Wfuzz Cheat Sheet

Panoramica

Wfuzz è un web application fuzzer progettato per facilitare le valutazioni di applicazioni web. Può essere utilizzato per trovare risorse non collegate (directory, servlet, script, ecc.), effettuare bruteforce di parametri GET e POST, bruteforce di parametri di Form (Utente/Password), Fuzzing, ecc. Wfuzz è un potente strumento per scoprire contenuti nascosti, testare vulnerabilità e condurre valutazioni complete di sicurezza delle applicazioni web.

⚠️ Avvertenza: Utilizzare Wfuzz solo su applicazioni di proprietà o per le quali si ha un esplicito permesso di test. I test non autorizzati possono violare termini di servizio o leggi locali.
