# 1. Reconnaissance Reconnaissance is all about collecting information about your target. Generally speaking, reconnaissance usually involves no interaction with the target(s) or system(s). There are some specialized tools that we can utilize but for this introduction, it is good to know the following tools. * Google (specifically Google Dorking) * Wikipedia * PeopleFinder.com * who.is * sublist3r * Sublist3r is a fantastic python script that allows us to perform quick and easy recon against our target, discovering various subdomains associated with the websites/domains in scope. * hunter.io * builtwith.com * wappalyzer --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
