Vediamo Whatweb che non è affatto WhatsApp Web, consentitemi la battuta 😄 per certi versi simile a Dirb e che offre funzionalità molto interessanti! Whatweb è presente di default fra i "Kali Linux Tools" .
Whatweb si presenta con questo slogan:
Next generation web scanner.
Identify the technology stack that powers a website and explore the Web of Things.
L'installazione su Debian-based è semplicemente sudo apt install whatweb
facendo eventualmente attenzione alle dipendenze, indicate nella precedente documentazione. In alternativa da GitHub, git clone https://github.com/urbanadventurer/WhatWeb
e poi secondo quanto indicato da INSTALL.md, sudo make install
.
Vediamo un'immagine, script di codice per l'esattezza, di come Whatweb si presenta nel terminale:
