Remove Caterpillar Virus (.Caterpillar Files Ransomware) – VoidCrypt Ransomware

Caterpillar Virus – Details

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

The message given by Caterpillar text file requesting for the ransom is absolutely the same as the statements given by other ransomware representatives coming from the VoidCrypt type. It actually mentions that the info is encrypted and that the only way to restore it is to use a a distinct decryption key. Sadly, this is definitely true. The type of cryptography mechanism used by Caterpillar is still not appropriately examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.

Another technique of Caterpillar is that the victims cannot gain access to the key. The key is stored on a particular server run by the frauds related to Caterpillar ransomware. To get the key and recover the important information people have to pay the ransom.

Nevertheless, regardless of the requested quantity, people must stay away from paying the ransom. Cyber frauds are unfair, so they tend to completely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom typically does not give any positive result and people simply waste their money for nothing.

We highly recommend 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 Caterpillar ransomware and to recover the information data for free. Thus, the only best decision is to recover the lost data from the available backup.
