How to block Crypto Miner (javascript)

L3 Networker

This week I noticed a "CoinHive Javascript Detection" in the logs of our Palo Alto.

When reading on the subject I noticed that there are websites around that use Javascript to start mining Crypto coins on the users' computer.

Detailed description can be found here :

I noticed in the Palo Alto blog that : PANDB is able to block URLs hosting Coinhive JavaScript.

 

My question:

How does one actually block this?

When I visit for example https://coinhive.com/ and push the button "Start Mining" the CPU goes up to 100%.
