EW1200G-PRO router hacked/flashed

Hi,

We have hundreds of the EW1200G-Pro, we use them for our fibre customers, it seems almost 100+ routers have been hacked either by dns port 53 or remote manament port 80, the routeres firmwares has been removed, it cant reset, doesnt boot.

can you guys make it so that the remote management port can be adjusted so it can be filtered without affecting customers traffic? maybe a custom port range or a port like 8085? also these routers are completely exposed without authentication for programs like MQTT Explorer using port 1883, this reveals a lot of private customer info, like customer connected devices, pppoe information, wifi name and password information

could you guys assist me to tell me if its possible to reflash the firmware for these routers and if you are planning on having more secured firmware? also possibly adding a custom port range for the remote management option?

Dear sir,
May I know your network topology?and 100+ routers have been hacked can you take a screenshot of that,What is the phenomenon of being hacked?
and the SN of the device

Dear sir,

Hi,

Do you want a video of all hundred devices or just one to see what happens?

We have not changed any configuration on the clients router at that stage, there was a flood of DNS port 53 requests to our network and almost all these reyee routers stopped worked, we are using basic config for the reyee routers i can attach a config file of a currently replaced reyee router if that would help?
