Remove DT Virus (.[datos@onionmail.org].DT Files Ransomware) – Dharma Ransomware

DT – General Info

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

The message given by DT text file requesting the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Dharma type. It literally 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 sort of cryptography mechanism used by DT is still not correctly examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is totally unique. It is impossible to bring back the files without the key available.

Another trick of DT is that the victims cannot get to the key. The key is kept on a particular server run by the frauds associated with DT 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 ransom. Cyber frauds are not fair, so they tend to entirely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom typically does not give any positive outcome and people simply lose their money for absolutely nothing.

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