Wana Decrypt0r 2.0 .WNCRY File Virus (Restore Files)

This article is created to help you remove the .WNCRY Wana Decrypt0r 2.0 ransomware infection (new WannaCry variant) and restore files encrypted with the .WNCRY file extension.

A new ransomware, called Wana Decrypt0r 2.0 by malware hunters has been reported to encrypt files on the computers infected by it. The ransomware virus uses the .WNCRY file extension and it is basically reported to be a new version of the WannaCry also known as WCry family of ransomware viruses. The infection drops a ransom note, named @Please_Read_Me@.txt and changes the wallpaper as well as adds software with instructions for paying the ransom. In case you have become a victim of this ransomware infection, we strongly recommend to read the following article thoroughly.

Data Recovery Tool Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.

Update November 2017! WannaCry has stopped infecting since the malware researcher, known as @malwareTechBlog has found a kill-switch to it. The bad news is that the financial damage caused by this virus is still continuing to increase in magnitude.

.WNCRY Virus – How Does It Spread

Similar to the previous .wcry variant , this ransomware iteration may also use the very same methods to spread. They are connected with the usage of different types of tools used specifically to distribute malicious files and URLs without being detected:

  • The ETERNALBLUE and DOUBLEPULSARE Exploits leaked by the ShadowBrokers in a leak, called “Lost in Translation” which happened back in April 2017
  • Spamming software (spam bots, crawlers, etc)
  • Pre-configured list of e-mail addresses of potential victims to which spam mail may be sent.
  • Intermediary malware to conduct the infection.
  • A set of C2 servers and distribution domains for command and control and the download of .WNCRY file virus’ payload.

Even though the WanaCrypt0r 2.0 ransomware may spread via torrent websites, fake updates or other fake setups and executables uploaded on shady hots, the virus’s primary method of spreading may be via convincingly created e-mails. Such e-mails aim to get victims to click on a malicious e-mail attachment and hence become infected with the .WNCRY file virus.

The attachments may usually be .js, .exe or other type of executable files, but in some situations they are also related with malicious macros. These malicious macros may be activated once the user enables the content on a document. Here is how this infection process is conducted:

The first infections of Wana Decrypt0r 2.0 have been in Germany, Russia, Taiwan, Turkey, Kazakhstan, Indonesia, Vietnam, Japan, Spain, Ukraine and the Philippines. But the countries number may rise very rapidly soon, since this pattern shows global distribution campaign.

.WNCRY File Virus How Does It Work

The main activity of the Wana Decrypt0r 2.0 ransomware virus after infection is to drop an embedded file into the folder where the infection file is located. The file is a password protected .zip, named wcry.zip. It has the following contents:

  • b.wnry
  • c.wnry
  • r.wnry
  • s.wnry
  • t.wnry
  • u.wnry
  • taskse.exe
  • taskdl.exe

The Wana Decrypt0r 2.0 ransomware’s infection file will then extract those zipped files into a folder and begin to connect to the download web page of the TOR web browser. From there, the .Wana Decrypt0r 2.0 virus may connect to multiple command and control servers:

  • 57g7spgrzlojinas.onion
  • xxlvbrloxvriy2c5.onion
  • 76jdd2ir2embyv47.onion
  • cwwnhwhlz52maqm7.onion

Then, Wana Decrypt0r 2.0 prepares for encrypting vital victim files. To do this, it runs an administrative command in Windows in order to obtain Administrator functions:

→ icacls . /grant Everyone:F /T /C /Q

Then, the Wana Decrypt0r 2.0 virus shuts down the following Windows System processes from the Task Manager:

→ Mysqld.exe

The payload may consist of multiple different types of files. Some of those files may modify the Windows Registry Editor and target the following sub-keys:

→ HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
HKCU\Control Panel\Desktop\Wallpaper

In those keys, custom value strings with data in them may be input so that it is possible for the ransomware to run on system startup and begin encrypting files on boot.

In addition to the activity of WanaCrypt0r .WNCRY infection may be to delete the shadow volume copies and eradicate all chances of reverting your files via backup on the infected computer. This is done by executing the following administrative Windows commands:

→ vssadmin delete shadows /all /quiet
wmic shadowcopy delete
bcdedit /set boostatuspolicy ignoreallfailures
bcdedit /set {default} recoveryenabled no & wbadmin delete catalog -quiet

In addition to this activity, WannaCry .WNCRY virus also drops a program, named @WanaDecryptor@.exe that has an actual timer with advanced instructions on how to pay the ransom. This program is called “Wana Decrypt0r 2.0” and it’s message looks like the following:

After the timer on this program runs out the cost of the ransom payoff may double, according to the scareware messages and the previous version, also using this software.

