North Korean hackers associated with the Lazarus Group have laundered $12 million worth of Ethereum (ETH) using the coin mixing service Tornado Cash in the past 24 hours. Research by blockchain analysis company Elliptic shows that Lazarus Group sent over 40 transactions to Tornado Cash on March 13th and 14th. Elliptic also attributed the $100 million Heco Bridge and HTX hack in November last year to the Lazarus Group.
