Erif Virus – Details
Erif is a malicious software application functioning as typical ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.
Erif was created for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is successfully achieved, the users are not able to get access to them. Erif ransomware includes its own “.erif” to all the encrypted data. For example, the file “price_list.xls”, once modified by Erif, will be entitled as “price_list.xls.erif”. Once the encryption is achieved, Erif puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The message stated by document asking for the random os very comparable to the alerts given by other ransomware risks coming from the DJVU family. The warning essentially indicates that the data has been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.
The technique to encrypt the files used by Erif is not totally investigated. However, there is no doubt that each computer owner might be issued an unique decryption key, which is definitely special. It is incredibly hard to recuperate the data without the appropriate type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Erif virus 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 criminals who have actually released the Erif infection into the world wide web. In order to acquire the key and bring back the important information, the users are told to contact the frauds through email or by telegram and to pay the ransom in the quantity of $980.
The message likewise states that the people need to contact the Erif authors within 72 hours upon the moment of the data encryption. The alert suggests that by doing so individuals will get a 50% discount, therefore, the ransom quantity falls to $490.
No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no warranty that these online scoundrels will keep their pledges, so they may not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts.

Similarly, we urge you not to contact the frauds as they advise. Do not transfer loan into their wallets. There are no applications that could break the Erif virus or restore the data at no cost. Therefore, the only appropriate choice is to bring back the information from possible backups (if readily available).
