Since April of 2015, there have been discussions about the cyber attacks by the DDoS gang. They are called the DD4BC group and they are responsible for 114 attacks by DDoS on Akamai customers. Akamai is a leading content delivery network (CDN) for the delivery of media and software, and cloud security solutions which gives businesses fast, reliable, and secure Internet service. The DDoS group tries to extort money from successful companies which depend on the Internet. They threaten to knock their internet presence out with major DDoS (denial of service attacks).
The group started during September of 2014. Their biggest attack was more than 56.2 gbps of online traffic. They hit their peak in June of 2015 and were hitting more targets than they were in previous months. Those initiating the threats send huge volumes of unimportant traffic to their targets to overwhelm their systems. This is all in the attempts to knock out websites or make them inaccessible to others from outside the company.
How do they work this? They first contact their target and explain they will have a lower level of the DDoS threats if they pay a ransom by a certain time. If the target ignores the communication or email of the proposed threat, larger attacks would be threatened and the targets are requested to pay even larger ransoms.
This group is very dangerous and they are destroying companies. They continue to increase the amount of threats and continue to target major companies with the hopes of greater gains.
