Wrui – Ransomware

Wrui is a malicious software working as common ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Wrui was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively achieved, the users are not able to get access to them. Wrui virus includes its own “.wrui” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Wrui, will be titled as “price_list.xls.wrui”. Once the file encryption is achieved, Wrui puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by text file asking for the random os really similar to the notices given by other ransomware risks coming from the DJVU family. The warning basically indicates that the data has been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely real.

The method to encrypt the files used by Wrui is not entirely looked into. Nevertheless, there is no doubt that each computer system owner might be released an unique decryption key, which is definitely special. It is incredibly hard to recuperate the data without the proper key in location.

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

One more peculiarity of the Wrui 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 criminals who have introduced the Wrui ransomware into the web. In order to obtain the key and bring back the crucial information, the users are told to get in touch with the scams via e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise states that the people need to call the Wrui authors within 72 hours upon the minute of the data encryption. The alert shows that by doing so individuals will acquire a 50% discount rate, for that reason, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we strongly recommend that you do not pay the ransom. There is no guarantee 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 amount of the ransom is gotten into their accounts. Thus, paying ransom typically does not lead to a successful healing. So, the users may just lose their money for nothing.

Likewise, we urge you not to get in touch with the frauds as they advise. Do not move cash into their wallets. There are no applications that might break the Wrui ransomware or bring back the information for free. Therefore, the only appropriate decision is to restore the data from possible backups (if offered).
