Suspected North Korean hackers on Monday moved 12 bitcoin, worth about $140,000, from one of 280 accounts the U.S. Department of Justice (DoJ) has targeted for seizure.
“One of the inputs of this transaction has been listed by the U.S. government as forfeited. It is unclear who made the transaction,” Whale Alert tweeted, attaching a DoJ civil forfeiture complaint of August 27.

The 280 addresses are frozen because of the investigation, with exchanges cooperating so that the stolen funds are not converted to fiat and lost forever.
