removal by Alice Woods - - | Type: Ransomware

WannaCash is a cryptovirus which encodes data and demands to transfer the ransom to the Yandex wallet

WANNACASH virusWannaCash ransomware is the threat that demands money in the message that shows up as a text file. WannaCash ransomware is the Russian-speakers targeting threat that manages to encode files, so the ransom can be demanded from victims. It encrypts files using encryption algorithms and change the desktop wallpaper, changes text file on the desktop. The victimized files are encrypted with AES 256 algorithm and users are demanded to pay 4999 Roubles for the WannaCash decryption software that criminals allegedly have. Additionally, the payment must be transferred to Yandex[1] wallet which is one of the biggest electronic payment platforms in Russia.

However, our security researchers note that there are alternative ways how you can recover files encrypted by WannaCash virus without paying the ransom. The text file как расшифровать файлы.txt contains various scary claims, so it may seem that the best option is paying. However, we cannot stress enough how dangerous can Russian hackers get. Especially, when this threat has already released a few major versions. The most recent one, WANNACASH NCOV ransomware was released into the wild in March 2020, almost two years after the initial release of the original version.

It now uses double the encryption because relies on AES and RSA method mix and delivers the same Как расшифровать файлы.txt file as the money-demanding ransom note. This variant uses the pattern of extensions and renames files with Файл зашифрован. Пиши. Почта clubnika@elude.in [number].WANNACASH NCOV v310320 marker, according to the report from virus researcher.[2] Even though, this family uses the Russian language, there is still a possibility that malware occurs on devices in various countries all over the world.

  • .doc; .docx; .xls; .xlsx; .xlst; .ppt; .pptx; .rtf; .pub; .pps; .ppsm; .pot; .pages;
  • .indd; .odt; .ods; .pdf; .zip; .rar; .7z; .jpg; .png;

The ransom note by WannaCash virus is dropped after a successful data encryption[3]. People are asked to pay 4999 RUB for WannaCash decryption software. Additionally, they are urged to do so as the criminals claim that there is not much time left. Otherwise, random data will be deleted after every 10 minutes. However, people should not fall for these deceptive promises.  WannaCash ransomware illustrationWannaCash is a file-encrypting virus which encrypts data with AES 256 cipher and demands to transfer 4999 RUB to Yandex wallet.

WannaCash ransomware virus comes back in 2020

WANNACASH NCOV ransomware virus came out in March 2020, when the world was paralyzed and in lockdown due to the Coronavirus pandemic, but many people try to take advantage of such a situation, especially malicious actors. This is not the first version after the initial WannaCash, but other variants only carried the initial code and were released back in 2018, mainly.

Throughout those years ransom note evolved to a normal text file with a message about encryption, but all the other features remained the same. What comes different with WANNACASH NCOV ransomware?

First, WANNACASH NCOV ransomware adds a lengthy file marker to encrypted files and runs destructive processes in the background to avoid detections and quick virus removal. As for encryption, it is still the main purpose of the virus, but this particular version relies on AES and RSA encryption algorithm mix that ensures complete changes in the original coding of your common files. 

However, all these changes affect the WANNACASH NCOV ransomware removal as well. As always, ransomware creators prefer emails for contacting them, but writing via clubnika@elude.in, clubnika@cock.li is never recommended. There are too many incidents when paying victims are left with unrecovered and damaged files. You better remove malware with AV tools.[4]  WANNACASH NCOV ransomwareThe ransom note that is the most recent that WANNACASH NCOV ransomware victims received in the Как расшифровать файлы.txt file(original language):

У ВАС есть ровно 7 дней на связь со мной. 09.04.2020 числа в расшифровке ВАМ будет отказано,а ВАШ  ключ дешифровки в автоматическом порядке удален. Я предупредил.

* Крайне не рекомендую обращаться за помощью на форумы антивирусных компаний. Только лишь потеряете время на ожидание отрицательного ответа.

Spam email attachments might hide the payload of ransomware

Even though the inbox might seem like a safe place, criminals distribute infected emails to spread cyber threats. Usually, the malware comes as an attachment which might mimic innocent documents, such as invoices or shopping receipts. Users who fail to identify an infection and open the attachment infiltrate a file-encrypting virus on their systems. 

Likewise, it is vital to monitor your inbox. Always be cautious that cybercriminals disguise as well-known companies or brands to trick novice PC users. Never open any suspicious attachments and if you have any doubts about the legitimacy of the letter, contact the company directly and ask for confirmation. 

Look out for any red flags and make sure to delete any emails that:

  • state about financial information;
  • include files attached or hyperlinks in the notification itself;
  • are send from unknown senders;
  • contains grammar mistakes or typos;
  • ask for additional content agreements or offers to enable macros.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove WannaCash 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 WannaCash, you can use several methods to restore them:

Retrieve corrupted files with Data Recovery Pro

This professional software was primarily developed to recover deleted or damaged data after the system crash. However, experts note that it might be useful in case of ransomware as well.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by WannaCash ransomware;
  • Restore them.

Get back data with Windows Previous Versions Feature

The first thing to do before using this option is to check whether the System Restore function was enabled before.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Using ShadowExplorer to recover encrypted files

ShadowExplorer software is an excellent method to recover compromised data if the ransomware hasn't deleted Shadow Volume Copies from the 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.

Professional WannaCash decryptor is still in development.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from WannaCash and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
