The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) announced new sanctions for the Lazarus Group’s Ethereum wallet, announced on Thursday.
According to crypto experts, the wallet in question contains digital assets related to the recent attack on Ronin Network, which is connected to the popular blockchain game Axie Infinity. Ether and USDC worth over $600 million are believed to have been stolen in the attack.

It turned out that they took advantage of a vulnerability in the tool called Bridges stand out as an increasingly popular tool in the rapidly growing world of “decentralized finance” (DeFi).
Blockchain analytics firm Elliptic noted in a blog post that the newly announced sanctions are aimed at preventing hackers from cashing in their holdings on American crypto Exchanges by prohibiting US individuals and institutions from transacting with the designated Ethereum account.
Another crypto research group called Chainanalysis pointed out that the sanctions imposed on Lazarus underline “how groups associated with North Korea can abuse crypto systems and the need for better security protocols in DeFi systems.”
