Remove RSA-2048 Files Encrypted (Virus Removal Guide)

If your pictures, videos and documents are encrypted with a RSA-2048 key, and window is asking for money (Bitcoins/BTC)  to recover the files, then your computer has been infected with the file-encrypting ransomware.
These file-encrypting ransomware programs are malware, which will encrypt the personal documents found on victim’s computer using RSA-2048 key (AES CBC 256-bit encryption algorithm). Then displays a message which offers to decrypt the data if a payment (with Bitcoins) is made within 96 hours, otherwise the data will be destroyed.
The most known version of “RSA-2048 Files Encrypted” ransomware are: CryptoLocker, Crypt0l0cker, Alpha Crypt, TeslaCrypt, CoinVault, Bit Crypt, CTB-Locker or TorrentLocker.

1. How did the RSA-2048 Files Encryptedvirus got on my computer?

The RSA-2048 Files Encrypted ransomware 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 RSA-2048 Files Encrypted ransowmare

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 RSA-2048 Files Encrypted Ransomware?

The RSA-2048 Files Encrypted is a ransomware program which targets all versions of Windows including Windows XP, Windows Vista, Windows 7, and Windows 8. 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 RSA-2048 Files Encrypted 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.
RSA-2048 Files Encrypted 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 append a new  extension (.ezz, .exx, .7z.encrypted) to the file name.
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

While encrypting your files, this ransomware may create a text file ransom note in each folder that a file has been encrypted and on the Windows desktop. The ransomware ,may also change your Windows desktop wallpaper. Both the wallpaper and the text ransom note will contain the same information on how to access the payment site and get your files back.

The RSA-2048 Files Encrypted ransomware will also hijack your .EXE extensions so that when you launch an executable it will attempt to delete the Shadow Volume Copies that are on the affected computer. It does this because you can use shadow volume copies to restore your encrypted files. Once the infection has successfully deleted your shadow volume copies, it will restore your exe extensions back to the Windows defaults.

When it has finished encrypting your data files it will then show the RSA-2048 Files Encrypted at the end of your personal documents, and a screen demanding a ransom in order to decrypt your files. It also states that you must pay this ransom within 96 hours or the private encryption key will be destroyed on the developer’s servers.

3. Is my computer infected with RSA-2048 Files Encrypted virus?

If your computer is infected with this type of ransomware, your desktop wallpaper will be changed and a “RSA-2048 Files Encrypted” window with a countdown timer wil be displayed.

The messages displayed by this ransomware infection can be localized depending on the user’s location, with text written in the appropriate language. This is the usual message that the RSA-2048 Files Encrypted virus may display:

Your Files Have Been Encrypted!
Your files have been safely encrypted on this PC: photos, videos, documents, etc. Click “Show encrypted files” Button to view a complete list of encrypted files, and you can personally verify this. Encryption was produced using a unique public key RSA-2048 generated for this computer. To decrypt files you need to obtain the private key. The only copy of the private key, which allow you to decrypt your files, is located on a secret server in the Internet; the server will eliminate the key after a time period specified in this window.
Once this has been done, nobody will ever be able to recover.

4. Is it possible to decrypt files encrypted by RSA-2048 Files Encrypted ransomware?

No, at this time it’s not possible.

The RSA-2048 Files Encrypted 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.

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 adress to the law enforcement agency in your country to report this attack.
