A few weeks ago, I told you that hackers had managed to infiltrate White House networks last year. The hackers only managed to crack into the unclassified computer system, but now we know that they still got their hands on some very sensitive information, including emails to and from the President.
But officials have conceded that the unclassified system routinely contains much information that is considered highly sensitive: schedules, email exchanges with ambassadors and diplomats, discussions of pending personnel moves and legislation, and, inevitably, some debate about policy.
As far as we know right now, it seems that the hackers didn't manage to break into the President's email account. Instead, they accessed email archives related to other White House accounts. From these accounts it is likely that the hackers were able to collect emails sent and received by the President during his communications with those accounts.
