In the email, the group had written that unless Delport immediately paid 1 Bitcoin ($610) to the address show, she would face 10-300 Gbps DDoS attack the next day. The crooks also warned that if the DDoS had already started and the victim decides she wanted them to stop, the ransom would jump to 20 Bitcoin ($12,150).
Such attacks were first seen last year when a group named DD4BC started using them. This group, however, was arrested by Europol last winter but many other wannabes appeared following their steps. This includes Armada Collective, who`s most lucrative hit was against ProtonMail, when the email provides was forced to pay $6,000 to avoid a huge DDoS attack.
