Remove Crabs Virus (+Decrypt .crabs files) – Scarab Ransomware

Crabs Virus Ransomware

The Crabs stands for a ransomware-type infection. The virus comes from the Scarab ransomware family. Crabs was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Crabs adds the “.crabs” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Crabs, will be renamed into “myphoto.jpg.crabs“. As soon as the encryption is finished, Crabs places a special text file into every folder containing the encrypted data.

The message given by Crabs text file requesting the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the Scarab clan. It actually points out that the info is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by Crabs is still not correctly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is totally unique. It is difficult to bring back the files without the key available.

Another technique of Crabs is that the victims cannot get to the key. The key is saved on a particular server run by the frauds associated with Crabs ransomware. To get the key and recover the important information people have to pay the ransom.

Nevertheless, irrespective of the asked for quantity, people must stay away from paying the virus. Cyber frauds are not fair, 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 typically 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 certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Crabs ransomware and to recover the information data for free. Therefore, the just right decision is to recover the lost information from the available backup.
