CryptXXX 3.0 is a file-encrypting ransomware, which will encrypt the personal documents found on victim’s computer using RSA-2048 key (AES CBC 256-bit encryption algorithm), appending the .crypz extension to encrypted files. CryptXXX 3.0 then displays a message which offers to decrypt the data if a payment of about 2.4 bitcoins, or approximately $1,000 USD is made.
06 June 2016: We cannot help your recover your files, and we can only 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 decryptor available for the CryptXXX 3.0 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 CryptXXX 3.0 ransomware got on my computer?
The CryptXXX 3.0 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 CryptXXX 3.0 ransomware.
2. What is CryptXXX 3.0 Ransomware?
The CryptXXX 3.0 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 AES-265 and RSA encryption method – in order to ensure that the affected user has no choice but to purchase the private key.
When the CryptXXX 3.0 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.
CryptXXX 3.0 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 .crypz, so they are no longer able to be opened.
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 .crypz exntesion, the CryptXXX 3.0 ransomware will create the !Recovery_[victim_id].txt text files ransom note in each folder that a file has been encrypted and on the Windows desktop. The ransomware will also change your Windows desktop wallpaper to !Recovery_[victim_id].png.
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 CryptXXX 3.0 virus?
When CryptXXX 3.0 infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the .crypz extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When CryptXXX 3.0 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 CryptXXX Decrypt Service where you can learn more about what happened to your files and how you can make a CryptXXX ransom 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 CryptXXX 3.0 ransomware may display:

4. Is it possible to decrypt files encrypted by CryptXXX 3.0?
No, at this time it’s not possible to recover the files encrypted by the CryptXXX 3.0 ransomware.
CryptXXX 3.0 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 CryptXXX 3.0 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.
Restore your files encrypted by CryptXXX 3.0 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 CryptXXX 3.0 ransomware with ShadowExplorer
CryptXXX 3.0 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.
- You can download ShadowExplorer from the below link:
SHADOW EXPLORER DOWNLOAD LINK (This link will open a new web page from where you can download “ShadowExplorer”) - Once you have downloaded and installed ShadowExplorer, you can follow the below video guide on how to restore your files while using this program.
Alternatively, you can use the System Restore to try to recover the encrypted documents.
Option 2: Restore your files encrypted by CryptXXX 3.0 ransomware with File Recovery Software
When CryptXXX 3.0 encrypts a file it first makes a copy of it, encrypts the copy, and then deletes the original. Due to this you can use file recovery software such as:
- Recuva
You can follow the below guide on how to use Recuva:
- EaseUS Data Recovery Wizard Free
- R-Studio

ya hay alguna actualización?
Thank you very much for your work and your invaluable
information. We were able to get back the data of previous ShadowCopy and to
disinfect the PC. Our antivirus did not know how to recognize the Malware and at present
no update… Have you got some news concerning the treatment of this
Malware? Friendly
Admin,i have one doubt recently I have also been affected by this cryptxxx 3.0, it encrypts all my data except my iso nd exe files,is there any motive for hacker to intentionally to leave
Thank you, I’ve corrected the text. Sadly there is no decryptor available for this ransomware yet.
You are saying at the begining of the article “There is now” and I think this is typo. Please correct it since this can mislead to somebody that have a PC infected (like me) and is looking for a solution to decrypt the files.
