One more peculiarity of the Dkrf infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the crooks who have introduced the Dkrf infection into the world wide web. In order to acquire the key and bring back the important data, the users are informed to contact the scams via e-mail or by telegram and to pay the ransom in the quantity of $980.
The message also says that individuals ought to contact the Dkrf authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so the people will acquire a 50% discount rate, therefore, the ransom amount drops down to $490.
