Avikus Co., Ltd holds the MA-L block 3C:CB:4D, registered to a Gangnam-gu, Seoul address (11F, 70, Nonhyeon-ro 85-gil). Avikus is the maritime autonomous-navigation arm of HD Hyundai (formerly Hyundai Heavy Industries Group, the world's largest shipbuilder); it was spun up around December 2020 / January 2021 as HD Hyundai's first in-house venture and is publicly branded "HD Hyundai Avikus." Its flagship product family is HiNAS (Hyundai Intelligent Navigation Assistant System): HiNAS Navigation fuses radar, AIS, and electro-optical/infrared camera inputs into an augmented-reality obstacle display; HiNAS Control delivers Level 2 autonomous navigation (controlling heading and RPM, DNV type-approved); HiNAS SVM provides 360-degree surround-view berthing cameras; HiNAS Cloud handles fleet analytics. A consumer line, NeuBoat, targets leisure vessels. The systems are vessel-mounted on-board computing units, retrofit-installable aboard existing ships in roughly three days without dry-docking, and Avikus completed what it claims as the world's first transoceanic autonomous voyage of a large merchant ship in June 2022. The 3C:CB:4D OUI is consistent with networked on-board hardware embedded in HiNAS units, though Avikus does not publicly disclose the specific NIC chipset or computing module behind the registration. No CVEs or security advisories attributed to Avikus or HiNAS were found in public sources — an absence of reporting, not a clean bill of health. As always for an OUI: IEEE publishes no registration dates, so any "date registered" shown by third-party MAC lookup tools is a database artifact, not an IEEE fact.
- IEEE assignment
- 3C:CB:4D → Avikus Co., Ltd, registered Seoul, KR [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv, cached MA-L snapshot)
- Registry / block size
- MA-L (24-bit OUI; 2^24 addresses) [Confirmed] — IEEE MA-L. Single hit in oui.csv; not present in mam.csv (MA-M) or oui36.csv (MA-S). NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

- OUI hardware specifics
- Unknown — Avikus does not publicly disclose the NIC chipset, computing module, or Ethernet/Wi-Fi controller behind 3C:CB:4D [Unknown] — no public source located
- Security context
- no CVEs or published vulnerabilities attributed to Avikus or HiNAS were found in publicly indexed sources. Network-connected sensor-fusion units aboard vessels carry general OT/IT-convergence risk, but no Avikus-specific incident, CVE, or advisory was located. Absence of reporting, not a clean bill of health. [Unknown] — https://nvd.nist.gov/vuln (no matching entries at time of research)
- Analyst note
- a 3C:CB:4D address on a globally-administered MAC identifies Avikus/HiNAS maritime hardware; useful for OT asset classification on vessel networks. Exact device model is not OUI-derivable since Avikus does not disclose the underlying component.
