Modus operandi of Bart ransomware virus: encrypts files, demands ransom

Bart ransomware is a virus that encrypts all victim's data on the compromised computer. This malware variant appears to be created by Locky virus’ authors. Just like Locky, it spreads as a JS file, which utilizes RockLoader malware to silently download and install its infectious files on a compromised computer. What is more, Bart virus can work and corrupt victim’s files without using Internet connection, which means this virus cannot be stopped by disabling network connection. It does not communicate with its command and control server and does not send the unique decryption key to it, but it localizes the encryption procedure and uses a slightly different technique to make files inaccessible. Instead of encrypting them with RSA or AES encryption algorithms, Bart puts each file into a ZIP archive and protects it with a password. It appends .bart file extension to filenames, and that is where the name of this ransomware comes from. The archived file name looks like this: example.txt.bart.zip.

Note: We have discovered that this computer threat checks default language setting before running the encryption process and in case the default language is Russian, Ukrainian, or Belorussian, the virus stops and uninstalls itself. Otherwise, it continues to run.

Bart ransomware asks to pay 3 BTC

It is unlikely that this virus can leave any of your files unencrypted as it targets more than 160 different file types, which means that all files with file extensions that this virus targets will be corrupted, including documents, photos, audio, video files and many more. Just like any ransomware-type virus traditionally does, Bart malware leaves a ransom note, which is called recover.txt. The virus even provides several translations for the ransom note, including French, Spanish, German and Italian languages. Besides, it changes desktop background with recover.bmp image, which looks identical to the one that Locky virus shows. This ransom note points the user to a payment site, which can be accessed via TOR browser only. The payment site suggests Bart Decryptor for 3 BitCoins, which is nearly 2000 US dollars, and that is an exceedingly big ransom price. it is worth noting that this payment site looks very similar to Locky Decryptor's one. We do not recommend you to pay the ransom, as frauds might not provide you with the password for all these .bart.zip archives. Our suggestion is to remove Bart from your computer as soon as possible, and the best way to do it is to utilize an anti-malware program like Reimage.

It is possible to decrypt .Bart.zip file extension files

This malware is an exceptionally strong variant of ransomware, because creators of Locky know what they are doing very well. They have already created one of the most successful and uncrackable computer virus in the history of malware, which means their new virus is likely to be as strong as the previous one. Surprisingly, cyber security experts were able to create a decryption software already. You can download it here. You will need one original file and one corrupted variant of it to retrieve the password of these .bart.zip archives. Do not forget to remove Bart virus from computer before you start the decryption process!

Speaking of other ransomware variants, the only possible way to recover lost files is to import them from a backup, sadly, not many people care to create them on time. If you do not have backups, but if you want to learn how to create them, please read this article - How to backup your files? If you have a backup, you should remove the virus first and then plug in the storage device into your PC to import files.

Bart malware versions

Bart v2.0 ransomware. Since malware researchers have managed to create Bart decryption tool, criminals have upgraded the ransomware and released an undecryptable version, which does not add files to archives but encrypts them instead. This version has not been cracked yet, and it is not possible to recover files for free. The virus adds .bart2 file extensions to encrypted files and asks to pay a ransom. It places a ransom note on user's PC that informs where the user can purchase the Bart decrypter.

Perl ransomware virus. The latest version of Bart malware hardly differs from the second Bart version. The most noticeable difference is that it adds different file extensions to encrypted files - it renames them by adding .perl file extension. Reportedly, virus asks for a different sum of money from individual victims. Its ransom note also points users to Bart decrypter's payment site; however, you should not support criminals by paying them. Unfortunately, files encrypted by .perl file extension virus cannot be decrypted.

Bart distribution methods

This virus spreads via malicious email campaigns that deliver a .zip file attachment. Typically, authors of this ransomware send emails with a subject Photos. Files attached to these malicious emails are titled as image.zip, picture.zip, photos.zip and similarly. These archives carry JavaScript code, and if the user launches it, it immediately downloads and installs RockLoader malware, which is an intermediary loader. This malware downloads Bart virus and runs it. The easiest way to avoid infecting your PC with ransomware is to stay away from suspicious emails that come from unknown people or companies, and of course, keep the computer protected by installing the anti-malware software on it.

Bart removal guide

Please bear in mind that Bart virus is an extremely dangerous virus and that you cannot remove it manually unless you are a skilled IT expert. As we have said, this virus utilizes RockLoader malware, and you also need to remove it and all of its remains. Therefore, the best solution would be to run a system scan with a powerful anti-malware application. We have no doubts that Bart refuses to go away so easily and tries to stop the victim from deleting it, so that is why the 2-Spyware team has prepared instructions for you on how to do it properly.
