OFAC sanctioned this address as attributed to a state sponsored hack by North Korea targeting Ronin.

The Ronin bridge suffered a hack. According to Ronan network, " Sky Mavis’s Ronin validator nodes and Axie DAO validator nodes were compromised resulting in 173,600 Ethereum and 25.5M USDC drained from the Ronin bridge in two transactions (1 and 2). The attacker used hacked private keys in order to forge fake withdrawals. We discovered the attack this morning after a report from a user being unable to withdraw 5k ETH from the bridge. "
