Remove Dexx Virus (.[decryptex@airmail.cc].dexx Files Ransomware) – Dharma Ransomware

Dexx Virus – Details

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

The message given by Dexx text file asking for the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Dharma family. It literally mentions that the info is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is definitely true. The type of cryptography mechanism used by Dexx is still not correctly examined. Still, it is absolutely particular that each victim may be given the specific decryption key, which is completely distinct. It is impossible to restore the files without the key available.

Another trick of Dexx is that the victims cannot get to the key. The key is saved on a particular server run by the frauds related to Dexx ransomware. To get the key and recover the important information people need to pay the ransom.

However, irrespective of the requested amount, people need to keep away from paying the virus. 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 usually does not provide any positive result and people simply waste their money for nothing.

We highly encourage 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 Dexx ransomware and to recover the data data for free. Therefore, the only right decision is to recover the lost information from the available backup.
