Well, well. The New York Times is reporting that the penny may have finally dropped in Washington:

WASHINGTON — American officials are concerned that the Chinese government could use the stolen records of millions of federal workers and contractors to piece together the identities of intelligence officers secretly posted in China over the years.

The potential exposure of the intelligence officers could prevent a large cadre of American spies from ever being posted abroad again, current and former intelligence officials said. It would be a significant setback for intelligence agencies already concerned that a recent data breach at the Office of Personnel Management is a major windfall for Chinese espionage efforts.
