Remove Caleb Virus (+Decrypt .[Unlockfiles@qq.com].Caleb files) – Phobos Ransomware

Caleb Virus – Details

The Caleb mean a ransomware-type infection. The infection comes from the Phobos ransomware family. Caleb was elaborated specifically to encrypt all major file types. Once the file is encrypted people are unable to use them. Caleb adds the “.[Unlockfiles@qq.com].Caleb” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Caleb, will be renamed into “myphoto.jpg.[Unlockfiles@qq.com].Caleb“. As quickly as the encryption is completed, Caleb places a special text file into every folder containing the encrypted data.

The message given by Caleb text file requesting for the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the Phobos family. It literally discusses that the info is encrypted and that the only way to restore it is to use a a distinct decryption key. Unfortunately, this is absolutely true. The sort of cryptography mechanism applied by Caleb is still not correctly examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is completely distinct. It is difficult to bring back the files without the key available.

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

Nevertheless, regardless of the requested amount, people need to keep away from paying the ransom. Cyber frauds are unfair, 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 provide any positive result and people simply waste their money for absolutely nothing.

We strongly advise 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 Caleb ransomware and to recover the information data free of charge. Hence, the just right decision is to recover the lost information from the available backup.
