Browser-based Cryptocurrency Mining Ramping Up
by Vertek Labs
How does it affect me or my users?
The user is not infected with anything, but they may notice a significant performance impact just by simply visiting a website (or an ad) that calls and loads a mining script. Below is a test that our labs teamed performed by browsing to a website that had the coin-hive mining library embedded. As you can see, CPU resources spiked to 100% until the page was closed.
What can you do about it?
We have signatures to detect it and we’ll make our clients aware of the activity. If you have the capability to block or blacklist domains, we are recommending that you block the following.
By blocking these domains (known at the time of this writing), your users won’t be able to load the mining scripts.
