Folha de Dicas do W3af Web Application Attack Framework

Visão Geral

W3af (Web Application Attack and Audit Framework) é um scanner de segurança de aplicações web abrangente e de código aberto. Ele fornece uma estrutura completa para encontrar e explorar vulnerabilidades em aplicações web, com plugins de descoberta, auditoria e ataque para avaliações de segurança abrangentes.

⚠️ Aviso: Esta ferramenta destina-se apenas a testes de penetração autorizados e avaliações de segurança. Certifique-se de ter autorização adequada antes de usar contra qualquer alvo.
