According to PLXsert, DD4BC recently threatened to expose targeted organizations via social media, adding to the damage caused by the DDoS attack itself.

Prolific bitcoin extortion group DD4BC has ramped up the rate of its attacks over 2015, using new social tactics specifically in order to trap and tarnish the reputation of financial services companies.

Meanwhile, a number of companies have given up on DD4BC’s demands, but one former victim tried a different strategy and placed a bounty of 100 bitcoins on the group with the hope that someone might come out with information that would lead to the identification or even arrest of the perpetrators. The group then demands a Bitcoin ransom to protect the company from a larger attack which would crash the site.

The attacks have been measured at up to 50 Gbps, rising from the 15-20 Gbps observed in May; this is lower than the group claims.

Most of their attacks targetted Akamai clients operating in the financial sector, where there are higher chances of extracting a Bitcoin payment when compared to other industries.

“DD4BC has been using the threat of DDoS attacks to secure Bitcoin payments from its victims for protection against future attacks”, said Stuart Scholly, Senior Vice President General Manager, Security Division at Akamai.

Akamai report reveals an increase in DDoS attacks in 2015.

Attack methodology by the group is usually via use of multi-vector DDoS attack campaigns, including Layer 7 DDoS in multi-vector attacks,
