Error ransomware comes to corrupt your files and demand a ransom

Error ransomware virus

Error virus is a typical ransomware that comes from CryptoMix (Revenge) crypto-ransomware family[1]. As its name suggests, the virus appends .ERROR extension to files after encrypting them and changing their names. Earlier versions of the virus used .CK, .CNC, .OGONIA, .ZERO, .ZAYKA and .MOLE file extensions to mark the corrupted files. Just like previous variants, the virus leaves _HELP_INSTRUCTION.txt file with instructions for the ransom payment.

Ransomware uses eleven RSA-1024 keys to corrupt the AES key that is used to encode[2] victim's data. This gives the virus a possibility to work in offline mode on the compromised system.

The style of the virus hasn’t changed as well as the contents of the ransom note. It provides three email addresses for the victim so that one could contact the attackers immediately:

Hello!

Attention! All your data was encrypted!
For specific information, please send us an email with your ID number:

error01@msgden.com
error02@webmeetme.com
errorout@protonmail.com

We will help you as soon as possible!

[victim’s identification number (ID)]

We do not encourage you to write to any of the provided emails because the cyber criminals will simply reply with a ransom demand. They might ask you to pay a sum worth $500-$2000 in Bitcoins (cryptocurrency). Such payment method helps criminals cash out the collected ransoms without being identified.

While it is not recommended to pay a ransom to ransomware developers, we also have to point out that it is hardly possible to restore files without having the decryption key (hidden in cyber criminals’ servers). Sadly, only a data backup can efficiently help you to restore your files.

If you haven’t created it in the past, then it will be very hard or nearly impossible to restore your .error file extension data back to normal. You can use one of the provided methods (find them below the article) to recover some of the corrupted records.

Before you attempt to remove Error ransomware virus, we strongly suggest restarting your computer in a safe mode with networking and updating your security software first. This way, it will recognize this new Cryptomix version and delete it without any problems.

You can find in-detail CryptoMix Error ransomware removal instructions right below the article. In case you do not have a security software to use at the moment, consider installing a program recommended by our team.

Distribution of the disastrous crypto-ransomware virus

CryptoMix (Revenge) ransomware variants were noticed spreading via malicious spam[3], although cyber security researchers also revealed another distribution channel used to infect computers with this virus – RIG exploit kit.

It appears that scammers are infecting websites and inserting a malicious JavaScript code into them. If the victim happens to enter such website, the exploit kit scans victim’s computer for vulnerabilities and uses them to execute the ransomware on the system.

To prevent this virus’ attack, you must have an up-to-date anti-malware software as well as a copy of your files stored on an external data storage device (USB or portable hard drive). We must add that it is essential to enable automatic software updates so that you wouldn’t have to update each program manually and always have the latest and the most secure software versions on your system.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove ERROR from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by ERROR, you can use several methods to restore them:

Restore data using Volume Shadow Copies

In some cases, victims successfully recover their files from Volume Shadow Copies that Windows creates automatically. However, ransomware often tries to corrupt these files. We strongly recommend trying ShadowExplorer to see if there are any VSS left on your system.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

No .ERROR file extension recovery tools are available at the moment

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from ERROR and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
