Cyber attacks rendering large corporations helpless is no longer just a movie storyline, it is stuff that CEO nightmares are made of. One such nightmare, especially for the financial sector, is DD4BC. As this blog by Akamai explains, DD4BC informs victims that they will launch a DDoS attack of 400-500 Gbps against them and demand ransom in Bitcoin. "Of late, they have been threatening exposure of targeted organizations via social media. Their goal is to publicly embarrass the company, thus harming its reputation and garner additional attention towards credibility for the service disruption. Their methodology has also changed in that they are utilizing multi-vector campaigns more readily as well as in some instances re-visiting previous targets that experienced some level of impact during the initial event. We have also observed this group incorporating a Layer 7 attack as part of the multi-vector attack," informs the blog.
