This is bad but not so bad for CIA HUMINT. Most* human source handlers, at least from what I've read, work under Official Cover. That is, they work at the embassy under their real name. This way if they get caught they have diplomatic immunity and can't be charged as spies. Foreign governments know that people that work at the embassy are often spies and generally the know which ones are spies (used to be the case that the passport officer was almost always a spy). Not that this won't hurt, but it won't be a death blow. The real danger comes from the fact that handlers, and more importantly their superiors, are vulnerable to blackmail because OPM stored VERY personal information (affairs, drug addictions, etc...). * CIA does have Non-Official Cover personel (NOC), this will hurt them more. Then again fingerprint readers are not impossible to fool and even before the OPM hack NOCs were facing increasing exposure risk due to biometrics.
