Efvc Virus – Details

Efvc is a destructive software functioning as common ransomware. Michael Gillespie, the popular virus researcher, very first found this new name in the DJVU ransomware family.

Efvc was developed for the sole function to encrypt all popular file types. Logically, as quickly as the encryption is effectively achieved, the users are unable to get access to them. Efvc ransomware adds its own “.efvc” to all the encrypted files. For example, the file “price_list.xls”, when crypted by Efvc, will be entitled as “price_list.xls.efvc”. As soon as the encryption is achieved, Efvc puts its own special text file (_readme.txt) into all the folders that save the encrypted files.

The message mentioned by document requesting for the random os extremely comparable to the alerts provided by other ransomware risks coming from the DJVU family. The warning generally indicates that the files have been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely real.

The technique to secure the files utilized by Efvc is not completely researched. However, there is no doubt that each computer owner might be issued a special decryption key, which is absolutely unique. It is exceptionally hard to recover the information without the proper key in location.

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

One more peculiarity of the Efvc ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the criminals who have actually released the Efvc ransomware into the internet. In order to get the key and restore the crucial information, the users are told to contact the frauds via email or by telegram and to pay the ransom in the amount of $980.

The message also says that the people should get in touch with the Efvc authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so the people will get a 50% discount rate, therefore, the ransom quantity drops down to $490.

There is no guarantee that these online criminals will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Hence, paying ransom typically does not lead to a successful healing. So, the users might merely lose their money for nothing.

There are no applications that might crack the Efvc ransomware or bring back the data for free. Therefore, the only correct choice is to restore the information from possible backups (if offered).
