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.

Addresses are frequently compromised third-party hosts rather than infrastructure their owner stood up. A listing records what a scan observed at a point in time; it is not an allegation about whoever pays for the address.
