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 · 1 host

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 →
