The certificate names above were validated by the issuing authority at issuance. They describe the certificate, not conduct by the names' owner — a legitimately issued certificate can be deployed on a listed host by whoever holds its private key, so treat the name as a pivot to investigate rather than as an attribution.

The certificate names above are what the certificate ASSERTS, not proof this host owns them — a self-signed certificate can claim any subject, so treat a familiar name here as an impersonation attempt rather than an identity.
