Bitcoin Ransom

DDoS extortion is actually not a brand new trick by the hacker group, however there have been a number of new developments to it. Notable amongst them is the usage of Bitcoin as a technique of payment. DD4BC (DDoS for Bitcoin) is a hacker (or hacker group) who has been discovered to extort victims with DdoS assaults, demanding payment by way of Bitcoin.

In November 2014, studies emerged of the group having despatched a notice to the Bitalo Bitcoin trade demanding 1 Bitcoin in return for serving to the location improve its safety towards DDoS assaults.
