462
Summary
- // if you see it open
- No CVE specific to port 462 is recorded in the NVD as of an August 2026 search. AuditMyPC's port-462 page did not render a retrievable verdict line, so no malware/trojan association can be confirmed or ruled out from that source. No documented legitimate deployment pattern was found.
- // analyst note
- An open port 462/tcp has no established legitimate use case documented; treat an observed listener as worth investigating rather than assuming a known service.
About port 462/tcp.
Port 462/tcp is registered with IANA as datasurfsrvsec ("DataRampSrvSec"); no independent research identifies what actually runs on it today, so it should be treated as internal/legacy rather than something expected to face the public internet.
The IANA Service Name and Transport Protocol Port Number Registry lists 462 as dual-registered on both TCP and UDP under the same service name, assigned to Diane Downie, with a blank Reference field — no RFC or other specification is cited for the protocol. The registry entry carries no registration or modification date.
Beyond the bare registry listing, no credible source ties 462/tcp to a specific product, vendor, or protocol in active use. General port-lookup mirrors reproduce only the IANA name and description without adding independent detail, and no forum or vendor documentation surfaced describing real-world traffic on this port.

Primary use
Unknown — IANA registry gives only the service name and a blank reference; no protocol specification or independent application attribution was found
Other/unofficial uses
Unknown — no community-sourced sighting of a specific application or vendor product was found in an August 2026 search [Unknown]
Security implications
no port-462-specific CVE found in NVD as of August 2026; AuditMyPC verdict page not retrievable so no malware association confirmed either way
Typically seen on
Unknown — no deployment context identified

About port 462/udp.
Port 462/udp is registered with IANA under the service name datasurfsrvsec ("DataRampSrvSec"), but no RFC, specification, or corroborated software documentation ties to that name, so the port cannot be attributed to a known legitimate service — treat any active listener here as anomalous and worth investigating rather than as routine traffic safe for internet exposure.
The IANA registry entry lists assignee/contact Diane Downie and a blank Reference field and a blank Registration Date field — no spec was ever attached to the assignment. The same service name and description are dual-registered on 462/tcp, an identical, equally undocumented pairing.
Measured prevalence from the repo's nmap-services artifact puts 462/udp at an open-frequency of approximately 0.00056 (about 0.056%), versus roughly 0.000025 (about 0.0025%) for the paired 462/tcp entry — both low but non-zero readings, not absences.
A targeted web search for vendor docs, blog posts, or forum/support threads naming software that generates traffic on this port came back empty; port-aggregator sites only echo the bare IANA label rather than adding an independent sighting, so no application attribution is made here. No CVE, trojan, or malware family tied to 462/udp turned up in the NVD or in general trojan-port compilations checked as of an August 2026 search.

- Analyst note
- An open 462/udp cannot be attributed to any documented application — investigate rather than assume it is routine traffic.
