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.
