Remove Nomikon Virus (+Decrypt .CNMHR files)

Nomikon Virus Ransomware

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

The message given by Nomikon text file asking for the ransom is definitely the like the statements given by other ransomware virus representatives. It literally points out that the information is encrypted which the only way to restore it is to use a a distinct decryption key. Regretfully, this is definitely true. The sort of cryptography mechanism applied by Nomikon is still not appropriately examined. Still, it is definitely particular that each victim may be given the specific decryption key, which is completely unique. It is impossible to bring back the files without the key available.

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

However, irrespective of the asked for amount, people should stay away from paying the virus. Cyber frauds are not fair, so they tend to entirely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom typically 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 definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Nomikon ransomware and to recover the data data for free. Hence, the just best decision is to recover the lost information from the available backup.
