"Now in the middle of 2015, yet another group has put its own spin on this tried and true method of network disruption. As analyzed by Heimdal Security Software, a group of computer criminals known as ‘DD4BC’ is threatening targets with massive DDoS attacks unless they pay a ransom using Bitcoins. These attacks generally bring down vital business services and cause disruption and financial loss. "
DD4BC DDoS Extortion Threat Activity
For the last year or so, an individual or organization calling itself DD4BC (‘DDoS for Bitcoin’) has
been rapidly increasing both the frequency and the scope of its DDoS extortion attempts, shifting
target demographics from Bitcoin exchanges to online casinos and betting shops and, most recently,
to prominent financial institutions (banks, trading platforms, payment acquirers) across the United
States, Europe, Asia, Australia, and New Zealand.