Another action the program makes is that it also changes the wallpaper on the victim’s computer with the following message:

Ooops, your important files are encrypted.
If you see this text, but don’t see the ”Wana Decrypt0r” window,
then your antivirus removed the decrypt software or you deleted it from your computer.
If you need your files you have to run the decrypt software.
Please find an application file named “@WanaDecryptor@.exe” in any folder or restore from the antivirus quarantine.
Run and follow the instructions!

.WNCRY File Virus – Encryption Process

Two encryption algorithms may be used for this specific ransomware infection. One of those is known as AES (Advanced Encryption Standard) and may be used in 128-bit of strength. It is one of the strongest ciphers and cannot be decrypted unless the criminals make a mistake in the encryption code. It may generate a symmetric key, called FEK key after encryption. This key may be the only method to decrypt the files because with it the process can be reversed.

In addition to this, another cipher known as Rivers-Shamir-Adleman or RSA is also used in combination with the AES cipher in order to generate unique public and private keys for each of the files. This makes the decryption of each file separate and very difficult and unique process.

For the encryption process, the .WNCRY virus targets files that are widely used. These files are usually the following:

→ .ldf, .sln, .suo, .cpp, .pas, .asm, .cmd, .bat, .vbs, .dip, .dch, .sch, .brd, .jsp, .php, .class, .wav, .swf, .fla, .wmv, .mpg, .vob, .mpeg, .asf, .avi, .mov, .mkv, .flv, .wma, .mid, .djvu, .svg, .psd, .nef, .tiff, .tif, .cgm, .raw, .gif, .png, .bmp, .jpg, .jpeg, .vcd, .iso, .backup, .zip, .rar, .tgz, .tar, .bak, .tbk, .PAQ, .ARC, .aes, .gpg, .vmx, .vmdk, .vdi, .sldm, .sldx, .sti, .sxi, .hwp, .snt, .onetoc2, .dwg, .pdf, .wks, .rtf, .csv, .txt, .vsdx, .vsd, .edb, .odp, .otp, .sxd, .std, .uop, .odg, .otg, .sxm, .mml, .lay, .lay6, .asc, .sqlite3, .sqlitedb, .sql, .accdb, .mdb, .dbf, .odb, .frm, .myd, .myi, .ibd, .mdf, .msg, .ost, .pst, .potm, .potx .eml, .der, .pfx, .key, .crt, .csr, .pem, .odt, .ott, .sxw, .stw, .uot, .max, .ods, .ots, .sxc, .stc, .dif, .slk, .asp, .java, .ppam, .ppsx, .ppsm, .pps, .pot, .pptm, .pptx, .ppt, .xltm, .xltx, .xlc, .xlm, .xlt, .xlw, .xlsb, .xlsm, .xlsx, .xls, .dotx, .dotm, .dot, .docm, .docb, .docx, .doc, .jar

After the encryption is done, the .WNCRY virus may send the decryption key to the cyber-criminals so that they can create a custom decrypter for the victim which will be sent back to him once the ransom is paid. Paying the ransom, however is highly inadvisable.

The files have an added .WNCRY file extension to them which is unique for the infection. The files may appear like the following and cannot be opened with any software:

This attachment is usually masked as an important document, like an invoice, bank document or even a plane ticket and it looks very convincing to users. 

After you download and execute this attachment, a drive-by download occurs and your computer is infected with the ransomware virus.

Another way you may become a victim of .WNCRY is if you download a fake installer, crack or patch from a low reputation website or if you click on a virus link. Many users report getting a ransomware infection by downloading torrents.

How to Open ..WNCRY files?

You can't. At this point, the ..WNCRY files are encrypted. You can only open them once they are decrypted using a specific decryptionkey for the particular algorithm.

What to Do If a Decryptor Does Not Work?

Do not panic, and backup the files. If a decryptor did not decrypt your ..WNCRY files successfully, then do not despair, because this virus is still new.

Can I Restore "..WNCRY" Files?

Yes, sometimes files can be restored. We have suggested several file recovery methods that could work if you want to restore ..WNCRY files.
