Late reply, but you got something in your system (forget about your router or modem, those usually reboot at night , specially modems and they pull a whole new bin from the provider, so a hacker must hack it first and patch the firmware, and its not easy task ). There are many ways to get crap in your system, cracked stuff, free software, etc. Server admins know your public Ip address cuz they can ban you by many methods, user, Ip, etc, so anyone knowing your Ip can ddos. Besides that, you can have an $10000 antivirus , if it don't know the thread or recognize the behavior , it may let it do whatever it want. There are more ways to hack a system in your scenario regarding bf4, but I think none will do that for fun, unless you pissed someone that knows how to do it.
I'm going to lock this thread as it hasnt been active since 2022.
