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.
