Eyrv Virus – Details
Eyrv is a destructive software application functioning as typical ransomware. Michael Gillespie, the widely known malware researcher, first found this new name in the DJVU ransomware family.
Eyrv was created for the sole function to encrypt all popular file types. Realistically, as quickly as the encryption is successfully achieved, the users are unable to get access to them. Eyrv ransomware includes its own “.eyrv” to all the encrypted files. For example, the file “price_list.xls”, when modified by Eyrv, will be entitled as “price_list.xls.eyrv”. As soon as the file encryption is achieved, Eyrv puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.
The message mentioned by _readme.txt asking for the random os extremely comparable to the notifications offered by other ransomware hazards belonging to the DJVU family. The caution generally shows that the information has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is definitely true.
The method to encrypt the files utilized by Eyrv is not entirely looked into. However, there is no doubt that each computer system owner might be provided an unique decryption key, which is absolutely special. It is very hard to recover the data without the proper type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Eyrv infection 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 crooks who have actually released the Eyrv ransomware into the world wide web. In order to obtain the key and restore the important data, the users are told to get in touch with the frauds through email or by telegram and to pay the ransom in the quantity of $980.
The message also states that the people need to get in touch with the Eyrv authors within 72 hours upon the moment of the information file encryption. The alert indicates that by doing so individuals will obtain a 50% discount rate, therefore, the ransom amount falls to $490.
