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.

Neighbourhood · 185.92.190.0/24 · 4 hosts

4 other confirmed hosts in the same /24. Adjacent addresses under one operator are a different signal from a shared certificate — they suggest a block, not a build.
