How to remove .WNCRY virus (@WanaDecryptor@ Ransomware)

If you cannot open your personal documents and they have the .WNCRY extension then your computer is infected with the Wana Decrypt0r ransowmare.
Wana Decrypt0r is a file-encrypting ransomware, which encrypts the personal documents found on victim’s computer, then displays a message which offers to decrypt the data if a payment of $300 is made. The instructions are placed on the victims desktop in the @Please_Read_Me@.txt file.

WNCRY Files Encrypted virus

@WanaDecryptor@ virus

We cannot help your recover your files, and we recommend that you use ShadowExplorer or (free) file recovery software to restore your documents. This guide was written to help you remove the infection itself, and if a 100% proven method to recover the encrypted files is found we will update this guide.
At this moment, there is no decryption tool available for the Wana Decrypt0r 2.0 (.WNCRY) ransomware. However, you can try to search these webpages for updates: https://decrypter.emsisoft.com/ or https://id-ransomware.malwarehunterteam.com

1. How did the WNCRY (@WanaDecryptor@) ransomware get on my computer?

WCry is primarily spreading via the leaked NSA exploits that the Shadow Brokers group released recently. More specifically, French researcher Kaffine was the first to suspect that WCry was being spread via the ETERNALBLUE exploit.

ETERNALBLUE exploits a vulnerability in the Microsoft SMBv1 protocol, allowing an attacker to take control over systems which:

  • have the SMBv1 protocol enabled
  • are accessible from the internet and
  • are have not been patched by the MS17-010 fix released back in March 2017

In addition, it appears that the malware authors are also taking advantage of DOUBLESPEAR, a backdoor that is usually installed via the ETERNALBLUE exploit and persisting on the system. So if your system was compromised by ETERNALBLUE previously, chances are your system is still vulnerable, even if the initial SMBv1 vulnerability was patched.


2. What is WNCRY (@WanaDecryptor@) ransomware?

The @WanaDecryptor@ ransomware targets all versions of Windows including Windows 7, Windows 8 and Windows 10. This infection is notable due to how it encrypts the user’s files – namely, it uses RSA and AES-128-CBC encryption method – in order to ensure that the affected user has no choice but to purchase the private key.

When the Wana Decrypt0r ransomware is first installed on your computer it will create a random named executable in the %AppData% or %LocalAppData% folder. This executable will be launched and begin to scan all the drive letters on your computer for data files to encrypt.
Wana Decrypt0r ransomware searches for files with certain file extensions to encrypt. The files it encrypts include important productivity documents and files such as .doc, .docx, .xls, .pdf, among others. When these files are detected, this infection will change the extension to .WNCRY, so they are no longer able to be opened.
Wana Decrypt0r changes the name of each encrypted file to the following format: Filename .WNCRY.

Files targeted are those commonly found on most PCs today; a list of file extensions for targeted files include:

.sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .gdb, .tax, .pkpass, .bc6, .bc7, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, .itl, .itdb, .icxs, .hvpl, .hplg, .hkdb, .mdbackup, .syncdb, .gho, .cas, .svg, .map, .wmo, .itm, .sb, .fos, .mov, .vdf, .ztmp, .sis, .sid, .ncf, .menu, .layout, .dmp, .blob, .esm, .vcf, .vtf, .dazip, .fpk, .mlx, .kf, .iwd, .vpk, .tor, .psk, .rim, .w3x, .fsh, .ntl, .arch00, .lvl, .snx, .cfr, .ff, .vpp_pc, .lrf, .m2, .mcmeta, .vfs0, .mpqge, .kdb, .db0, .dba, .rofl, .hkx, .bar, .upk, .das, .iwi, .litemod, .asset, .forge, .ltx, .bsa, .apk, .re4, .sav, .lbf, .slm, .bik, .epk, .rgss3a, .pak, .big, wallet, .wotreplay, .xxx, .desc, .py, .m3u, .flv, .js, .css, .rb, .png, .jpeg, .txt, .p7c, .p7b, .p12, .pfx, .pem, .crt, .cer, .der, .x3f, .srw, .pef, .ptx, .r3d, .rw2, .rwl, .raw, .raf, .orf, .nrw, .mrwref, .mef, .erf, .kdc, .dcr, .cr2, .crw, .bay, .sr2, .srf, .arw, .3fr, .dng, .jpe, .jpg, .cdr, .indd, .ai, .eps, .pdf, .pdd, .psd, .dbf, .mdf, .wb2, .rtf, .wpd, .dxg, .xf, .dwg, .pst, .accdb, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, .wps, .docm, .docx, .doc, .odb, .odc, .odm, .odp, .ods, .odt

Once your files are encrypted with the .WNCRY extension, the Wana Decrypt0r ransomware will create the @Please_Read_Me@.txt ransom note in each folder that a file has been encrypted and on the Windows desktop.
These files are located in every folder that a file was encrypted as well as in the user’s Startup folder so that they are automatically displayed when a user logs in. These files will contain the information on how to access the payment site and get your files back.

When the infection has finished scanning your computer it will also delete all of the Shadow Volume Copies that are on the affected computer. It does this so that you cannot use the shadow volume copies to restore your encrypted files.


3. Is my computer infected with WNCRY – Wana Decrypt0r Ransomware?

When Wana Decrypt0r ransowmare infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the .WNCRY extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When Loky ransowmare has finished encrypting the victim’s files, it will change the desktop wallpaper to an image that acts like a ransom note. It will also display a HTML ransom note in your default browser. These ransom notes include instructions on how to connect to the Decrypt Service where you can learn more about what happened to your files and how you can make a payment.

The messages displayed by this ransomware infection can be localized depending on the user’s location, with text written in the appropriate language.
This the message that the Wana Decrypt0r ransomware may display:

4. Is it possible to decrypt files encrypted with the *.WNCRY extension?

No, at this time it’s not possible to recover the files encrypted by the .WNCRY extension.

Wana Decrypt0r ransomware is notable due to how it encrypts the user’s files – namely, it uses AES-265 and RSA encryption method – in order to ensure that the affected user has no choice but to purchase the private key. The RSA public key can only be decrypted with its corresponding private key. Since the AES key is hidden using RSA encryption and the RSA private key is not available, decrypting the files is not feasible as of this writing.

Brute forcing the decryption key is not realistic due to the length of time required to break an AES encryption key. Unfortunately, once the .WNCRY encryption of the data is complete, decryption is not feasible without paying the ransom.
Because the needed private key to unlock the encrypted file is only available through the cyber criminals, victims may be tempted to purchase it and pay the exorbitant fee. However, doing so may encourage these bad guys to continue and even expand their operations. We strongly suggest that you do not send any money to these cyber criminals, and instead address to the law enforcement agency in your country to report this attack.

Restore the files encrypted by Wana Decrypt0r ransomware with recovery software

In some cases, it may be possible to recover previous versions of the encrypted files using System Restore or other recovery software used to obtain “shadow copies” of files.

Option 1: Restore your files encrypted by WNCRY – Wana Decrypt0r ransomware with ShadowExplorer

Wana Decrypt0r will attempt to delete all shadow copies when you first start any executable on your computer after becoming infected. Thankfully, the infection is not always able to remove the shadow copies, so you should continue to try restoring your files using this method.

Alternatively, you can use the System Restore to try to recover the encrypted documents.

Option 2: Restore your files encrypted with the .WNCRY extension with File Recovery Software

When the files are encrypted with the .WNCRY, this ransomware first makes a copy of them, encrypts the copy, and then deletes the original. Due to this you can use file recovery software such as:
