Criptografia com força inadequada

Ocorre quando um desenvolvedor implementa criptografia, mas usa algoritmos, tamanhos de chave ou modos de operação insuficientes para proteger dados sensíveis contra força bruta ou criptoanálise. Um exemplo clássico é usar DES em vez de AES, ou chaves RSA de 512 bits quando o padrão mínimo aceitável é 2048 bits.

Exemplo

Uma aplicação que armazena senhas usando MD5 ou SHA-1 sem salt, ou que criptografa dados de cartão de crédito com AES-128 quando deveria ser AES-256. Um atacante consegue quebrar essas chaves com recursos computacionais modernos em tempo viável.

Como mitigar

Use algoritmos criptográficos modernos e fortes: AES-256 para simetria, RSA-2048 (ou superiores) para assimetria, bcrypt/Argon2 para hashing de senhas, e sempre com salt ou IV aleatório. Siga as recomendações de órgãos como NIST ou BSI para tamanhos mínimos de chave.
