Antminer S3 Being used to Access Websites

[mswells]

I have an Antminer S3, hooked up to an AP which connects to my router wirelessly.
I am seeing someone access the Antminer IP, and can see various websites being accessed
in my Router Logfiles:

How do I stop this unauthorized access....even when everything has been password protected?

[joesmoe2012]

Probably should reset your antminer and then immediately set a strong root password instead of the default.

I think it's virus in your computer.Scan whole computer.Or router hacked if it has default psw.

Make sure you do not have default name/password on router.  After that make sure your router has some sort of firewall up keeping the devices connected to it from being accessed from outside from the internet.  And finally change your S3 password just as a extra precaution.

With all of that it should keep it from being accessed on the internet.   Which should stop this issue.  The good news is with them using it to access websites and not change pool's it does not look like who ever did it knew what it was.  

If they really did a number on it and it keeps surfing websites then look into reloading the firmware.  But I think the above chances are will stop it without this step being needed.

I assume that your S3 is still mining using the pool that you want, with the credentials you want? The classic attack on a miner is to just point it at a different pool and let it coniynue to mine, for somebody other than the owner.

I changed the default password, and all is well now....but I am still confused how they were
using it to connect to websites with it.

On the S3's it has a beagle bone black as a controller board.  If you ssh into it then you have access to a lot of commands that would not be there via gui. Most likely someone was ssh'ed into it I would guess from reading.   But since they did not change pool's I have a feeling they did not know what they had access to.

But default passwords especially on routers are a bad idea in general.  Glad it stopped now.
