Chave criptográfica hardcoded

É quando a chave ou senha usada para criptografia fica embutida no código-fonte ou binário da aplicação. Qualquer pessoa com acesso ao código (incluindo atacantes que fazem engenharia reversa) consegue extrair a chave e descriptografar todos os dados protegidos por ela, anulando completamente a proteção criptográfica.

Example

Um app mobile que faz login criptografa a senha com uma chave fixa como `const ENCRYPTION_KEY = '12345abc'` no código. Um atacante faz dump do APK, encontra a chave em minutos, e consegue descriptografar todas as senhas armazenadas de todos os usuários.

How to mitigate

Armazene chaves em repositórios seguros (key management systems, vaults como AWS Secrets Manager ou HashiCorp Vault), derive chaves de senhas do usuário com algoritmos fortes (PBKDF2, Argon2), ou use mecanismos de derivação dinâmica. Nunca coloque chaves no código, comentários ou arquivos de configuração versionados.
