Technical Details

what runs on :3679

IANA lists Newton Dock on both TCP and UDP port 3679. The service belongs to the Apple Newton docking ecosystem: a Newton device and compatible host software communicate using Newton-specific exchanges, rather than a general-purpose protocol such as HTTP. It has no standard TLS protection, and there is no broadly deployed modern service or generic banner expected on this port; the exact behavior depends on the Newton host software.

Security Information

exposure of :3679

risk score

routine exposure. this port is rarely the way in on its own — keep it patched and logged and move on.

network services averages 2.7 across 1,427 ports — this one sits 1.7 below.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

Treat Newton Dock traffic as unencrypted legacy device traffic. A compatible listener could participate in docking operations involving a Newton device and its data, so keep it on a trusted local network and do not expose it to the internet. The service is sufficiently rare that exposure is unlikely on contemporary systems, and no specific widespread exploit is established here.
