Remove Blastoise Virus (.blastoise Files Ransomware)

Blastoise – Ransomware

The Blastoise stands for a ransomware-type infection. Blastoise was elaborated particularly to encrypt all major file types. Once the file is encrypted people are unable to use them. Blastoise adds the “.blastoise” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Blastoise, will be renamed into “myphoto.jpg.blastoise“. As soon as the encryption is completed, Blastoise places a special text file into every folder containing the encrypted data.

The message given by Blastoise text file asking for the ransom is definitely the same as the statements given by other ransomware representatives. It actually points out that the information is encrypted which the only way to bring back it is to use a a special decryption key. Unfortunately, this is definitely true. The sort of cryptography mechanism used by Blastoise is still not correctly examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is totally distinct. It is impossible to bring back the files without the key available.

Another trick of Blastoise is that the victims cannot access to the key. The key is saved on a specific server run by the frauds related to Blastoise ransomware. To get the key and recover the important info people have to pay the ransom.

Nevertheless, irrespective of the asked for quantity, people should stay away from paying the virus. Cyber frauds are not fair, so they tend to entirely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive result and people simply lose their money for absolutely nothing.

We strongly 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 Blastoise ransomware and to recover the information data free of charge. Thus, the just right decision is to recover the lost information from the available backup.
