Wana Decrypt0r 2.0 is a file-encrypting ransomware, which will encrypt the personal documents found on victim’s computer using a combination of RSA and AES-128-CBC algorithm, appending the .WNCRY extension to the encrypted files. The Wana Decrypt0r 2.0 ransomware then displays a message which offers to decrypt the data if a payment of $300 worth of bitcoins is made.

1. How did the Wana Decrypt0r 2.0 ransomware get on my computer?
The Wana Decrypt0r 2.0 ransomware is distributed via spam email containing infected attachments or links to malicious websites. Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the Wana Decrypt0r 2.0 ransomware.
2. What is Wana Decrypt0r 2.0 ransomware?
The Wana Decrypt0r 2.0 ransomware targets all versions of Windows including Windows 10, Windows 8 and Windows 7. 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.
Wana Decrypt0r 2.0 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 2.0 changes the name of each encrypted file to the following format: .WNCRY.
The Wana Decrypt0r 2.0 ransomware then searches all available drives and network shares for files with one of the following extensions:
.der, .pfx, .key, .crt, .csr, .p12, .pem, .odt, .ott, .sxw, .stw, .uot, .3ds, .max, .3dm, .ods, .ots, .sxc, .stc, .dif, .slk, .wb2, .odp, .otp, .sxd, .std, .uop, .odg, .otg, .sxm, .mml, .lay, .lay6, .asc, .sqlite3, .sqlitedb, .sql, .accdb, .mdb, .db, .dbf, .odb, .frm, .myd, .myi, .ibd, .mdf, .ldf, .sln, .suo, .cs, .cpp, .pas, .asm, .js, .cmd, .bat, .ps1, .vbs, .vb, .pl, .dip, .dch, .sch, .brd, .jsp, .php, .asp, .rb, .java, .jar, .class, .sh, .mp3, .wav, .swf, .fla, .wmv, .mpg, .vob, .mpeg, .asf, .avi, .mov, .mp4, .3gp, .mkv, .3g2, .flv, .wma, .mid, .m3u, .m4u, .djvu, .svg, .ai, .psd, .nef, .tiff, .tif, .cgm, .raw, .gif, .png, .bmp, .jpg, .jpeg, .vcd, .iso, .backup, .zip, .rar, .7z, .gz, .tgz, .tar, .bak, .tbk, .bz2, .PAQ, .ARC, .aes, .gpg, .vmx, .vmdk, .vdi, .sldm, .sldx, .sti, .sxi, .602, .hwp, .snt, .onetoc2, .dwg, .pdf, .wk1, .wks, .123, .rtf, .csv, .txt, .vsdx, .vsd, .edb, .eml, .msg, .ost, .pst, .potm, .potx, .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, .c, .h
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.
Once done, the malware will generate a new 128 bit AES key for every file it found, which is encrypted using the public RSA key generated earlier and the RSA-encrypted AES key is stored within the header of the encrypted file, together with the file marker “WANACRY!”. The AES key is then used to encrypt the file’s content.
3. Is my computer infected with Wana Decrypt0r 2.0 Ransomware?
When Wana Decrypt0r 2.0 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 Wana Decrypt0r 2.0 ransowmare has finished encrypting the victim’s files, it will also display a @Please_Read_Me@.txt ransom note. These @Please_Read_Me@.txt 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 @Please_Read_Me@.txt ransomware may display:

4. Is it possible to decrypt files encrypted by Wana Decrypt0r 2.0 ransomware?
No, at this time it’s not possible to recover the files encrypted by the Wana Decrypt0r 2.0 ransomware.
Wana Decrypt0r 2.0 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 Wana Decrypt0r 2.0 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.
