ABIsystems Co., LTD — A4:01:30 (MA-L)
Summary
- // what this is
- ABIsystems is registered to MAC prefix
A4:01:30in the IEEE OUI database. When a device's MAC address begins withA4:01:30, that block was registered by ABIsystems — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Devices carrying A4:01:30 are most plausibly industrial ZigBee building/lighting-automation hardware (gateways, dimming converters), not consumer networking gear. Company operating status and any vulnerability history beyond this light pass remain unconfirmed.
About this vendor.
ABIsystems Co., LTD is a small South Korean building-automation vendor holding a single IEEE MA-L block, A4:01:30, registered to an address in the ACE Techno Tower complex in Guro-dong, Seoul. Unlike single-OUI registrants that turn out to be shell filings with no discoverable products, ABIsystems has a paper trail: FCC grantee code 2AFXY covers two ZigBee-based devices submitted in September 2015 — a ZigBee-to-LON gateway (model AL-LZ100-NM) and a ZigBee dimming converter (model AL-DX310-NZ) — and the FCC filing address matches the OUI registry address closely enough to confirm it's the same company. The AL-LZ100-NM's user manual describes a 2.4GHz ZigBee radio bridged to a 78Kbps two-wire LON (Local Operating Network) bus, powered from 24V DC, consistent with a building/lighting-automation gateway rather than a general-purpose consumer network device. No CVEs, botnet associations, or default-credential advisories surfaced in this pass, though that absence isn't proof of a clean record given how little English-language coverage exists for this vendor. Devices carrying this OUI should be treated as industrial/IoT lighting-control hardware, not desktop or mobile networking gear.
