Remove Tohnichi Virus (.tohnichi Files Ransomware) – DelShad Ransomware

Tohnichi Virus Ransomware

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

The message given by Tohnichi text file asking for the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the DelShad type. It literally points out that the information is encrypted and that the only way to restore it is to use a a distinct decryption key. Regretfully, this is definitely true. The kind of cryptography mechanism applied by Tohnichi is still not appropriately examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely distinct. It is impossible to bring back the files without the key available.

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

Nonetheless, regardless of the requested amount, people should keep away from paying the virus. Cyber frauds are unfair, so they tend to completely disregard 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 simply lose their money for absolutely 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 Tohnichi ransomware and to recover the information data for free. Therefore, the just right decision is to recover the lost information from the available backup.
