Boston Virus Removal Guide (+Decode .boston files) – Djvu Ransomware

Boston – General Info

The Boston mean a ransomware-type infection. The virus comes from the Djvu ransomware family. Boston was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Boston adds the “.boston” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Boston, will be renamed into “myphoto.jpg.boston“. As quickly as the encryption is completed, Boston places a special text file into every folder containing the encrypted data.

The message given by Boston text file requesting for the ransom is definitely the same as the statements given by other ransomware virus representatives belonging to the Djvu type. It actually mentions that the information is encrypted and that the only way to restore it is to use a a special decryption key. Unfortunately, this is definitely true. The type of cryptography mechanism used by Boston is still not properly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is completely unique. It is difficult to bring back the files without the key available.

Another technique of Boston is that the victims cannot get to the key. The key is kept on a specific server run by the frauds related to Boston ransomware. To get the key and recover the important info people need to pay the ransom, which amounts to $980. To obtain the payment details users are instructed to contact the frauds through email or telegram. The alert also indicates that the users need to contact the Boston developers within 72 hours after the files encryption took place. The message says that doing so users will get a 50% discount, so the ransom amount will drop down to $490.

Nonetheless, regardless of the asked for amount, people must stay away from paying the ransom virus. Cyber frauds are not fair, so they tend to totally ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom usually does not give any positive result and people simply waste their money for nothing.

We highly encourage that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Boston ransomware and to recover the information data free of charge. Hence, the only best decision is to recover the lost information from the available backup.
