Cuba Virus Ransomware

The Cuba mean a ransomware-type infection. Cuba was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Cuba adds the “.cuba” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Cuba, will be renamed into “myphoto.jpg.cuba“. As soon as the encryption is finished, Cuba places a special text file into every folder containing the encrypted data.

The message given by Cuba text file requesting for the ransom is definitely the same as the statements given by other ransomware virus representatives. It actually points out that the info is encrypted which the only way to bring back it is to use a an unique decryption key. Sadly, this is absolutely true. The sort of cryptography mechanism used by Cuba is still not appropriately examined. Still, it is definitely specific that each victim may be given the specific decryption key, which is totally distinct. It is impossible to restore the files without the key available.

Another technique of Cuba is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds associated with Cuba ransomware. To get the key and recover the important info people have to pay the ransom.

However, irrespective of the asked for quantity, people must keep away from paying the virus. Cyber frauds are unfair, so they tend to totally ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom normally does not provide any positive result and people simply lose their money for nothing.

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