The CHEKYSHKA stands for a ransomware-type infection. CHEKYSHKA was elaborated particularly to encrypt all major file types. Once the file is encrypted people are unable to use them. CHEKYSHKA adds the “.chekyshka” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by CHEKYSHKA, will be renamed into “myphoto.jpg.chekyshka“. As soon as the encryption is completed, CHEKYSHKA places a special text file into every folder containing the encrypted data.The message given by CHEKYSHKA text file asking for the ransom is definitely the like the statements given by other ransomware representatives. It actually points out that the information is encrypted and that the only way to restore it is to use a a distinct decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism used by CHEKYSHKA is still not appropriately examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is totally distinct. It is difficult to bring back the files without the key available.
Another technique of CHEKYSHKA is that the victims cannot get to the key. The key is kept on a particular server run by the frauds related to CHEKYSHKA ransomware. To get the key and recover the important information people have to pay the ransom.
