A new Ransomware-as-a-Service called Jokeroo is being promoted on underground hacking sites and via Twitter. The RaaS allows affiliates to allegedly gain access to a fully functional ransomware and payment server. In order to become an affiliate a would-be criminal has to pay to join a particular membership package. These packages range from $90 USD, where the affiliate earns 85% of the ransom payments, to $300 and $600 packages where the affiliates keep all of the revenue.
