Falta de Proteção contra Tentativas Excessivas de Autenticação

É a ausência de mecanismos que limitam o número de tentativas de login ou autenticação em um curto período. Um atacante pode fazer força bruta (testar muitas senhas ou códigos) sem ser bloqueado, permitindo descobrir credenciais válidas ou contornar fatores de autenticação como OTP.

Example

Um sistema de login não bloqueia a conta após 5 tentativas erradas nem implementa delay progressivo. Um atacante automático testa 10 mil combinações de senha em minutos contra um usuário-alvo e consegue acesso. Ou um atacante bruta-força códigos de 2FA sem que o sistema limite as tentativas.

How to mitigate

Implemente bloqueio ou throttling: limitar tentativas (ex: máx 5 por minuto), aumentar delay entre tentativas, bloquear conta temporariamente após falhas consecutivas, usar CAPTCHA após N tentativas, e registrar/alertar sobre picos de tentativas suspeitas.
