“Suspicious Surfing Behavior More Information
As soon as it find itself on your computer system this program’s primary purpose is to inject JavaScript. This JavaScript aims to attack your CPU and GPU and use them in order to perform the so-called hashing operation, which is basically the mining procedure for the Monero cryptocurrency. Monero usually overloads the GPU (VideoCard) of the computers in which it is mined, since it’s most often used mining algorithm is called “Cryptonight” and it is used by many legitimate miners as well. What the first activity of this JavaScript is, is to connect your computer to various different types of CryptoCurrency mining pools – virtual places where the infected computers combine mining power in order to generate more of the Monero tokens which the miner hashes for.
