Four Virus – DetailsThe Four stands for a ransomware-type infection. The virus comes from the Dharma ransomware family. Four was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Four adds the “.[email@example.com].four” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Four, will be renamed into “myphoto.jpg.[firstname.lastname@example.org].four“. As soon as the encryption is completed, Four places a special text file into every folder containing the encrypted data.
The message given by Four text file asking for the ransom is absolutely the like the statements given by other ransomware virus representatives belonging to the Dharma clan. It actually mentions that the info is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism applied by Four is still not appropriately examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is completely distinct. It is impossible to bring back the files without the key available.
Another technique of Four is that the victims cannot gain access to the key. The key is saved on a particular server run by the frauds connected with Four ransomware. To get the key and recover the important info people need to pay the ransom.
Nonetheless, irrespective of the requested quantity, people should keep away from paying the virus. Cyber frauds are not fair, so they tend to entirely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive result and people just lose their money for nothing.
We strongly 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 Four ransomware and to recover the data data totally free. Hence, the just best decision is to recover the lost information from the available backup.
