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.

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 · 56 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 56. The rest are reachable from any of them.
