Kfuald – Ransomware

The Kfuald stands for a ransomware-type infection. Kfuald was elaborated specifically to encrypt all major file types. Once the file is encrypted people are not able to use them. Kfuald adds the “.kfuald” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Kfuald, will be renamed into “myphoto.jpg.kfuald“. As soon as the encryption is completed, Kfuald places a special text file into every folder containing the encrypted data.

The message given by Kfuald text file asking for the ransom is definitely the same as the statements given by other ransomware representatives. It actually mentions that the info is encrypted which the only way to bring back it is to use a an unique decryption key. Regretfully, this is absolutely true. The type of cryptography mechanism used by Kfuald is still not appropriately examined. Still, it is definitely particular that each victim might be given the specific decryption key, which is completely unique. It is impossible to restore the files without the key available.

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

Nonetheless, irrespective of the asked for quantity, people should keep away from paying the virus. Cyber frauds are not fair, so they tend to entirely disregard 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 outcome and people just lose their money for absolutely nothing.

We strongly recommend that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Kfuald ransomware and to recover the information data free of charge.
