The White House can't figure out the source of the massive JPMorgan cyberattack — and that's a problem

Last week, it was revealed that JPMorgan Chase had been the victim of a massive cyberattack back in July that affected 76 million household accounts. Yet three months after the breach, the White House still cannot pinpoint a source or motive for the hacks, The New York Times reported Wednesday. This comes despite new efforts to inform top national security officials about major cyberattacks, which has led to President Obama and certain advisers receiving "periodic briefings" on such cases.
