Epor Virus Ransomware

Epor is a malicious software functioning as common ransomware. Michael Gillespie, the well-known malware researcher, very first discovered this new name in the DJVU ransomware family.

Epor was created for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is effectively achieved, the users are unable to get access to them. Epor virus adds its own “.epor” to all the encrypted files. For instance, the file “price_list.xls”, as soon as crypted by Epor, will be titled as “price_list.xls.epor”. As soon as the file encryption is accomplished, Epor puts its own distinct text document (_readme.txt) into all the folders that keep the encrypted files.

The message mentioned by text file requesting the random os really comparable to the notices provided by other ransomware hazards coming from the DJVU family. The warning essentially indicates that the information has been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely true.

The technique to encrypt the files utilized by Epor is not entirely investigated. However, there is no doubt that each computer system owner might be issued a special decryption key, which is definitely unique. It is exceptionally difficult to recuperate the data without the suitable type in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Epor 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 Epor infection into the world wide web. In order to acquire the key and bring back the essential data, the users are informed to connect with the scams through email or by telegram and to pay the ransom in the quantity of $980.

The message also says that the people ought to get in touch with the Epor authors within 72 hours upon the moment of the data encryption. The alert suggests that by doing so individuals will obtain a 50% discount rate, therefore, the ransom quantity drops down to $490.

No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no warranty that these online crooks will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom often does not lead to an effective healing. So, the users may simply lose their money for nothing.

Similarly, we urge you not to call the frauds as they advise. Do not move loan into their wallets. There are no applications that could break the Epor virus or bring back the data for free. Therefore, the only appropriate decision is to restore the information from possible backups (if available).
