Rugj Virus Removal Guide (+Decrypt .rugj files)

Rugj – Ransomware

Rugj is a destructive software working as typical ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Rugj was created for the sole function to encrypt all popular file types. Logically, as soon as the encryption is effectively accomplished, the users are unable to get access to them. Rugj ransomware adds its own “.rugj” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Rugj, will be titled as “price_list.xls.rugj”. Once the encryption is achieved, Rugj puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by _readme.txt asking for the random os really comparable to the alerts provided by other ransomware threats belonging to the DJVU family. The warning essentially shows that the information has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The method to encrypt the files used by Rugj is not completely researched. However, there is no doubt that each computer owner may be released an unique decryption key, which is absolutely distinct. It is exceptionally hard to recover the data without the proper key in place.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Rugj infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have actually released the Rugj virus into the internet. In order to get the key and restore the important information, the users are told to get in touch with the scams by means of email or by telegram and to pay the ransom in the amount of $980.

The message likewise states that individuals ought to get in touch with the Rugj authors within 72 hours upon the minute of the information encryption. The alert indicates that by doing so individuals will get a 50% discount rate, therefore, the ransom quantity falls to $490.

No matter what the amount of the ransom is, we highly advise that you do not pay the ransom. There is no guarantee that these online crooks will keep their promises, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom often does not result in a successful healing. So, the users might merely lose their money for nothing.

Likewise, we advise you not to call the scams as they instruct. Do not move cash into their wallets. There are no applications that could split the Rugj ransomware or bring back the data at no cost. Therefore, the only right decision is to restore the information from possible backups (if available).
