework written in Python. It provides capabilities for recursively crawling websites and extracting data from pages including text content, links, images, documents, and more. Some key features include:
- Modular architecture for developing custom crawlers and scrapers
- Easy configuration using YAML files
- Plugin support for extending functionality
- Built-in scraping primitives for common data types
- Multi-threaded for high performance
- Integrations for scraping JavaScript pages
Nefarious can be useful for building legal search engines, archiving public online content, and analyzing website data. However, its powerful capabilities could also be misused for unauthorized access or scraping of private/protected data. It is important that Nefarious is used legally and ethically considering a website's terms of service and restrictions.
