4G Systems GmbH & Co. KG (00:0E:56)

A MAC address starting with 00:0E:56 belongs to 4G Systems GmbH & Co. KG, a German mobile-connectivity hardware maker, and typically identifies a USB cellular modem or portable Wi-Fi hotspot router from the company's product line.

4G Systems GmbH & Co. KG is a Hamburg-based company founded in 2002 by Alexander Sator. Its current product catalog includes the XSStick series of USB mobile-broadband modems, the XSBox series of portable MiFi-style hotspot routers, and a digital-signage line marketed under the StretchedTV brand, distributed in Germany through resellers including Mobilcom-Debitel and Maxxim Data.

IEEE's registry lists a single MA-L assignment for this company, 00:0E:56, registered to an address on Jarrestrasse in Hamburg. A business-directory listing (Dun & Bradstreet) gives a different registered address in Köln; which one is current was not resolved, so both are noted rather than one being asserted as authoritative.

No CVE is recorded in the NVD for 4G Systems, XSStick, or XSBox devices as of a September 2026 search. Several low-authority router-default-credential sites document a default admin login on XSBox models, a pattern common across consumer MiFi routers generally rather than a vendor-specific disclosed vulnerability.
