So I haven't logged into my Slingshot account in a while but after doing so today I've noticed that the data usage has gone up heaps in the last 4 months! I don't believe anyone in the house is using that much more data all of a sudden. Is there an easy way to track down whats using so much data or where do I start?

What kind of router do you have? Could be your router acting as an open DNS resolver.

Ensure your IP is not resolving by using this: http://openresolver.com/

If my math is correct, you've gone from a regular 300gb to an almost 4tb a month, which was sudden and it appears to be getting worse?

If you are clean and clear with the open resolver linked above, I'd be googling up some free network monitoring software to identify the computer or device that is generating the traffic.

Once identified, I'd unplug the device and confirm the traffic has stopped. The free software would hopefully do this for you.

From there I would make a decision on what to do with it. The only real decision for me would be how much to back up from it (I would be aiming for zero) before formatting it or throwing it out in the garage behind the box of bicycle parts.

You learn more as you go, you may find out that several devices are creating the traffic, I'd re-assess at each step to decide next course of action.

I'm such an idiot! When I switched to the RouterBOARD 962UiGS-5HacT2HnT I forgot to change any of the default firewall rules. Now its not resolving anymore and data use is back to normal with 15GB used in past 24 hours. Thank you for your suggestion!

Personally im well in the field of isps should block by default DNS outbound. Its already done for mail ports commonly

I think they should just do a simple open resolver check on your connection whenever a new PPP session is started. And then redirect to a walled garden page if one is detected.
