Wuxi Xinjie Electric Co., Ltd — B8:A7:5E (MA-L)

The prefix B8:A7:5E resolves to Wuxi Xinjie Electric Co., Ltd, an industrial automation manufacturer in the Hu Tai Industrial Park, Binhu District, Wuxi, Jiangsu, China. The company self-brands in English as "Xinje" (en.xinje.com); "Xinjie" is an alternate romanisation that surfaces in some third-party MAC registries and in the IEEE record itself, so both spellings point at the same registrant. This is a single MA-L allocation (~16.7M addresses), not a consolidated multi-block vendor. What matters operationally is what the hardware is: Xinje builds OT/ICS equipment — programmable logic controllers (PLC), human-machine interface (HMI) panels, servo drives, frequency inverters, motion controllers, IoT gateways, and EtherCAT switches and slave devices — so a B8:A7:5E address on a network almost certainly belongs to an industrial controller, not a consumer device, and its appearance in an IT-only segment warrants a look. The company is an EtherCAT Technology Group member and ships Ethernet/Modbus-TCP add-on modules for its XC/XD PLC families. There is a material security caveat: CISA advisory ICSA-23-024-01 (24 Jan 2026 [year per advisory page; original 2023]) documents two chained, locally/network-adjacent vulnerabilities in the XINJE XD/E Series PLC Program Tool (v3.5.1 and prior) — CVE-2021-34605 (zip-slip path traversal) and CVE-2021-34606 (DLL search-path hijack), each CVSS v3.1 7.3 (HIGH) — which together allow arbitrary code execution on an engineering workstation that opens a malicious project file or syncs from a compromised PLC. No vendor patch was publicly confirmed at advisory time, so any workstation that programs Xinje PLCs should be assessed for exposure, and the devices kept network-segmented and off the public internet.

IEEE assignment

B8:A7:5E → Wuxi Xinjie Electric Co.,Ltd (registrant spelling "Xinjie"; company self-brands "Xinje") [Confirmed] — IEEE MA-L (line 104); corroborated maclookup.app, udger.com

Registry / block size

MA-L (24-bit OUI; ~16.7M addresses); single block [Confirmed] — IEEE MA-L / maclookup.app

HQ / country

No. 9 Liu Tang Road, Hu Tai Industrial Park, Binhu District, Wuxi, Jiangsu 320200, CN [Confirmed] — IEEE MA-L (line 104), udger.com

Registration date

Unknown — IEEE publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address). A third-party tool (maclookup.app) shows "April 2023" but that is a database artifact, not an IEEE fact. [Unknown] — see no_ieee_date_note

Security note

CISA ICSA-23-024-01 covers CVE-2021-34605 (zip-slip path traversal, CWE-23, CVSS v3.1 7.3 HIGH) and CVE-2021-34606 (uncontrolled search-path / DLL hijack, CVSS v3.1 7.3 HIGH) in the XINJE XD/E Series PLC Program Tool ≤ v3.5.1 — chained to achieve arbitrary code execution via a malicious project file or a compromised PLC. Disclosed by Claroty Team82 (May 2022, extended coordinated disclosure); no vendor patch publicly confirmed at advisory time.

Name disambiguation

B8:A7:5E is Wuxi Xinjie/Xinje Electric. NOT the same as "SHENZHEN JIAXINJIE ELECTRON CO.,LTD" (E0:3C:5B, MA-L) or "Suzhou Ruixinjie Information Technology Co.,Ltd" (MA-M, 50:62:55:5x) — different companies that merely share the "xinjie" syllable.

Analyst note

A B8:A7:5E MAC indicates an Xinje industrial device — most likely a PLC, HMI, IoT gateway, or EtherCAT controller in an OT environment. Presence in an IT/enterprise-only segment warrants investigation. Given the disclosed chained RCE in the XD/E programming tool with no confirmed patch, any engineering workstation connected to Xinje PLCs should be assessed; these devices should be segmented and never internet-facing.
