Irjg Virus Ransomware

Irjg is a destructive software functioning as typical ransomware. Michael Gillespie, the popular virus researcher, first found this new name in the DJVU ransomware family.

Irjg was developed for the sole purpose to encrypt all popular file types. Rationally, as soon as the file encryption is successfully achieved, the users are unable to get access to them. Irjg ransomware adds its own “.irjg” to all the encrypted data. For instance, the file “price_list.xls”, once crypted by Irjg, will be entitled as “price_list.xls.irjg”. Once the encryption is accomplished, Irjg puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The alert mentioned by text file requesting the random os really similar to the notices given by other ransomware hazards coming from the DJVU family. The caution essentially shows that the files have been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is definitely true.

The method to encrypt the files used by Irjg is not totally looked into. However, there is no doubt that each computer owner may be released an unique decryption key, which is definitely unique. It is incredibly hard to recuperate the information without the suitable type in place.

“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 Irjg ransomware 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 introduced the Irjg ransomware into the world wide web. In order to get the key and bring back the crucial information, the users are told to connect with the scams through email or by telegram and to pay the ransom in the amount of $980.

The message likewise says that the people should call the Irjg authors within 72 hours upon the moment of the data file encryption. The alert shows that by doing so the people will acquire a 50% discount rate, for that reason, the ransom amount drops down 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 criminals will keep their promises, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. For this reason, paying ransom frequently does not result in a successful healing. So, the users may merely lose their money for nothing.

Similarly, we prompt you not to get in touch with the frauds as they instruct. Do not move money into their wallets. There are no applications that could break the Irjg virus or bring back the data at no charge. Therefore, the only proper choice is to bring back the data from possible backups (if readily available).
