Remove c0hen Virus (+Decrypt .c0hen files)

c0hen – General Info

The c0hen mean a ransomware-type infection. c0hen was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are unable to use them. c0hen adds the “.c0hen” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by c0hen, will be renamed into “myphoto.jpg.c0hen“. As soon as the encryption is finished, c0hen places a special text file into every folder containing the encrypted data.

The message given by c0hen 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 information is encrypted and that the only way to bring back it is to use a a distinct decryption key. Sadly, this is definitely true. The kind of cryptography mechanism used by c0hen is still not properly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is completely distinct. It is difficult to restore the files without the key available.

Another technique of c0hen is that the victims cannot access to the key. The key is stored on a specific server run by the frauds associated with c0hen ransomware. To get the key and recover the important information people have to pay the ransom.

Nevertheless, regardless of the requested quantity, people should stay away from paying the ransom. Cyber frauds are not fair, so they tend to entirely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people just waste their money for nothing.

We strongly recommend 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 c0hen ransomware and to recover the data data for free. Thus, the just right decision is to recover the lost data from the available backup.
