They know now

The WashPost on the theft of data on 26.5-million veterans, quotes Veterans Affairs Secretary Jim Nicholson:

"They believe this was a random burglary and not targeted at this data," he said. "There have been a series of burglaries in that community. . . . There is no indication at all that any use is being made of this data or even that they know that they have it."

If the thieves didn't know what they had before, they certainly do now.
