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 Bart ransomware. However, you can try to search these webpages for updates: http://www.bleepingcomputer.com/forums/t/618157/bart-ransomware-help-support-bartzip-recoverytxt/ or https://id-ransomware.malwarehunterteam.com/

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

The Bart 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 Bart ransomware.

2. What is Bart Ransomware?

The Bart 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, unlike most ransomware, the Bart ransowmare simply places its targeted files in individual zip archives and applies password protection to these archives.

When the Bart 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.
Bart 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 .bart.zip, so they are no longer able to be opened. This ransomware places its targeted files in individual zip archives and applies password protection to these archives.

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 .bart.zip extension, the Bart ransomware will create the recover.txt 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 recover.bmp.
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 Bart virus?

When Bart infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the .bart.zip extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When Bart 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 (recover.html) in your default browser. These ransom notes include instructions on how to connect to the Bart Decrypt Service where you can learn more about what happened to your files and how you can make a Bart ransom payment.

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

No, at this time it’s not possible to recover the files encrypted by the Bart ransomware. Unfortunately, once the Bart encryption of the data is complete, decryption is not feasible without paying the ransom.

Because the needed zip password 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 Bart 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 Bart ransomware with ShadowExplorer

Bart 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.

  1. 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”)
  2. 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 Bart ransomware with File Recovery Software

When Bart 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:
