OurMine Team Attack Exceeded 117 Gbps

A new hacking group has landed on the Akamai's PLXsert and CSIRT radar for taking responsibility for launching DDoS attacks against several of our customers in the financial services sector.

The entity calls itself the "OurMine Team" and if it is to be believed, it has gained access to one customer's $500,000 account. The group has announced it will give that money to the poor.

This is a relatively new group, which started its Twitter account March 31, 2015. Before it started targeting the financial sector, the group generally discussed and conducted DDoS attacks against gaming services.

Akamai researchers validated several DDoS attacks targeted against financial services customers, though Akamai has so far been able to protect them and prevent outages.

In a post called "The Truth Behind Team OurMine," the Drama Alert blog estimated that OurMine consists of 3-5 people, all from Saudi Arabia, "which makes it very hard to find them."

Meanwhile, multiple groups have claimed to have doxed OurMine.

Social media campaigns 
The group is also taking to Twitter to stir the pot. In one tweet, OurMine announces it has targeted Soundcloud:
