I heard that there is hidden mining. What does it mean?
Hidden is called mining, which uses other people's resources, for example, launching mining by employees on corporate servers, or introducing code for mining into viruses and trojans.
There is a very interesting mechanism for hidden mining. I don’t remember exactly everything, but maybe someone will tell.
When installing the torrent client μTorrent (version 3.4.2 build 28913 and later), it is proposed to install an additional program EpicScale, which allows you to use computer resources during idle time for distributed computing. Representatives of μTorrent assure that the EpicScale network is currently used for cryptocurrency mining (without specifying the name), part of the funds received go to finance the company, and part - to charity. According to a number of publications, EpicScale is mining bitcoins. Other publications report mining Litecoin.
Wow! I didn’t know this. But it's like a virus, it turns out.
