This malware doesn’t take note of the fact that you may need to make use of your desktop for other tasks – it will consistently use over 80% of your CPU power.

Besides CPU utilization, some of the coin miners additionally use GPU power for their tasks. In that case, you will probably struggle also to see the mouse cursor moving – GPU is often used on 100%.

Shortly about cryptocurrency mining

Crypto mining means the operation of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this action takes a lot of calculations, a very strong PC is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining farms are usually constructed of dozens of GPUs to conduct their activity effectively. Such systems are not usable for “classic” purposes, like gaming or browsing the Web. Crooks who gain money via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

All these adjustments shall be gone back to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides slowing down your PC, performing at peak level for a long period of time may cause damage to your machine as well as increase power costs. PC elements are created to easily get along with high load, but they can do so only when they are in a good shape.

    Small and covered processor cooling system is hard to broke. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily broke if affected while spinning, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the very high load caused by Wmic.exe miner can easily lead to graphic card failure3. GPUs are also tend to have very fast wearing when utilized for cryptocurrency mining. It is likely a bad situation when the performance of your GPU plunges 20-30% just after several weeks of being exploited in such a way.

    How did I get Wmic.exe coin miner virus?

    Coin miners are spread through different ways, but their main sources are malicious banners and programs from dubious sources

    Coin miners are the most prevalent malicious programs through “serious” malware. Adware sometimes acts as a carrier for Wmic.exe malware infiltration: it demonstrates you the banners, which contain a link to malware downloading. Yes, this abstract “malware” may belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics show that around 30% of all viruses spread through the malevolent banners are coin miners – and Wmic.exe is right one of them.4

    The example of malicious banners you can see in the Internet

    An additional way you could get this item on your PC is by downloading it from the unreliable website as a part of a program. Users that spread hacked versions of popular programs (which do not need the license key) have small chances to earn money. Thus, there is a very big lure to add in malware to the final package of the hacked application and acquire a coin for each setup. Before blaming these guys for hacking and also malware distribution, ask yourself – is it okay to avoid buying the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much bigger figure for antivirus program and new parts for your computer.
