Shared TLS certificate · 99 hosts

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 →

Showing 24 of 99. Full cohort →

Shared JA4X issuance template · 270 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 →

Shared Cobalt Strike watermark · 108 hosts

A watermark identifies the Cobalt Strike licence a beacon was generated from. Hosts sharing one were built from the same copy of the software — which is not the same as one operator, since cracked and leaked builds circulate widely and share a watermark by definition.

Showing 24 of 108. The rest are reachable from any of them.
