Bora Virus Removal Guide (+Decrypt .bora files)

Bora Virus – Details

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

Bora was developed for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is successfully achieved, the users are unable to get access to them. Bora virus includes its own “.bora” to all the encrypted files. For example, the file “price_list.xls”, once modified by Bora, will be titled as “price_list.xls.bora”. As soon as the file encryption is accomplished, Bora puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.

The message specified by _readme.txt asking for the random os really comparable to the notices offered by other ransomware risks belonging to the DJVU family. The caution basically indicates that the data has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The method to secure the files utilized by Bora is not totally looked into. However, there is no doubt that each computer system owner may be issued a special decryption key, which is definitely unique. It is exceptionally difficult to recover the information without the appropriate type in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

Don't worry, you can return all your files! virus

One more peculiarity of the Bora 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 crooks who have actually introduced the Bora ransomware into the world wide web. In order to get the key and restore the important information, the users are informed to connect with the scams via e-mail or by telegram and to pay the ransom in the amount of $980.

The message also states that the people need to get in touch with the Bora authors within 72 hours upon the minute of the data file encryption. The alert shows that by doing so the people will obtain a 50% discount rate, therefore, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we strongly advise that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts. For this reason, paying ransom typically does not result in a successful recovery. So, the users might simply lose their money for nothing.

Similarly, we advise you not to contact the frauds as they advise. Do not move loan into their wallets. There are no applications that could break the Bora virus or bring back the information at no cost. For that reason, the only right decision is to bring back the information from possible backups (if offered).
