Shared Cobalt Strike watermark · 6 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.

This page is generated from automated scanning and is publicly available. If you are responsible for this address and it should not be listed, write to support@publicmosaic.com — see abuse & takedown for what we need and what happens next, or opt-out to exclude a whole range from scanning.

Addresses are frequently compromised third-party hosts rather than infrastructure their owner stood up. A listing records what a scan observed at a point in time; it is not an allegation about whoever pays for the address.
