Recon

Reconnaissance is the first and arguably most important phase of any security assessment. It involves systematically discovering and mapping a target's attack surface — subdomains, IP ranges, open ports, running services, technology stacks, and exposed endpoints — before any active testing begins.

Effective recon separates productive security testing from wasted effort. A thorough recon phase reveals forgotten assets, shadow IT, staging environments, and legacy systems that are often less hardened than primary applications. Many of the highest-impact bug bounty findings come from assets discovered during recon that other hunters overlook.

Modern recon combines passive and active techniques. Passive recon leverages certificate transparency logs, DNS records, web archives, search engine indexes, and public datasets to map infrastructure without touching the target. Active recon involves subdomain brute-forcing, port scanning, directory fuzzing, and technology fingerprinting. Tools like subfinder, httpx, nuclei, katana, and ffuf form the backbone of most researchers' recon pipelines.

Automation is essential at scale. Many hunters build continuous recon pipelines that monitor targets for new subdomains, changed DNS records, and newly exposed services — enabling them to test fresh attack surface before anyone else.

This page collects recon methodologies, tool guides, automation workflows, and techniques for comprehensive attack surface discovery.

Frequently Asked Questions

What is reconnaissance in security testing?
Reconnaissance is the process of discovering and mapping a target's attack surface before active testing. It includes finding subdomains, IP ranges, open ports, running services, technology stacks, and exposed endpoints. Thorough recon is often the difference between finding critical vulnerabilities and finding nothing.
What are the essential recon tools?
Core tools include subfinder and amass for subdomain enumeration, httpx for live host discovery, nmap for port scanning, nuclei for automated vulnerability scanning, katana and gospider for web crawling, ffuf for directory fuzzing, and waybackurls for historical URL discovery. Most hunters combine these into automated pipelines.
What is continuous recon and why does it matter?
Continuous recon monitors targets for changes over time — new subdomains, changed DNS records, newly exposed services, or updated technologies. Many high-impact findings come from assets that just appeared. Hunters automate this with cron jobs or services like Chaos by ProjectDiscovery, alerting them to fresh attack surface before competitors.
