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 Cobalt Strike watermark · 3 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.
