Qepi Virus – Details

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

Qepi was created for the sole function to encrypt all popular file types. Realistically, as soon as the file encryption is effectively accomplished, the users are not able to get access to them. Qepi virus adds its own “.qepi” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Qepi, will be entitled as “price_list.xls.qepi”. As soon as the file encryption is achieved, Qepi puts its own special text document (_readme.txt) into all the folders that store the encrypted files.

The message mentioned by document asking for the random os really comparable to the notifications offered by other ransomware hazards coming from the DJVU family. The caution essentially indicates that the data has been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.

The approach to encrypt the files utilized by Qepi is not totally investigated. However, there is no doubt that each computer owner might be issued a special decryption key, which is absolutely special. It is extremely tough to recuperate the information without the appropriate type in place.

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

message from Qepi virus

One more peculiarity of the Qepi infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have actually released the Qepi infection into the web. In order to obtain the key and bring back the important information, the users are told to connect with the scams through email or by telegram and to pay the ransom in the amount of $980.

The message likewise says that individuals should call the Qepi authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so the people will obtain a 50% discount, for that reason, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we strongly recommend that you do not pay the ransom. There is no guarantee that these online crooks will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts.

Similarly, we prompt you not to contact the scams as they advise. Do not transfer loan into their wallets. There are no applications that could split the Qepi virus or restore the information for free. For that reason, the only right decision is to bring back the data from possible backups (if offered).
