Rastar Virus – Details
The Rastar stands for a ransomware-type infection. Rastar was elaborated specifically to encrypt all major file types. Once the file is encrypted people are unable to use them. Rastar adds the “.rastar” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Rastar, will be renamed into “myphoto.jpg.rastar“. As soon as the encryption is finished, Rastar places a special text file into every folder containing the encrypted data.The message given by Rastar text file requesting for the ransom is absolutely the like the statements given by other ransomware virus representatives. It literally discusses 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 sort of cryptography mechanism applied by Rastar is still not properly examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely distinct. It is difficult to restore the files without the key available.
Another technique of Rastar is that the victims cannot gain access to the key. The key is stored on a particular server run by the frauds related to Rastar ransomware. To get the key and recover the important info people have to pay the ransom.
