Worst attack ive ever received in my life. Full access to all devices, screens, webcams and they restreamed everything on a russian site.
Apparently theres a huge security issuemwith the modem im using (dpc 3925) that alows attackers to change the dns without the user noticing it.
Anyways I got two questions. How to block everything related to this address and IP:
I already blocked it on access restrictions, is that enough?
Second question: How can I set up authoritative DNS? Asking because even if I chekc the “Use customs dns servers” box, Im still getting the ISPs servers.
How can I block port 53 on the wan side so the router completely ignores the DNS provided by the modem?
