DualShot Virus – Details

The DualShot stands for a ransomware-type infection. DualShot was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are not able to use them. DualShot adds the “.dsec” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by DualShot, will be renamed into “myphoto.jpg.dsec“. As soon as the encryption is finished, DualShot places a special text file into every folder containing the encrypted data.

The message given by DualShot text file requesting for the ransom is absolutely the like the statements given by other ransomware virus representatives. It literally mentions that the information is encrypted and that the only way to bring back it is to use a a distinct decryption key. Unfortunately, this is definitely true. The type of cryptography mechanism applied by DualShot is still not properly examined. Still, it is definitely particular that each victim might be given the specific decryption key, which is totally distinct. It is impossible to restore the files without the key available.

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

Nevertheless, regardless of the requested amount, people must stay away from paying the ransom. Cyber frauds are not fair, so they tend to totally 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 outcome and people simply lose their money for nothing.

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