About port 144/tcp.

Updated  ·  Confidence: Medium

Port 144/tcp is registered with IANA under the service name uma, described as "Universal Management Architecture," with assignee and contact listed as Jay Whitney. The Reference, Registration Date, and Modification Date columns are all blank in the current IANA registry — no RFC or informational document backs the assignment, and no date of registration is recorded, so those fields are reported here as blank rather than guessed. The assignment is dual-registered: 144/udp carries an identical service name, description, and contact, which is the normal IANA pattern for a service that could run over either transport. Universal Management Architecture itself does not correspond to any widely documented, currently-deployed protocol or product that this research pass could confirm — it reads as a reserved, largely unused name rather than an active service family. Separately, older /etc/services files and some legacy port-reference lists associate port 144 with "news," referring to NeWS (the Network extensible Window System), a Sun Microsystems display-PostScript windowing protocol from the 1980s. That association predates or conflicts with the current IANA record and should be treated as historical folklore rather than the authoritative current registration — an analyst seeing 144/tcp open today should not assume either uma or NeWS software is actually running, since no current deployment evidence exists for either.

Primary use

registered under the name "Universal Management Architecture," but no widely documented, currently-active protocol or product using this name was identified in this research pass [Unknown]

Security implications

no CVEs, malware families, or documented exploitation specific to port 144/tcp were identified; given the obscurity of both the "uma" registration and the legacy NeWS association, an open port 144 is uncommon and unlikely to be immediately attributable to a specific active service [Unknown]

Typically seen on

no confirmed typical deployment context identified [Unknown]

Legacy/conflicting association
some older /etc/services files and third-party port lists associate port 144 with "news" (NeWS, Sun Microsystems' Network extensible Window System) — a historical, pre-registry association that conflicts with the current IANA uma entry and should not be treated as current

About port 144/udp.

Updated  ·  Confidence: Medium

Port 144/udp is registered with IANA under the service name uma, described only as "Universal Management Architecture," with assignee and contact both listed as Jay_Whitney and a blank Reference field — meaning no RFC or other IANA reference document backs the assignment. The identical entry is dual-registered on 144/tcp, with the same description, assignee, and blank reference, and neither the registration date nor the modification date columns are populated in the registry, so no allocation date can be reported. Beyond the bare registry label, no verifiable real-world software, protocol specification, or vendor documentation could be located for "uma" in this research pass; secondary port-lookup sites simply mirror the IANA name without adding substantive detail. One low-authority secondary source informally pairs the port with Sun's long-discontinued NeWS windowing system, an old piece of port-numbering folklore that is not reflected in the current IANA registry and is not corroborated by any primary source, so it is reported here only as unverified folklore. No CVEs, exploits, or malware families tied to 144/udp were found in this pass, and the port does not appear in commonly referenced well-known-ports tables, consistent with rare real-world use.

Primary use

no verifiable real-world software or protocol implementation identified beyond the bare IANA label; secondary port-database mirrors restate the name with no spec or vendor docs

[Unknown] — http://www.t1shopper.com/tools/port-number/144/; https://www.adminsub.net/tcp-udp-port-finder/uma

Other/unofficial uses

one low-authority secondary source informally links the port to Sun's discontinued NeWS windowing system ("news and UMA"); this is unverified folklore, absent from the current IANA registry and not corroborated by any primary source

Security implications

no CVEs, exploits, or malware families specifically tied to 144/udp found in this pass; a low-authority automated checker reports no current virus/Trojan association (generic boilerplate, not a documented incident); port absent from Wikipedia's well-known-ports table, consistent with obscure/rare use

Unknown — no evidence of common deployment found in this pass

Analyst note
Sparse, low-confidence entry beyond the core IANA registration; treat the NeWS folklore claim as unverified and do not present it as fact.
