Criminals are cold-hearted and do not provide a private key only from a good will. Victims have to pay 0.3 Bitcoins (almost $200) using Tor browser. What is interesting, hackers give a quite extended deadline for making a transaction. Victims have to transfer money within 30 days; usually, the time limit varies from 12 to 72 hours.
