Now that many U.S. intelligence and cybersecurity experts have concluded that North Korea was behind the devastating digital attack against Sony, the question is: What can the U.S. government do about it?
If North Korea is conclusively proven to be behind the attack—the matter is still officially under investigation—the United States should respond, private sector and government officials told CNBC. There's no general agreement, however, on what an effective retaliation would look like. Additionally, experts said any successful measure will need to reach Pyongyang's well-insulated elite, rather than just harming the already suffering majority.
The strategy with the most potential, experts said, would involve leaning on outside entities, whether they be foreign firms such as telecom companies or overseas governments like the one in Beijing.
