Besides CPU usage, some of the coin miners additionally use GPU power for their operations. In that instance, you will likely struggle also to see the mouse arrow moving – GPU is usually utilized on 100%.

Shortly about cryptocurrency mining

Crypto mining term means the activity 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 high-end PC is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of video cards to complete their task efficiently. Such systems are not usable for “general” 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

    “Visible” damage is not a solitary unpleasant activity coin miners perform to your system. Umxn.exe coin miner likewise deals damage to your operating system. To perform all malevolent operations successfully, it ruins the security features of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid detection. If you check the HOSTS file, you will likely see a number of new notes – they are added by this trojan miner to connect your system to a malicious cryptomining network. All these changes are about to be reverted to the original in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, performing at peak power for long times can trigger damage to your machine as well as increase power costs. Hardware elements are designed to easily deal with high load, but they are good with it only when they are in a good shape.

    Compact and covered processor fan is quite hard to damage. Meanwhile, GPUs have large and easy-to-access rotors, which can be easily broke if affected while running, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Umxn.exe malware can easily lead to graphic card failure3. GPUs are also prone to have fast wearing when utilized for cryptocurrency mining. It is surely an unwanted case when your GPU’s performance plunges 20-30% just after several weeks of being exploited in such a way.

    How did I get Umxn.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 widespread malevolent programs among “severe” viruses. Adware sometimes acts as a carrier for Umxn.exe malware injection: it demonstrates you the banners, which contain a link to malware downloading. Sure, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all viruses spread with the malevolent banners are coin miners – and Umxn.exe is just one of them.4

    The example of malicious banners you can see in the Internet

    Another way you could get this thing on your PC is by downloading it from the dubious website as a part of a program. Users that spread hacked variants of popular programs (which do not require the license key) have small chances to earn money. Hence, there is a huge temptation to add in malware to the final package of the hacked app and receive a coin for each setup. Prior to blaming these people for hacking and also malware distribution, ask yourself – is it OK to avoid paying for the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much greater figure for antivirus software as well as new parts for your desktop.
