Dex – General InfoThe Dex mean a ransomware-type infection. The infection comes from the Dharma ransomware family. Dex was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are not able to use them. Dex adds the “.[firstname.lastname@example.org].dex” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Dex, will be renamed into “myphoto.jpg.[email@example.com].dex“. As quickly as the encryption is finished, Dex places a special text file into every folder containing the encrypted data.
The message given by Dex text file requesting the ransom is definitely the same as the statements given by other ransomware representatives coming from the Dharma type. It actually points out that the information is encrypted and that the only way to bring back it is to use a a distinct decryption key. Sadly, this is absolutely true. The kind of cryptography mechanism applied by Dex is still not correctly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.
Another trick of Dex is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds related to Dex ransomware. To get the key and recover the important info people need to pay the ransom.
Nonetheless, irrespective of the requested amount, people should stay away from paying the virus. Cyber frauds are unfair, so they tend to entirely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom normally does not give any positive outcome and people simply lose their money for 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 Dex ransomware and to recover the information data for free. Hence, the only best decision is to recover the lost information from the available backup.
