Or you know these 'hackers' could have just watched CNN. For some reason this story seems pretty farfetched.
As an example, presumably Obama has various advisors on foreign policy, and they'll disagree. Some of them will advocate taking a harder line with (say) Russia, while others will advocate a softer line. If I were Russian intelligence I'd want to know who was who, so I could keep track of those advisors if and when they move into positions within the next administration.
