Remove Bdev Virus (.[bad_dev@tuta.io].bdev Files Ransomware) – Dharma Ransomware

Bdev Virus Ransomware

The Bdev stands for a ransomware-type infection. The virus comes from the Dharma ransomware family. Bdev was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Bdev adds the “.[bad_dev@tuta.io].bdev” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Bdev, will be renamed into “myphoto.jpg.[bad_dev@tuta.io].bdev“. As quickly as the encryption is finished, Bdev places a special text file into every folder containing the encrypted data.

The message given by Bdev text file asking for the ransom is absolutely the same as the statements given by other ransomware representatives coming from the Dharma family. It actually points out that the info is encrypted which the only way to restore it is to use a a special decryption key. Unfortunately, this is absolutely true. The sort of cryptography mechanism applied by Bdev is still not correctly examined. Still, it is definitely particular that each victim may be given the specific decryption key, which is completely unique. It is difficult to restore the files without the key available.

Another technique of Bdev is that the victims cannot get to the key. The key is saved on a particular server run by the frauds associated with Bdev ransomware. To get the key and recover the important info people have to pay the ransom.

However, irrespective of the requested quantity, people need to stay away from paying the virus. Cyber frauds are not fair, so they tend to completely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom normally does not give any positive outcome and people simply lose their money for absolutely nothing.

We strongly encourage that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Bdev ransomware and to recover the data data for free. Hence, the only best decision is to recover the lost data from the available backup.
