Bart ransomware virus: encrypts files without connecting to the Internet 

Bart ransomware (you can also find it named as Locky Bart[1]) is a virus that encrypts your files and asks you to pay for their decryption. This malware variant appears to be created by the same authors as Locky virus, OsirisThor, and Aesir. It has already initiated two attacks against PC users and, unfortunately, they both can be considered successful. Just like Locky, it spreads as a JS file utilizing RockLoader malware[2] 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, so it 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[3], ransomware puts each file into a ZIP archive and protects it with a password. It appends .bart file extension or file extension to the filenames, and removes the System Restore Points. The archived file name looks like this: If you can find these signs of infiltration on your computer, make sure you remove Bart ransomware from the system.

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.

The payment site of Bart ransomwareAccording to hackers, Decryptor Bart is needed to recover files encrypted by ransomware. Fortunately, security experts have already presented the legitimate decryption tool.

It is unlikely that this virus can leave any of your files unencrypted as it targets more than 160 different file types what 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, Locky Bart 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 looking 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.[4] 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 archives. Our suggestion is a quick Locky Bart removal. The best way to do it is to utilize an anti-malware program like Reimage Reimage Cleaner Intego.

Questions about Bart ransomware virus

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 what means their new virus is likely to be as strong as the previous one. Surprisingly, cyber security experts from AVG and AVAST have already created the decryption software for this ransomware.[5][6]. You will need one original file and one corrupted variant of it to retrieve the password of these 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 ransomware hardly differs from its second 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,, 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 uses RockLoader malware to infiltrate the system. It has to be removed as well to forget about further problems related to this ransomware. Therefore, the best solution for Bart ransomware removal is running a full system scan with a powerful anti-malware application. In this case, we recommend using Reimage Reimage Cleaner Intego or SpyHunter 5Combo Cleaner. We have no doubts that this ransomware will try using various techniques to prevent its elimination from your computer. If you can’t remove Bart virus because it keeps blocking your anti-spyware, follow instructions prepared by 2spyware security experts.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Bart from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

Victims who have their PCs infected with the first Bart ransomware version can decrypt their files for free. You can find data recovery instructions below.

If your files are encrypted by Bart, you can use several methods to restore them:

Recover your files encrypted with Bart ransomware with the help of Data Recovery Pro

If your files are locked by Bart ransomware, you can recover them with the help of Data Recovery Pro. It is a well-known tool which has been widely-used by PC users to revive lost files.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Bart ransomware;
  • Restore them.

Use Windows Previous Versions feature to recover files encrypted by Locky Bart virus

If you had System Restore function enabled on your computer before infiltration of this ransomware, you can try recovering the most useful files with Windows Previous Versions feature. For that, follow these steps:

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Use Bart decrypter to get your files back

Malware researchers from AVG and AVAST have already created free decryption tools helping victims decrypt their encrypted data for free. These tools can be downloaded from here: Bart decrypter, Decryption Tool for Bart.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Bart and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
