Credo – General Info

The Credo mean a ransomware-type infection. The virus comes from the Dharma ransomware family. Credo was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are not able to use them. Credo adds the “.[Recovery@qbmail.biz].credo” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Credo, will be renamed into “myphoto.jpg.[Recovery@qbmail.biz].credo“. As soon as the encryption is finished, Credo places a special text file into every folder containing the encrypted data.

The message given by Credo text file asking for the ransom is definitely the like the statements given by other ransomware representatives belonging to the Dharma family. It actually mentions that the info is encrypted and that the only way to restore it is to use a a special decryption key. Unfortunately, this is absolutely true. The sort of cryptography mechanism used by Credo is still not appropriately examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is absolutely unique. It is impossible to bring back the files without the key available.

Another technique of Credo is that the victims cannot access to the key. The key is saved on a specific server run by the frauds related to Credo ransomware. To get the key and recover the important info people have to pay the ransom.

Nonetheless, regardless of the asked for quantity, people must stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to totally ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people just waste their money for nothing.

We strongly recommend 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 Credo ransomware and to recover the information data for free. Therefore, the only right decision is to recover the lost data from the available backup.
