Epub Virus Ransomware
Epub is a destructive software working as common ransomware. Michael Gillespie, the widely known virus researcher, first discovered this new name in the DJVU ransomware family.
Epub was created for the sole purpose to encrypt all popular file types. Realistically, as soon as the encryption is effectively achieved, the users are unable to get access to them. Epub ransomware adds its own “.epub” to all the encrypted data. For instance, the file “price_list.xls”, when modified by Epub, will be titled as “price_list.xls.epub”. Once the file encryption is achieved, Epub puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by _readme.txt requesting for the random os really comparable to the notices provided by other ransomware threats coming from the DJVU family. The warning generally shows that the data has been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is absolutely true.
The approach to secure the files used by Epub is not entirely looked into. Nevertheless, there is no doubt that each computer system owner may be released an unique decryption key, which is definitely distinct. It is incredibly tough to recuperate the information without the suitable type in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Epub 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 total control by the scoundrels who have released the Epub infection into the world wide web. In order to acquire the key and bring back the crucial data, the users are told to get in touch with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.
The message also states that the people need to call the Epub authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so the people will get a 50% discount rate, therefore, the ransom amount falls to $490.
