SpiderFoot is an open-source intelligence (OSINT) automation tool included in Kali Linux, designed to streamline the collection and analysis of publicly available data for reconnaissance. Written in Python 3, it integrates with over 200 modules to query more than 100 data sources, including Shodan, HaveIBeenPwned, and social media platforms, to gather information on targets like IP addresses, domains, email addresses, usernames, and phone numbers. SpiderFoot supports both offensive use (e.g., penetration testing) and defensive use (e.g., identifying organizational data leaks). It features a web-based GUI, command-line interface, and SQLite backend for storing scan results, with customizable modules and visualization options.

Bully is a robust open-source wireless network auditing tool for ethical hacking, seamlessly integrated into Kali Linux (version 2024.06.R1).
