On a side note regarding security:

My mining rig is set up just to mine (Windows + JPC wallet + ccminer and not much else). I checked my router logs recently and found a lot of attacks. Some activity comes from University IT Departments, which routinely map open ports on the net. BUT most of the activity came from South Korea, Ukraine and here's the surprise: I had some attempted LAN access from 23.21.204.34:58679. Yep, miningpoolhub.com. Why would they be trying to access my ports? I hadn't visited them for weeks.
