theHarvester vs Scalpel: Which Browser Extension tool is Best in 2025?

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.

Scalpel is an open-source, high-performance file carving utility pre-installed on Kali Linux at /usr/bin/scalpel, designed for recovering deleted or hidden files from disk images and raw block devices. Developed by Golden G. Richard III as an enhanced rewrite of Foremost 0.69, Scalpel leverages header and footer signatures to extract files, bypassing file system metadata. Supporting formats like JPEG, PDF, MP3, and DOC, it’s a critical tool for digital forensic investigators, incident responders, and ethical hackers conducting cyber forensic investigations and file recovery. Scalpel’s multithreading, GPU acceleration, and regular expression support make it exceptionally fast and versatile.
