Cyber crooks have brought Bart ransomware virus back in the game – this time it’s called Bart v2.0 (also Bart2) and appends encrypted files with the .bart2 extension.
Bart v2.0 is considered an improved version from its predecessor Bart, for which developers have managed to release a decryptor.

|Encrypts the user’s files with a strong encryption algorithm and requests to contact e-mail address to make a ransom payoff of approximately 2000 dolalrs in BitCoin.
|Files are encrypted and become inaccessible and a .bart.zip file extension is being added to them. A ransom note is left as a text file as well as a wallpaper.

How Does Bart V2.0 Ransomware Virus Spread?
Bart v2.0 spreads just like its predecessor – via a botnet. The botnet is a network of machines capable of infecting different users across the world at the same time by sending huge quantities of infections all at once. Keep in mind that if your system, applications, protection, etc. are outdated, Bart v2.0 will be able to break into your PC successfully. Thus it’s very important to update your anti-malware program on a regular basis.
Spam emails are also a way to spread ransomware viruses. Users who bluntly trust anything they receive in the inbox, are the ones who fall victims of ransomware infections the most. Spam emails are usually disguised as legitimate ones, but they contain compromised URLs and file attachments. Once opened, the virus begins its installation.
How Does Bart V2.0 Work?
Bart ransomware is believed to be created by the same authors of Locky and Cerber3 viruses. And, although a decryption tool for Bart was released at the end of June this year, it still managed to cause a whole lot of trouble.
Apparently, cyber crooks have learnt their lesson after developers released a decryption tool for the first Bart. They have now released Bart v2.0 with several improvements. Its encryption is surely the most important improvement as it now requires more efforts to decrypt the affected files.
Also, the encrypted files receive the extention .bart2. Bart v2.0 is likely to look for the following files to encrypt:
.123, .3dm, .3ds, .3g2, .3gp, .602, .aes, .arc, .asc, .asf, .asm, .asp, .avi, .bak, .bat, .bmp, .brd, .cgm, .cmd, .cpp, .crt, .csr, .csv, .dbf, .dch, .dif, .dip,
.djv, .djvu, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .fla, .flv, .frm, .gif, .gpg, .hwp, .ibd, .jar, .java, .jpeg, .jpg, .key, .lay, .lay6, .ldf, .m3u, .m4u, .max, .mdb, .mdf, .mid, .mkv, .mov, .mp3, .mp4, .mpeg, .mpg, .ms11, .myf, .myi, .nef, .odb, .odg, .odp, .ods, .odt, .otg, .otp, .ots, .ott, .p12, .paq, .pas, .pdf, .pem, .php, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .psd, .rar, .raw, .rtf, .sch, .sldm, .sldx, .slk, .stc, .std, .sti, .stw, .svg, .swf, .sxc, .sxd, .sxi, .sxm, .sxw, .tar, .tbk, .tgz, .tif, .tiff, .txt, .uop, .uot, .vbs, .vdi, .vmdk, .vmx, .vob, .wav, .wb2, .wk1, .wks, .wma, .wmv, .xlc, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .zip
Unlike the first Bart which compiled the locked files into .zip folders requiring a password for decryption, Bart 2 ransomware now uses the AES and RSA encryption methods.
While the first version of Bart used the same password for all locked data folders, the new Bart v2.0 is reported to use different passwords for the different folders.
After the encryption of the files has finished, Bart v2.0 will drop a file with instructions which read like this:
“Your files have been encrypted by Bart2!
What happened to your files?
All of your files were protected by a strong encryption with RSA4096
More information about the encryption keys using RSA4096 can be found here: https://en.wikipedia.org/wiki/RSA_(cryptosystem)
How did this happen?
!!!Specially for your PC was generated
personal key, both public and private.
!!! ALL YOUR FILES were encrypted with the
public key, which has been transferred to
your computer via the Internet.
!!! Decrypting of your files is only possible
with the help of the private key and decrypt
program, which is on our Secret Server.
Remove Bart 2 and Restore Encrypted Data
We strongly urge you to not pay the demanded amount and remove the virus from your systems first. Only then you could try to restore some of the encrypted data.

Another way you may become a victim of Bart2 is if you download a fake installer, crack or patch from a low reputation website or if you click on a virus link. Many users report getting a ransomware infection by downloading torrents.
How to Open .Bart2 files?
You can't without a decryptor. At this point, the .Bart2 files are encrypted. You can only open them once they are decrypted using a specific decryption key for the particular algorithm.
What to Do If a Decryptor Does Not Work?
Do not panic, and backup the files. If a decryptor did not decrypt your .Bart2 files successfully, then do not despair, because this virus is still new.
Can I Restore ".Bart2" Files?
Yes, sometimes files can be restored. We have suggested several file recovery methods that could work if you want to restore .Bart2 files.

Can Bart2 Ransomware Steal Your Data?
Yes, in most cases ransomware will steal your information. It is a form of malware that steals data from a user's computer, encrypts it, and then demands a ransom in order to decrypt it.
Can Ransomware Infect WiFi?
Yes, ransomware can infect WiFi networks, as malicious actors can use it to gain control of the network, steal confidential data, and lock out users. If a ransomware attack is successful, it could lead to a loss of service and/or data, and in some cases, financial losses.
Should I Pay Ransomware?
No, you should not pay ransomware extortionists. Paying them only encourages criminals and does not guarantee that the files or data will be restored. The better approach is to have a secure backup of important data and be vigilant about security in the first place.
What Happens If I Don't Pay Ransom?
If you don't pay the ransom, the hackers may still have access to your computer, data, or files and may continue to threaten to expose or delete them, or even use them to commit cybercrimes. In some cases, they may even continue to demand additional ransom payments.
Can a Ransomware Attack Be Detected?
Yes, ransomware can be detected. Anti-malware software and other advanced security tools can detect ransomware and alert the user when it is present on a machine.
It is important to stay up-to-date on the latest security measures and to keep security software updated to ensure ransomware can be detected and prevented.
Do Ransomware Criminals Get Caught?
Yes, ransomware criminals do get caught. Law enforcement agencies, such as the FBI, Interpol and others have been successful in tracking down and prosecuting ransomware criminals in the US and other countries. As ransomware threats continue to increase, so does the enforcement activity.
