I am fighting with my network provider.
If I have router with LTE GSM Card inside, is it possible for router malware to send text messages from it? Or has it ever been done? They say I subscribed to some paid services, which they allowed for unknown reasons.
I heard about using routers for DDoS attack or for reconaissance (Chameleon). Texting seems extremely challenging and hacker would probably go for easier target - mobile phones? Or maybe it would be easier to subscribe to paid services by spoofed SMS?
What operating system is there in TL-MR 3420? Busybox? Toybox? I found that you can install OpenWrt. What is there by default?
