Remove Rhino Virus (+Decrypt .[generalchin@countermail.com].rhino files) – Marvel Ransomware

Rhino Virus – Details

The Rhino stands for a ransomware-type infection. The infection comes from the Marvel ransomware family. Rhino was elaborated particularly to encrypt all major file types. When the file is encrypted people are unable to use them. Rhino adds the “.[generalchin@countermail.com].rhino” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Rhino, will be renamed into “myphoto.jpg.[generalchin@countermail.com].rhino“. As soon as the encryption is finished, Rhino places a special text file into every folder containing the encrypted data.

The message given by Rhino text file requesting for the ransom is definitely the same as the statements given by other ransomware virus representatives belonging to the Marvel type. It literally mentions that the info is encrypted which the only way to restore it is to use a a special decryption key. Regretfully, this is absolutely true. The kind of cryptography mechanism applied by Rhino is still not properly examined. Still, it is definitely particular that each victim may be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.

Another trick of Rhino is that the victims cannot access to the key. The key is stored on a particular server run by the frauds associated with Rhino ransomware. To get the key and recover the important information people have to pay the ransom.

However, regardless of the requested amount, people must keep away from paying the ransom. Cyber frauds are unfair, 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 provide any positive result and people just waste their money for nothing.

We highly encourage that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Rhino ransomware and to recover the data data free of charge. Thus, the just right decision is to recover the lost data from the available backup.
