Remove UltraCrypter ransomware (.cryp1 Files Encrypted)

UltraCrypter 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 .cryp1 extension to encrypted files. UltraCrypter then displays a message which offers to decrypt the data if a payment of 1.2 Bitcoins (around 500$) is made.

1. How did the UltraCrypter ransomware got on my computer?

The UltraCrypter 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 UltraCrypter ransomware.

2. What is UltraCrypter Ransomware?

The UltraCrypter 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 UltraCrypter 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.
UltraCrypter 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 .cryp1, 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 .cryp1 exntesion, the UltraCrypter ransomware will create the [Victim’s personal 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 [Victim’s personal 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 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 UltraCrypter virus?

If your computer is infected with the UltraCrypter ransomware will display a [Victim’s personal ID].png wallpaper that covers the entire desktop, and all your documents will have a .cryp1 extension. A [Victim’s personal ID].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 UltraCrypter ransomware may display:

All you data (photos, documents, database, …) have been encrypted with a private and unique key generated for this computer.
It means that you will not be able to access your files anymore until they’re decrypted. The private key is stored in our servers and the only way to receive your key to decrypt your files is making a payment.
The payment has to be done in Bitcoin to a unique address that we generated for you, Bitcoins are a virtual currency to make online payments. If you don’t know how to get Bitcoins, you can google “How to Buy Bitcoins” and follow the instructions.

4. Is it possible to decrypt files encrypted by UltraCrypter?

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

UltraCrypter 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.

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.
