DigiCert: Internal Domain Name cert mis-issuance

DigiCert experienced a mis-issuance of a certificate containing an internal domain name due to a gap in their domain pre-validation process. The issue was reported by a third party on October 16, 2018, leading to an investigation that revealed a validation agent's override of the domain's classification. The certificate was revoked on October 17, 2018, and DigiCert implemented fixes to prevent similar occurrences in the future.

1. 2018-10-16 Third party reported internal domain name on a certificate.
2. 2018-10-17 Certificate revoked and pre-issuance checks improved.
