Dec Virus Ransomware

The Dec mean a ransomware-type infection. The infection comes from the Dharma ransomware family. Dec was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Dec adds the “.[de_cryption@tuta.io].dec” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Dec, will be renamed into “myphoto.jpg.[de_cryption@tuta.io].dec“. As quickly as the encryption is completed, Dec places a special text file into every folder containing the encrypted data.

The message given by Dec text file requesting the ransom is absolutely the like the statements given by other ransomware representatives belonging to the Dharma family. It literally discusses that the information is encrypted which the only way to bring back it is to use a an unique decryption key. Regretfully, this is definitely true. The kind of cryptography mechanism applied by Dec is still not correctly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is completely distinct. It is impossible to bring back the files without the key available.

Another trick of Dec is that the victims cannot get to the key. The key is saved on a specific server run by the frauds connected with Dec ransomware. To get the key and recover the important info people have to pay the ransom.

Nevertheless, regardless of the asked for amount, people must keep away from paying the ransom virus. Cyber frauds are not fair, so they tend to totally disregard what their victims feel about the issue, even when the payment reaches their pockets.

We strongly advise 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 Dec ransomware and to recover the information data totally free. Hence, the just right decision is to recover the lost data from the available backup.
