Michael S. Schmidt and David E. Sanger, reporting for the NYT:
Some of President Obama’s email correspondence was swept up by
Russian hackers last year in a breach of the White House’s
unclassified computer system that was far more intrusive and
worrisome than has been publicly acknowledged, according to senior
American officials briefed on the investigation.
The hackers, who also got deeply into the State Department’s
unclassified system, do not appear to have penetrated closely
guarded servers that control the message traffic from Mr. Obama’s
BlackBerry, which he or an aide carries constantly.
In 2009 it seemed forward-thinking that the president carried a BlackBerry. Now, it feels preposterously behind the times.
