I happened to have read a article about a botnet build on hacked modems
in China, https://blog.netlab.360.com/pink-en/ in this case, when
devices gets hacked, the only to "fix" is a replacement.
I’m surprised they didn’t at least update the kernel included on OP’s modem to a version that is still being maintained in the longterm…(4.4.y or later I believe?)
goes without saying but… old versions of the kernel are certainly way more prone to these attacks and 100% shouldn’t be included on hardware meant to be connected to the internet. (let alone send that connection to other devices and otherwise manage the network…)
