Kun.exe – Really high CPU as well as GPU usage
Besides CPU utilization, some of the coin miners additionally utilize GPU power for their operations. In that situation, you will likely struggle also to see the mouse cursor moving – GPU is often used on 100%. It is not as important as processor for system work, so Kun.exe coin miner viruses do not waste time on trifles and utilize all of it. It often may cause bad results.
Shortly about cryptocurrency mining
Cryptocurrency mining term means the action of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this operation takes a lot of calculations, a high-end desktop is needed. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of video cards to conduct their activity effectively. Such systems are not usable for “normal” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

All these changes shall be gone back to the original in the process of computer recovery.
Hardware effects of coin miner activity
Besides decreasing your PC’s performance, performing at peak level for a long period of time may trigger damage to your device and raise power bills. Hardware elements are designed to easily deal with high load, but they can do so only in case when they are in a good shape.
Compact and covered CPU fan is quite hard to crack. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily cracked if touched while spinning, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Kun.exe malware can easily lead to GPU failure3. GPUs are also prone to have very fast wearing when used for crypto mining. It is surely an unwanted case when the performance of your video card plunges 20-30% only after 1-2 weeks of being exploited in such a way.
How did I get Kun.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 one of the most prevalent malevolent programs through “severe” malware. Adware often acts as a carrier for Kun.exe malware infiltration: it shows 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. But the statistics say that about 30% of all viruses spread with the malevolent banners are coin miners – and Kun.exe is just among them.4
The example of malicious banners you can see in the Internet
One more way you could get this thing on your computer is by downloading it from the untrustworthy site as a part of a program. Users who spread hacked variants of popular programs (which do not need the license key) have small chances to earn money. Therefore, there is a very big lure to include malware to the final package of the hacked application and acquire a coin for every setup. Prior to criticizing these guys for hacking and also malware distribution, ask yourself – is it okay to avoid purchasing the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much bigger sum for antivirus program as well as new parts for your PC.
