Credo Virus – Details

The Credo mean a ransomware-type infection. The virus comes from the Dharma ransomware family. Credo was elaborated particularly to encrypt all major file types. Once the file is encrypted people are unable to use them. Credo adds the “.[Recovery@qbmail.biz].credo” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Credo, will be renamed into “myphoto.jpg.[Recovery@qbmail.biz].credo“. As quickly 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 requesting for the ransom is definitely the same as the statements given by other ransomware representatives belonging to the Dharma clan. It literally points out that the info is encrypted which the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true. The sort of cryptography mechanism applied by Credo is still not properly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is absolutely distinct. It is impossible to restore the files without the key available.

Another trick of Credo is that the victims cannot get to the key. The key is stored on a specific server run by the frauds connected with Credo ransomware. To get the key and recover the important information people need to pay the ransom.

However, regardless of the asked for amount, people need to stay away from paying the virus. Cyber frauds are unfair, so they tend to totally disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive result and people just lose their money for absolutely nothing.

We highly encourage that you do not contact these crooks and absolutely 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 totally free. Thus, the just best decision is to recover the lost data from the available backup.
