Rigj was developed 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. Rigj ransomware includes its own “.rigj” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Rigj, will be entitled as “price_list.xls.rigj”. When the encryption is achieved, Rigj puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by _readme.txt asking for the random os extremely comparable to the notifications given by other ransomware threats belonging to the DJVU family. The warning essentially shows that the information has been secured and the only solution to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely true.
The technique to secure the files used by Rigj is not completely looked into. Nevertheless, there is no doubt that each computer owner may be released a special decryption key, which is absolutely unique. It is very difficult to recover the data without the appropriate key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Rigj ransomware is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have introduced the Rigj ransomware into the web. In order to obtain the key and bring back the crucial information, the users are informed to get in touch with the frauds via email or by telegram and to pay the ransom in the amount of $980.
