Crypto mining is grabbing headlines constantly. Sometimes it is for all of the wrong reasons. There is a huge online threat that is less publicized, and that is hackers stealing CPU (and/or GPU) power to mine cryptocurrency.
There are cryptocurrency mining web sites that use javascript and script injections within browsers to generate revenue. Sadly, the target (you) never sees a cent of this currency, and is left with a massive decrease in processing power (sometimes complete failure of equipment).

flareDNS is now fully equipped with a blocklist specifically developed by the team at CybX Security LLC to block these potential threats, and will not allow any form of connection to such domain names, IP addresses or indeed websites.
