Ygkz was created for the sole purpose to encrypt all popular file types. Realistically, as soon as the encryption is successfully accomplished, the users are unable to get access to them. Ygkz ransomware adds its own “.ygkz” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Ygkz, will be entitled as “price_list.xls.ygkz”.

The message mentioned by document asking for the random os very comparable to the alerts given by other ransomware threats coming from the DJVU family. The warning essentially indicates that the information has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.
