Researchers say a North Korean hacker group stole $600 million of crypto in the Axie Infinity hack

North Korean hackers launched at least seven attacks in total on crypto platforms in 2021, exploiting almost $400 million worth of funds

The U.S. Treasury Department on Thursday added a new Ethereum address to its sanction list and linked it to North Korean hackers known as the Lazarus Group. Blockchain researchers said the address was likely behind the March hack of Ronin Bridge, a blockchain network connected to the popular play-to-earn game Axie Infinity, where more than $600 million worth of cryptocurrencies were stolen.
