Uyro Virus – Details

Uyro is a harmful software working as common ransomware. Michael Gillespie, the well-known virus researcher, very first found this new name in the DJVU ransomware family.

Uyro was created for the sole function to encrypt all popular file types. Realistically, as quickly as the encryption is effectively accomplished, the users are not able to get access to them. Uyro virus adds its own “.uyro” to all the encrypted files. For example, the file “price_list.xls”, once crypted by Uyro, will be entitled as “price_list.xls.uyro”. As soon as the encryption is achieved, Uyro puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.

The alert specified by document requesting the random os very similar to the notifications given by other ransomware threats belonging to the DJVU family. The caution generally indicates that the files have been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely true.

The approach to secure the files utilized by Uyro is not completely researched. However, there is no doubt that each computer owner might be released a special decryption key, which is absolutely special. It is extremely hard to recuperate the information without the proper type in location.

“Don’t worry, you can return all your files!”, from _readme.txt message:

Don't worry, you can return all your files! virus

One more peculiarity of the Uyro infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have actually introduced the Uyro ransomware into the web. In order to obtain the key and bring back the crucial information, the users are told to connect with the frauds via e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise states that individuals must contact the Uyro authors within 72 hours upon the moment of the information file encryption. The alert suggests that by doing so the people will acquire a 50% discount, therefore, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we highly recommend that you do not pay the ransom. There is no warranty that these online crooks will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom typically does not lead to a successful healing. So, the users might simply lose their money for absolutely nothing.

Similarly, we prompt you not to contact the scams as they advise. Do not transfer money into their wallets. There are no applications that could crack the Uyro virus or bring back the information at no charge. For that reason, the only correct choice is to restore the data from possible backups (if offered).
