I had been made aware of this earlier, as my brother was involved to a degree.
bunch of articles with his views:
What is shared from his perspective, is they are suppose to be the litmus test, and Gold standard for PCI compliance.
Also their efforts to delay and hide this info.
In short, what has been shared, is really the tip of a major problem in internet security, that not only includes this but much much more, and we, the public, are not hearing but around 10% of the problems.
Its much more, than our individual identities, and what I am allowed to hear, is downright scary...
Nothing we can do, but you might see some major stories coming shortly, if they chose to release this info.
