Some dickhead was talking shit over a game then my entire wifi network shutdown? Thankfully called my cousin who’s pretty techy and he logged into my wifi login and said he “changed my dns” not sure what that meant but it’s working now. Severely un educated in the topic and I’m aware it probabaly won’t go past them fucking with my network but could any explain how they did that/ how to be preventative for it. If my cousin didn’t help woulda most likely been done but not sure. Appreciate any feedback
You didn’t get doxxed, that’s something different. That’s when your private info gets stolen and exposed to the public in an attempt to damage your image (as an example)
I think this was a denial of service attempt where the person sent a large number of packets to your public router to overwhelm the hardware for a few mins. It’s unlikely that they have the money or resources to sustain this attack though.
Given they may know your public IP or router’s DNS name, make sure you don’t have remote management enabled, change default password and maybe (if available) turn on DOS protection and disable ping response from WAN.
