Analysis of Bart ransomware virus

It seems that Bart virus belongs to infamous Locky ransomware family – it uses the same distribution techniques, has similar payment website and after data encryption, it changes affected computer’s background with a similar picture. This file-encrypting virus uses aggressive techniques to take victim’s files to hostage; however, it is slightly different from other ransomware. It does not need an Internet connection to encrypt user’s data and does not communicate with Command and Control servers. Usually, ransomware viruses use AES or RSA algorithms for data encryption. Meanwhile, Bart ransomware creates password-protected ZIP archives and appends .bart extension to all of them. Indeed, victims need to purchase the necessary password to get back access to their personal documents. Before talking further about features of this nasty malware, we want to tell you some good news. Virus researchers have already created a free decryption tool, so there’s no need to pay 3 Bitcoins and sponsor the crooks! Remove Bart with a help of Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus and then recover your personal files.

Computer users rarely can tell when the ransomware attack occurred. However, they can clearly identify the signs of the hack. Bart virus not only locks files but also changes desktop’s wallpaper with a ransom message that encourages to check recover.txt file. Indeed, it’s a ransom note where victims can learn why they have lost access to their data and how they can get it back. In this case, all creators of ransomware do the same – they ask to pay the money. The only difference is that they provide different versions of the ransom note, use different psychological terror techniques and offers to read the message in a different language. Victims can read the letter from the creators of Bart malware in French, German, Italian and Spanish languages. Besides, the virus has one unique and strange feature. After infiltration, it checks computer’s language settings and only then starts encryption process or… uninstalls itself. Yes. There’s a possibility to avoid this virus if your default computer’s language is Russian, Ukrainian or Belorussian. However, virus actively targets the US and other big countries all over the world. If malware appeared on your computer, do not hesitate and initiate Bart removal.

Versions of Bart virus

The authors of ransomware do not give up and take their illegal job seriously. As soon as malware researchers have created a free decryption tool, hackers updated the ransomware two times:

Bart v2.0 ransomware. It’s the first version of Bart virus. Instead of adding files to archive, the virus encrypts them and adds .bart2 file extension. Unfortunately, malware researchers haven’t created a free decryption tool yet, so there’s no possibility to restore corrupted files. Of course, hackers offers to purchase a Bart decryptor and restore files using it. However, we do not recommend paying the ransom. Remove Bart v2.0 from the system and retrieve data from backups. If you don’t have them, you should wait for free decryption software.

Perl ransomware virus. The second version of the virus barely differs from the first. It seems that the main difference is a new file extension. To the encrypted data it appends .perl file extension. Hackers also ask to pay the ransom and try to convince victims that it’s the only possibility to restore their files. Even though it’s impossible to decrypt files for free yet, you should not consider paying the ransom. Cyber criminals tend to disappear after receiving payment. It’s better to remove malware and think about additional data recovery methods.

Malware distribution techniques

All version of Bart virus uses similar distribution techniques. The main way how the virus spreads is malicious email attachments. Infected emails usually have a subject line ‘Photos’ and include .zip attachments with JavaScript code. The attachments are named Photos.zip, Image.zip, Picture.zip or similarly. Once the victim opens the file, the virus gets into the system and starts damaging the files. To avoid malware, you should be careful with your emails. Before opening any attachment or link provided in the email, make sure if you can trust the sender. In this case, think why someone sends you some pictures? Do you know the sender? If not, do not let your curiosity cause you problems.
