A eMudhra publicou uma declara\u00e7\u00e3o relacionada ao incidente em que oito certificados raiz de uma autoridade certificadora possu\u00edam chaves privadas de f\u00e1cil decifra\u00e7\u00e3o, com apenas 1 byte de entropia em vez de 48. A eMudhra afirma que os certificados foram gerados em abril de 2025 durante uma cerim\u00f4nia p\u00fablica utilizando m\u00f3dulos de seguran\u00e7a de hardware (HSM) que possuem certificado de conformidade com os requisitos FIPS 140-2 N\u00edvel 3. <\/p>\n

Durante o processo de gera\u00e7\u00e3o das chaves, ocorreu uma falha que resultou na cria\u00e7\u00e3o de um segundo conjunto de chaves fracas, com bytes mais significativos zerados, al\u00e9m do conjunto principal de chaves criptograficamente seguras. Isso aconteceu na etapa de embalagem\/desembalagem no HSM (wrap\/unwrap, criptografia e descriptografia com a chave envolt\u00f3ria) e essas chaves fracas foram utilizadas nos certificados. A falha n\u00e3o foi detectada, uma vez que as chaves privadas s\u00e3o criadas e armazenadas apenas no HSM, n\u00e3o saindo em forma aberta. A causa dessa falha ainda n\u00e3o est\u00e1 clara e a empresa est\u00e1 conduzindo uma investiga\u00e7\u00e3o relacionada. Afirma-se que os certificados raiz problem\u00e1ticos, criados utilizando as chaves fracas, passaram por uma auditoria independente e permaneceram na lista de confi\u00e1veis em todos os reposit\u00f3rios de certificados raiz por dois anos.
