theHarvester is a simple to use, yet powerful tool designed for the reconnaissance stage of red team assessments or penetration tests.
Features: It performs open source intelligence (OSINT) gathering to help determine a domain's external threat landscape.
Gathers: Names, emails, IPs, subdomains, and URLs using multiple public resources including crtsh, HackerTarget, RapidDNS, urlscan, Bing, and other curated sources.
Curated Scan: This tool runs theHarvester with 12 fast, keyless passive sources (crtsh, HackerTarget, RapidDNS, BufferOverrun, CertSpotter, urlscan, and more) ā chosen because they reliably return data without API keys.
Processing Time: OSINT gathering usually completes in 1-3 minutes depending on the domain size and available data.
Real-time Output: Results will stream live to the terminal below as they are discovered.
