5 stars based on 47 reviews

Cryptocurrency mining is an IT industry buzzword and a rapidly growing phenomenon. In doing so, these miners come up with more and more ingenious ways, not all of which are legal, to earn the coveted coins. We have written before about botnets and how hackers can turn your computer into a zombie and make it a part of a botnet. A network of such zombie computers can be used for a variety of purposes, including but not limited to cryptocurrency mining. 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 bitcoin miner bot net attacks 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.

Hackers distribute such applications as a service. They use Telegram channels devoted to online work opportunities; you might come across ads offering trial versions of such droppers for distributing a hidden miner. To give you an idea of the scale of this phenomenon: Our experts recently detected a botnet consisting of an estimated several thousand computers on which the Minergate miner was secretly installed.

Kaspersky Internet Security does not block or remove such applications by default; a user may have installed them on purpose.

Despite an increase in popularity over recent months amongst botnet operators, malware-powered Bitcoin mining brings little to no financial return, say experts. Security giant McAfee contends in its quarterly threat report PDF that commercial botnet controllers and malware packages have been adding cryptocurrency mining options to their list of services offered. The mining tools - offered alongside botnet task options such as spam runs or distributed denial of service DDoS attacks - put infected machines to use mining Bitcoin.

Unfortunately for the cybercrooks, however, it seems that a botnet-turned-mining rig doesn't actually make much money in real life.

McAfee found that the increasing difficulty of Bitcoin hashes, combined with the attrition rate from malware detections on infected machines, would make turning a profit from botnet mining nearly impossible. According to researcher estimates, a botnet controller attempting to mine Bitcoin with a 10, system network would initially see a net loss in operations and with increasing difficulty cycles productivity would plateau off without turning much of a profit.

That rate becomes even lower when mobile devices are added to the equation. Researchers note that with less powerful processors and limited battery life, mobile devices are ill-equipped to function as dedicated cryptocurrency mining tools, especially when this is done via covert malware infections. Researchers conclude, therefore, that botnet kingpins are better off avoiding the Bitcoin mining game and sticking with other techniques.

That would come as little relief, however, to owners of infected machines who will see their system performance and battery life take a hit whether or not the miner turns a profit.
