In line with blockchain monitoring agency Chainalysis, the tackle that the OFAC linked was the identical tackle that obtained 173,000 ETH after the Ronin hack.
“The attribution of the Ronin hack to Lazarus Group underlines two trade wants Chainalysis has highlighted beforehand: Understanding of how DPRK-affiliated risk actors exploit crypto, and higher safety for DeFi protocols,” Chainalysis mentioned, including “The newly designated ETH tackle has now been labelled within the Sanctions class in all Chainalysis merchandise.”
Ronin mentioned the hack, which occurred final month, occurred when an attacker managed to take management over the non-public keys for its validator nodes and the nodes for the Axie Infinity Decentralized Autonomous Group (DAO).

Sky Mavis was solely supposed to have the ability to signal transactions on the DAO’s behalf quickly, however allowlist entry was not correctly revoked. This meant the attacker was ready to make use of Sky Mavis as a backdoor to entry The Ronin bridge and Katana Dex.
In its newest report, Chainalysis says that hackers are stealing extra from decentralized finance (DeFi) platforms than ever earlier than.
“Up to now, cryptocurrency hacks had been largely the results of safety breaches by which hackers gained entry to victims’ non-public keys—the crypto-equivalent of pickpocketing. Ronin Community’s March 2022 breach, which enabled the theft of $615 million in cryptocurrency, has confirmed the continued effectiveness of this system.”
Earlier than the Ronin assault, the most important DeFi hack on document was final yr when a foul actor exploited the Poly Community for $613 million. Within the case of Poly Community although, the funds had been ultimately returned for a “small” white-hat reward of $500,000.
