Remove Duk Virus (.[dokulus@tutanota.com].duk Files Ransomware) – Dharma Ransomware

Duk – Ransomware

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

The message given by Duk text file requesting the ransom is definitely the like the statements given by other ransomware virus representatives belonging to the Dharma type. It actually discusses that the information is encrypted which the only way to bring back it is to use a a special decryption key. Sadly, this is definitely true. The type of cryptography mechanism used by Duk is still not properly examined. Still, it is definitely particular that each victim might be given the specific decryption key, which is absolutely distinct. It is difficult to restore the files without the key available.

Another trick of Duk is that the victims cannot gain access to the key. The key is stored on a specific server run by the frauds related to Duk ransomware. To get the key and recover the important information people have to pay the ransom.

Nevertheless, regardless of the requested amount, people must stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to completely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive result and people simply waste their money for nothing.

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