.ROKKU File

The rokku file extension is infamously associated with a ransomware labeled as Rokku that is distributed via e-mails, encrypts users files and them demands ransom in bitcoins for their recovery.

This particular ransomware was encountered in late march 2016 and is special in the fact that it has unique key for each encrypted file.

How to open:

Such files can only be accessed again and recovered when you pay the ransom in bitcoins. You can also wait until new decrypter is made and available for public.

How to convert:

You cannot convert or recover .rokku files without some decryption utility.
