Remove UPPER Virus (+Decrypt .UPPER files) – DelShad Ransomware

UPPER – General Info

The UPPER stands for a ransomware-type infection. The virus comes from the DelShad ransomware family. UPPER was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. UPPER adds the “.UPPER” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by UPPER, will be renamed into “myphoto.jpg.UPPER“. As quickly as the encryption is finished, UPPER places a special text file into every folder containing the encrypted data.

The message given by UPPER text file asking for the ransom is definitely the same as the statements given by other ransomware virus representatives belonging to the DelShad type. It literally points out that the information is encrypted which the only way to restore it is to use a an unique decryption key. Regretfully, this is definitely true. The sort of cryptography mechanism used by UPPER is still not properly examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is absolutely distinct. It is difficult to restore the files without the key available.

Another trick of UPPER is that the victims cannot get to the key. The key is stored on a particular server run by the frauds related to UPPER ransomware. To get the key and recover the important information people need 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 completely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive result and people just waste their money for absolutely nothing.

We strongly encourage 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 UPPER ransomware and to recover the data data totally free. Thus, the just best decision is to recover the lost information from the available backup.
