Eeyu – Ransomware
Eeyu is a malicious software working as common ransomware. Michael Gillespie, the well-known malware researcher, very first discovered this new name in the DJVU ransomware family.
Eeyu was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively accomplished, the users are not able to get access to them. Eeyu virus adds its own “.eeyu” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Eeyu, will be titled as “price_list.xls.eeyu”. When the encryption is accomplished, Eeyu puts its own special text file (_readme.txt) into all the folders that save the encrypted files.
The message stated by _readme.txt asking for the random os extremely similar to the notifications given by other ransomware hazards belonging to the DJVU family. The caution generally indicates that the data has been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.
The approach to secure the files utilized by Eeyu is not completely researched. Nevertheless, there is no doubt that each computer owner may be provided a special decryption key, which is absolutely distinct. It is extremely tough to recuperate the information without the suitable key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Eeyu virus 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 actually released the Eeyu virus into the web. In order to obtain the key and restore the crucial information, the users are told to get in touch with the scams via email or by telegram and to pay the ransom in the quantity of $980.
The message likewise says that the people should contact the Eeyu authors within 72 hours upon the moment of the data encryption. The alert indicates that by doing so individuals will get a 50% discount rate, for that reason, the ransom amount drops down to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their promises, 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. For this reason, paying ransom frequently does not lead to a successful recovery. So, the users might merely lose their money for absolutely nothing.
Likewise, we advise you not to call the scams as they advise. Do not move money into their wallets. There are no applications that might split the Eeyu virus or bring back the information at no charge. Therefore, the only appropriate decision is to bring back the information from possible backups (if offered).
