Doubts remain on North Korea role in Sony attack

CONSPIRACIES ABOUND: A number of cybersecurity specialists argue that links to North Korea are uncertain, and that some evidence leads elsewhere.

President Barack Obama earlier this month took the unusual step of naming North Korea for the crippling attack, while promising that the United States would “respond proportionately” after the FBI said evidence pointed to Pyongyang.
