Brutal cryptocurrency mining malware crashes your PC when discovered | ZDNet

Several thousand computers on a botnet can mine cryptocurrencies much more effectively than a single computer can. In the case of a mining botnet, victims also foot the electricity bill, making installing miner applications on the computers of unsuspecting users a very lucrative business for hackers.

Note that a rank-and-file user can install a miner application intentionally, to mine cryptocurrency on their own.

Distinguishing legal mining from illegal activity is the challenge. Miner applications are identical; the difference is in the covert installation and operation of illegally acting applications. In most cases, a miner ends up on a computer with the help of a purpose-built malicious application, a so-called dropper whose chief function is to secretly install another application.

Droppers usually come under the guise of pirated versions of licensed products or activation key generators for them. Users look for this type of software on peer-to-peer networks and download it intentionally. The application can also come complete with services that ensure its autorun and configure its settings. For example, such services can suspend the miner when the user starts certain popular computer games.

Such services can also attempt to disable antivirus products, suspend the miner when a system monitoring tool is running, and restore the miner if the user tries to delete it. Let it do its thing. Hidden miners basically feed off your computer, like a parasite. On the flip side, you could install your own miner and mine cryptocurrency for yourself.

A Web miner is essentially a script hosted on a website. When a user visits the site, the script runs in the browser and starts mining cryptocurrency. In both cases, whoever installed the Web miner gets the money; those who created the miner earn a fee. The principal difference between Web miners and ordinary miners is that Web miners do not require the installation of any additional programs on the computer; everything happens directly in the browser window. But the computer slows down and the fan whirs — and the next electricity bill is a shock.
