removal by Olivia Morelli - - | Type: Malware

CoinCube – a malicious program that mines cryptocurrency illegally

Coincube miner website

CoinCube Miner is a malicious script that can be used on any website to mine cryptocurrency.[1] The problem with this miner[2] is that it is widely used by cyber criminals who spread it with the help of potentially unwanted programs (PUP) that redirect to compromised cryptocurrency mining websites.

Summary
Name CoinCube
Type Cryptocurrency miner
Distribution FileTour adware and other potentially unwanted apps
Symptoms Redirects to questionable websites, aggressive ads, some computer processes using lots of CPU
Affected browser Google Chrome, but others might not be immune too
 To uninstall CoinCube, install Reimage and run a full system scan

In most cases, CoinCube virus spreads with the help of adware called FileTour. This type of PUP is designed to alter browser’s settings in order to redirect to compromised sites and display aggressive ads while you’re browsing the internet. Malware mostly targets Google Chrome; however, other browsers might be affected as well.

When CoinCube malware infiltrates the system, it creates a Windows autorun in order to force Chrome to redirect to mining website. This trick allows opening the browser in the background, meaning that you cannot see such activity. However, you can notice that browsing sessions became sluggish, browser constantly freezes or crashes.

However, the easiest way to spot CoinCube Miner is to open Windows Task Manager and look through running processes. The miner uses up to 100% computer’s CPU, so if you some of the processes eating up so much computer resources, it must be a miner.

The main danger here is that high CPU usage leads to computer overheat problem. Therefore, your PC or some parts of it (e.g., motherboard) might get physically damaged. Hence, it may lead to huge problems, such as data loss.

Therefore, if your laptop seems too hot than normal and fans are running like crazy, you should check the processes running on your PC. Typically, this miner hides under the name of CoinCube Miner2 or chrome.exe processes. Obviously, you have to stop them from running.

However, it’s not enough to stop them in order to remove CoinCube Miner. After the system reboot, the miner launches its activity again. Therefore, you need to find and uninstall adware and other PUPs that help the miner to do the job.

For full CoinCube removal, we highly recommend employing anti-malware program, like Reimage. It’s the easiest way to find and identify potentially malicious apps and clean the system. After that, you can also reset the browser in order to make sure that adware-related components are gone for good.

Cryptocurrency miner might get into the machine unnoticed

As we have already told, redirects to mining website begin after infiltration of FileTour adware. This potentially unwanted app was noticed actively being spread in freeware and shareware bundles. This tricky software marketing method allows getting into computers unnoticed.

The majority of users do not pay proper attention to freeware installation procedure, a research team from Bedynet.ru[3] say. Most of the people rely on Standard or Recommended settings to install the desired program quickly. However, these settings have some major issue.

Recommended setup does not reveal what additional programs are spreading in the same software package. Hence, unwanted apps can enter the system without your consent. Indeed, it seems an unfair activity, but it’s entirely legit.

However, you can protect yourself from PUPs and their negative features. All you need to do is to use Custom or Advanced installation settings, and carefully follow each of the steps. If there are any “additional downloads,” you should opt them out.

To remove CoinCube miner from the machine, you should not only stop suspicious processes running on the computer, but uninstall malware-related components from it too. We do not recommend doing it manually, because it is most likely to end up with a failure.
