Technical Details

what runs on :5670

TCP port 5670 is assigned to FileMQ, a file publish-subscribe protocol built on ZeroMQ. A FileMQ implementation exchanges file-related messages over ZeroMQ's message transport, which uses a ZMTP handshake and message framing rather than an HTTP-style request/response exchange. Port 5670 is the registered endpoint, but the assignment does not guarantee that an implementation uses it as its default. The ZeroMQ transport does not encrypt traffic by default; encryption depends on the implementation and its configuration.

security overview

File contents and related messages should be treated as sensitive, and plain ZeroMQ TCP does not provide encryption by default. Do not expose a FileMQ listener to the public internet unless its implementation has appropriate access controls and protected transport; an reachable, inadequately protected service could allow unauthorized access to published material or file injection. Nmap scan data has not observed this port open, consistent with limited deployment.
