US moves to seize cryptocurrency accounts linked to North Korean heists

US authorities on Thursday moved to seize 280 cryptocurrency accounts they said were used by North Korean hackers who stole more than a quarter of a billion dollars from cryptocurrency companies around the world, including one in the U.S.

The U.S. Justice Department said the accounts targeted in the civil forfeiture filing were used by the North Korean hackers and their Chinese agents to launder some of the money stolen from more than a dozen virtual currency exchanges, a series of cyber thefts over the past two years amounting to more than $300 million.
