Uso de algoritmo criptográfico fraco ou quebrado

É quando o código utiliza algoritmos de criptografia que foram comprometidos, obsoletos ou nunca foram seguros (como MD5, DES, SHA-1 em contextos sensíveis). Esses algoritmos permitem que um atacante recupere dados criptografados com esforço computacional viável, invalidando a proteção que deveriam oferecer.

Ejemplo

Uma aplicação bancária que criptografa senhas usando MD5 ou MD5(senha + salt), ou que negocia conexão HTTPS com suporte a TLS 1.0. Em ambos os casos, ferramentas públicas conseguem quebrar a proteção em horas ou minutos.

Cómo mitigar

Use algoritmos atuais: SHA-256+ (ou bcrypt/scrypt) para hashing de senhas, AES-256 para dados em repouso, e TLS 1.2+ (idealmente 1.3) para trânsito. Revise regularmente o padrão NIST ou recomendações do OWASP e retire suporte a algoritmos deprecados das suas dependências e configurações.
