Remove CryptInfinite ransomware (Files Encrypted Malware)

CryptInfinite 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 .crinf extension to encrypted files.
CryptInfinite then displays a message which offers to decrypt the data if a payment $500 ransom is made within 24 hours with a PayPal MyCash voucher. If the user does not pay within this time frame, the ransom will increase to $1000.

1. How did the CryptInfinite virus got on my computer?

The CryptInfinite virus is distributed through several means. Malicious websites, or legitimate websites that have been hacked, can infect your machine through exploit kits that use vulnerabilities on your computer to install this Trojan without your permission of knowledge.

Another method used to propagate this type of malware is 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 CryptInfinite virus.

The threat may also be downloaded manually by tricking the user into thinking they are installing a useful piece of software, for instance a bogus update for Adobe Flash Player or another piece of software.

2. What is CryptInfinite Ransomware?

The CryptInfinite ransomware targets all versions of Windows including Windows XP, Windows Vista, 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 CryptInfinite 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.
CryptInfinite 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 .crinf, 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, the CryptInfinite ransomware will create the ReadDecryptFilesHere.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 ReadDecryptFilesHere.png.
These files are located in every folder that a file was encrypted as well as in the users Startup folder so that they are automatically displayed when a user logs in. These files will contain the informations 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 CryptInfinite virus?

If your computer is infected with the CryptInfinite ransomware will display a red ReadDecryptFilesHere.png wallpaper that covers the entire desktop, and all your documents will have a .crinf extension. A ReadDecryptFilesHere.txt text file will be placed on your desktop. Both files contain instruction on how or recover the encrypted files.

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 CryptInfinite ransomware may display:

Your personal files have been encrypted!

• Recuva
  You can follow the below guide on how to use Recuva:
  
• EaseUS Data Recovery Wizard Free
• R-Studio

How to prevent your computer from becoming infected by CryptInfinite

To protect your computer from the Cryptowall ransomware, you should always have an antivirus installed on your computer and always have a backup for your personal documents.
