Classified Computer Network

The CIA's insistence that it did not spy on its US Senate overseers collapsed Thursday with the release of a stark report by the agency's internal watchdog documenting improper computer surveillance and obstructionist behavior by CIA officers.

The White House has confirmed its computer system was targeted in a cyber attack, but the effort was thwarted and no classified networks were compromised.

The White House acknowledged on Monday that one of its computer networks was hit by a cyber attack, but said there was no breach of any classified systems and no indication any data was lost.
