UNPRECEDENTED: US National Intelligence man says the Sony hack was the most serious ever.

NEW YORK: US director of National Intelligence James Clapper said the recent cyber attack against Sony Pictures, which Washington has blamed on North Korea, is the most serious such attack ever against US interests.
