Sounds a little more like someone "threw a cinder block through a window" and then climbed in, wandered around the office until they found the records room, found a way to pry the locks open on the filing cabinets, and then stayed there for a few months to pass files out the window one at a time. But nobody noticed the broken glass, no one saw any evidence that the records rooms were opened when they shouldn't have been, and nobody saw the hundred million files headed out the window? I understand this could have happened to anyone, but I don't expect the sec ops at a credit reporting agency to be average.
