ABB AB, Cewe-Control — 00:0C:62 (MA-L)

OUI 00:0C:62 is a single MA-L block registered to "ABB AB, Cewe-Control" at Dept. LPCC/RE, Västerås, Sweden (SE 721 61). Cewe-Control is the soft-starter and motor-controller division of ABB, the Swiss-Swedish industrial-automation and power group. The business traces to a 1919 Swedish electrical-equipment maker (Charles Westerberg & Co AB, "Cewe") that was absorbed by ASEA around 1970 and folded into ABB after the 1988 ASEA–BBC merger. Devices behind this prefix are operational-technology (OT) hardware rather than IT or consumer gear: soft starters (PSR, PSE, PSTX families) and universal motor controllers (UMC line), many with Ethernet or fieldbus interfaces (Modbus RTU built in on PSE/PSTX; EtherNet/IP and Modbus TCP optional on UMC100.3 and newer) — which is why an Ethernet OUI was registered in the first place. An address bearing this prefix on a network should be read as an industrial-control asset and handled with OT segmentation in mind. As with every IEEE prefix, no allocation date is published: third-party MAC-lookup sites show "07 February 2003," but that is a database artifact, not an IEEE-authoritative fact, and is left null here. No CVE is tied to this OUI or to the soft-starter line specifically, though the broader ABB ICS portfolio has known advisories (e.g. CVE-2024-8036, CVE-2025-9574) that are relevant context for any sighting of these devices.

IEEE assignment

00:0C:62 → ABB AB, Cewe-Control, Västerås, SE [Confirmed] — IEEE MA-L (line 21199)

Registry / block size

MA-L (24-bit OUI); single prefix covering 00:0C:62:00:00:00 – 00:0C:62:FF:FF:FF (~16.8M addresses) [Confirmed] — the IEEE MA-L registry line 21199; https://hwaddress.com/company/abb-ab-cewe-control/. NOTE: IEEE's public OUI data publishes NO assignment/registration date; the "07 February 2003" shown on maclookup.app is a third-party database artifact, not an IEEE fact, and is recorded as Unknown.

Security context

no CVE is attributed to this OUI prefix or the soft-starter line specifically; the wider ABB ICS portfolio has OT advisories (CVE-2024-8036 insecure firmware update; CVE-2025-9574 unauthenticated web-server access on ALS-mini controllers) that are representative risk context for networked ABB industrial-control devices [Likely] — https://www.midnightblue.nl/blog/cve-2024-8036-abb-insecure-updates; https://windowsforum.com/threads/critical-cve-2025-9574-unauthenticated-access-in-abb-als-mini-controllers.386115/

Analyst note

treat any 00:0C:62 address as an industrial-control / OT asset; apply OT network segmentation and patch discipline rather than IT defaults.
