The Dolomite Exchange suffered an exploit of its old contracts on Ethereum, resulting in a loss of approximately $1.8 million in USDC. The attackers utilized a loophole in the TradeManager contract, bypassing reentrancy guards and exploiting the batchTransfer function of the TradeDelegate contract. This allowed them to transfer tokens approved to the contract from users, leading to a loss of ~$1.9m. In response, Dolomite confirmed that the hack did not impact their current product on the Arbitrum chain. Additionally, the AirDAO team reported a theft from their AMB/ETH Uniswap pool, losing 35.2 million AMB tokens and 125.51 ETH (totaling approximately $880K) due to a social engineering scam. Efforts are underway to identify the hacker and retrieve the stolen funds. Meanwhile, a wallet associated with BlackRock's new institutional crypto fund received 0.97 unsolicited ETH via Tornado Cash, potentially creating legal issues. This incident underscores the vulnerabilities and regulatory challenges within the cryptocurrency ecosystem.
