Transmissão de dados sensíveis em texto plano

A aplicação envia informações críticas (senhas, tokens, dados pessoais) sem criptografia em canais de comunicação que podem ser interceptados. Um atacante na rede consegue capturar esses dados diretamente, comprometendo a confidencialidade da informação e permitindo roubo de credenciais ou dados sensíveis.

Example

Um app mobile envia login e senha via HTTP (não HTTPS), ou um sistema transmite números de cartão de crédito em requisições não criptografadas. Ferramentas simples como Wireshark permitem capturar esse tráfego em redes abertas ou mesmo corporativas.

How to mitigate

Sempre usar HTTPS/TLS para qualquer transmissão de dados sensíveis, implementar pinning de certificado em apps mobile, validar certificados no lado cliente, e nunca transmitir segredos em URLs ou headers sem criptografia. Na prática: configure HTTPS em produção, force redirecionamento HTTP → HTTPS, e audite logs de requisições para detectar canais desprotegidos.
