Bitcoin Extortion Group DD4BC Now Targeting Financial Services

An anonymous reader writes: Akamai is detailing the activities of DD4BC, a cyber-extortionist group that has launched distributed denial-of-service (DDoS) attacks against numerous organizations and demanded Bitcoin payments to stop the attacks. The group is sending ransom emails requiring payments of 25 to 100 Bitcoin, which is about $6,000 — $24,000 (€5,350 — €21,400). Social media shaming is also part of the deal, threatening to expose the DDOS on Twitter if payment is not made.
