The U.S. government has called on North Korea to compensate Sony Pictures for the cyber attack that has cost the studio millions of dollars and crippled its operations. North Korea insists it was not behind the attack, but a State Department spokeswoman says that’s par for the course.

“The government of North Korea has a long history of denying responsibility for this destructive and provocative action,” Marie Harf said during a news conference today, “and if they want to help here, they can admit their culpability and compensate Sony for the damage they caused.” She did not elaborate, despite a reporter pressing for details.

Damage to the studio, and the losses it incurred from shelving the release of The Interview, is expected to top $100 million — possibly much more.

North Korea’s own meager Internet service, meanwhile, went dark on Monday in what experts say appears to have been a concerted attack. It remains unclear whether the U.S., which has vowed to take a “measured response” against North Korea for the Sony attack, was behind the collapse of North Korea’s Internet service.

Harf today also downplayed threats North Korea made yesterday to attack “the White House, the Pentagon and the whole U.S. mainland” if the U.S. retaliates for the Sony hack. The spokeswoman said the State Department has “no specific credible threat information that lends credence” to the threat.
