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.

Shared TLS certificate · 1 host

These hosts served the same certificate. That is the strongest link this corpus can draw between two addresses, though it evidences a shared BUILD rather than a shared operator: a leaked or resold profile puts the same certificate in different hands. Full cohort →

Shared JA4X issuance template · 154 hosts

These hosts issued certificates from the same template — the same distinguished-name fields hashed in the same order. It links tooling, not necessarily an operator. Full cohort →

Showing 24 of 154. Full cohort →

Neighbourhood · 207.56.28.0/24 · 3 hosts

3 other confirmed hosts in the same /24. Adjacent addresses under one operator are a different signal from a shared certificate — they suggest a block, not a build.
