A wallet linked to North Korea's notorious Lazarus Group has reportedly sold 40.78 Wrapped Bitcoin (WBTC) for$3.51 million, exchanging it for 1,847 Ethereum (ETH), according to data from SpotOnChain.

Instead of holding onto the ETH, the wallet redistributed 2,507 ETH across three separate addresses, with the largest portion of 1,865 ETH sent to another wallet allegedly tied to the hacker group.

The wallet originally purchased the 40.78 WBTC in February 2023 for around$999,900, when the price of WBTC averaged$24,521. Instead of selling earlier, the group waited until WBTC surged to$83,459, securing a realised profit of$2.51 million, representing a 251% gain over two years.

Lazarus Group, instead of operating openly, has been using complex laundering techniques to move stolen funds, particularly after its attack on crypto exchange Bybit.

In March, the group allegedly laundered nearly 500,000 ETH-worth$1.39 billion-through various transactions in just ten days, instead of keeping the stolen assets in a single location. At least$605 million was processed via the THORChain platform in a single day.

According to Arkham Intelligence, a wallet linked to the group still holds approximately$1.1 billion in crypto, with substantial reserves in Bitcoin, Ethereum, and Tether.

Meanwhile, Google's Threat Intelligence Group has reported increased efforts by North Korean IT workers to infiltrate European tech and crypto firms, acting as insider operatives for state-sponsored cybercrime networks like Lazarus Group instead of working as legitimate employees.
