According to Arkham monitoring, a wallet controlled by the US government is suspected to have been hacked. The wallet contains funds seized from the Bitfinex hack in 2016, which has caused the address to lose $20 million.
The attacker sent the funds to a wallet starting with "0x348", which included USDC, USDT, aUSDC and ETH. Hackers have begun converting stablecoins to ETH and laundering money through addresses that may be related to money laundering services.
Earlier news, the US government address (Bitfinex hacker seized funds) withdrew $6.57 million worth of stablecoins from Aave early this morning. The funds were transferred to the address starting with "0x348", and then the address exchanged about 5.45 million USDC for 2135.27 ETH.
