What is Unrealcefsubprocess.exe process?
It is possible for malicious actors to abuse the UnrealCEFSubProcess.exe process for cryptojacking
Since UnrealCEFSubProcess.exe is a legitimate process associated with the Unreal Engine, it can be targeted by attackers who modify or replace the original executable with a malicious version. In such cases, the modified UnrealCEFSubProcess.exe process would run in the background and utilize the computer’s processing power and resources to mine cryptocurrencies for the benefit of the attacker.
To avoid falling victim to such malware, it is crucial to ensure that your system is protected with up-to-date antivirus software and that you only download software or executable files from trusted sources. Regularly scanning your system for malware and keeping all software, including the Unreal Engine, updated with the latest security patches can also help mitigate the risk of unauthorized cryptocurrency mining or other malicious activities.
Besides CPU utilization, some of the coin miners also make use of GPU power for their tasks. In that case, you will probably struggle even to see the mouse cursor moving – GPU is often used on 100%. It is not as important as processor for system work, so Unrealcefsubprocess.exe coin miner viruses don’t waste time on trifles and use it all. It sometimes may cause unhappy consequences.
Shortly about cryptocurrency mining
Crypto mining is a term that means the action of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this operation takes a lot of calculations, a strong PC is required. Exactly, the video card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of dozens of GPUs to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ hardware instead, even if they are used for the regular activity.1

If you check the HOSTS file, you will likely see a number of new entries – they are added by this coin miner to connect your system to a malicious mining network. All these adjustments are about to be thrown 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 power for a long period of time can cause damage to your device as well as raise power expenses. Hardware elements are designed to easily get along with high load, but they are good with it only when they are in a good shape.
Compact and covered processor fan is hard to damage. Meanwhile, GPUs have large and easy-to-access cooling fans. You can accidentally damage them by touching them while they’re running. Such a pity occasion may happen much before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Unrealcefsubprocess.exe miner can easily lead to graphic processing unit failure2. Graphic cards are also tend to have increased wearing when utilized for crypto mining. It is likely an unwanted situation when your GPU’s performance plunges 20-30% just after 1-2 weeks of being exploited in such a way.
How did I get Unrealcefsubprocess.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 common malicious programs among “severe” viruses. Adware frequently serves as a carrier for Unrealcefsubprocess.exe malware infiltration: it demonstrates you the banners, which include a link to malware downloading. Sure, this abstract “malware” may belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all malware spread with the malicious banners are coin miners – and Unrealcefsubprocess.exe is just with them.3
One more way you could get this thing on your PC is by downloading it from the dubious website as a part of a program. People that spread hacked variants of favored programs (which do not demand the license key) have small chances to make money. Therefore, there is a huge lure to include malware to the final package of the hacked app and acquire a coin for each installation. Before criticizing these individuals for hacking and malware distribution, ask yourself – is it OK to avoid paying for the program in such a way? It is much cheaper to pay $20-$30 at once than to pay a much greater sum for antivirus software as well as new parts for your computer.
