With recent reports that North Korea may be again preparing for nuclear testing, today’s sanctions activity highlights the importance of ensuring that Lazarus Group is not able to successfully launder the proceeds of these attacks. Today the US Treasury’s Office of Foreign Assets Control (OFAC) sanctioned three Ethereum addresses which are being used to launder funds stolen from Ronin in March by North Korea’s Lazarus group. Many commentators believe that cryptocurrency stolen by Lazarus Group is used to fund the State’s nuclear and ballistic missile programmes. Initially, Lazarus attempted to launder the stolen ETH through centralised exchanges including Binance, which announced today that it had recovered $5.8 million.
