Boop Virus Removal Guide (+Decrypt .boop files)

Boop Virus – Details

Boop is a malicious software application functioning as common ransomware. Michael Gillespie, the widely known virus researcher, first found this new name in the DJVU ransomware family.

Boop was created for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is successfully accomplished, the users are unable to get access to them. Boop ransomware includes its own “.boop” to all the encrypted data. For instance, the file “price_list.xls”, when crypted by Boop, will be entitled as “price_list.xls.boop”. Once the encryption is accomplished, Boop puts its own unique text file (_readme.txt) into all the folders that save the encrypted files.

The message mentioned by _readme.txt requesting the random os very similar to the alerts offered by other ransomware risks coming from the DJVU family. The caution essentially shows that the data has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is definitely real.

The technique to encrypt the files used by Boop is not entirely investigated. However, there is no doubt that each computer system owner might be provided a special decryption key, which is absolutely special. It is very hard to recover the data without the appropriate type in place.

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

message from Boop virus

One more peculiarity of the Boop 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 scoundrels who have released the Boop virus into the web. In order to obtain the key and bring back the crucial information, the users are told to connect with the scams via email or by telegram and to pay the ransom in the quantity of $980.

The message also states that individuals ought to call the Boop authors within 72 hours upon the moment of the data encryption. The alert indicates that by doing so individuals will acquire a 50% discount, for that reason, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no assurance that these online crooks will keep their pledges, 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. Hence, paying ransom frequently does not result in a successful recovery. So, the users might just lose their money for nothing.

Similarly, we prompt you not to call the scams as they advise. Do not transfer loan into their wallets. There are no applications that could split the Boop ransomware or restore the information at no cost. For that reason, the only appropriate choice is to restore the data from possible backups (if offered).
