theHarvester is an open-source OSINT (Open-Source Intelligence) tool written in Python, pre-installed on Kali Linux designed for gathering publicly available information about a target domain or company. It collects data such as email addresses, subdomains, virtual hosts, open ports, banners, and employee names from sources like search engines (e.g., DuckDuckGo, Bing), Shodan, and breach databases. With a modular architecture, it supports over 30 data sources, including Censys, VirusTotal, and crt.sh, enabling efficient reconnaissance for penetration testing and cybersecurity research. Features include DNS brute-forcing, API endpoint scanning, screenshot capture, and JSON/XML output for reporting. Maintained by Christian Martorella theHarvester is ideal for ethical hackers and security analysts, offering a lightweight, command-line interface with RESTful API support via restfulHarvest.

Wordlists is an essential package in Kali Linux (version 2023.2.0), crafted for cybersecurity professionals and penetration testers. This pre-compiled wordlist collection for brute-force attacks includes the renowned rockyou.txt with 14.3 million passwords, making it a leading password-cracking resource for ethical hacking. With a 50.90 MB footprint and support for tools like John the Ripper, Wordlists streamlines security testing, helping identify weak credentials efficiently.
