Methodology — 5 phases

A structured web pentest always follows the same rhythm. In brief:

Phase

Goal

Tools

1. Reconnaissance

Map the attack surface without touching the target

crt.sh, Shodan, Whois, Certificate Transparency

Browser DevTools, JS analysis, ffuf

Burp Suite, Python scripts, Playwright

5. Report
