Considering the number of "IT Professionals" who seemingly can't get something as basic as updating their DNS servers to non-compromisable versions correct (that number is more than astounding given all the press about a problem in DNS last year which every major supplier corrected), there is no doubt we will learn of other such stories.
Were I ever to become a criminal and of a mind to attack infrastructure, I would follow a Google "signs of quality" approach in begining the process. If certain companies cannot even get their basics right, they are clearly the kind of operation I would look at targeting.
The Russian crime gangs employ some very bright folks who are very good at what they do. There are others who are even better (in that they are capable of compromises without even leaving much of a footprint at all).
In this declining economy, you can bet there will be far more of this kind of activity as IT budgets get cut and people get stretched too thin. You will also see more stories of individual people being duped as they grasp for deals and life lines, falling for scams and fraudsters. All I can say is it is getting to be a far less "kinder and gentler" world out there, so watch your infrastructure carefully.
