IANA-registered to Hiperscan for an "Identification Service"; the UDP side is Reserved.
TCP 8293 carries the registered name hiperscan-id, "Hiperscan Identification Service", registered in December 2009 by Hiperscan GmbH, a maker of handheld near-infrared spectrometers used to identify substances. UDP 8293 is marked Reserved rather than assigned. No protocol specification is published and no widely deployed software claims the port; Nmap sees it open on about 0.015% of scanned hosts. If you find it listening, the registry name almost certainly does not describe what is there.
Expose with care
An unidentified listener in practice. Find the owning process before exposing it beyond a local network.
