According to Cointelegraph, the US Treasury Department announced on Friday that it would impose sanctions on three North Korean hacker organizations. Specifically, the sanctions targets Lazarus, a well-known hacker group, and two other lesser-known organizations, Bluenoroff and Andariel. In a UN report in early 2019, North Korean hacker group Lazarus was accused of making five cryptocurrency thefts, targeting Yapizon (Korea, loss of 3816 BTC, $5.3 million), Coinis (Korea, unknown), YouBit (Korea, losing 17% of assets), Coincheck (Japan, loss of 523 million NEM, $534 million), Bithumb (Korea, loss of $32 million), the total profit of five attacks was as high as $571 million. Last month, the UN Security Council’s “North Korea Sanctions Committee Panel” again reported that North Korea was suspected of conducting financial institutions and virtual currency exchanges in at least 17 countries between December 2015 and May 2019. Sub-network attacks have stolen nearly $2 billion in legal and cryptocurrencies. Subsequently, North Korea denied the accusation earlier this month and accused the United States of spreading rumors.
