Pydun: Margin Agreement Arcadia遭受攻击，损失约45.5万美元

ChainCatcher news, according to PeckShield monitoring data, the on-chain collateral protocol Arcadia Finance has been attacked on the Ethereum and Optimism networks, resulting in a loss of approximately $455,000. The attacker has transferred 179.3 ETH to Tornado Cash mixer.

According to PeckShield's analysis, the attack was due to a lack of validation for untrusted inputs, which the attacker exploited to transfer funds from the darcWETH and darcUSDC vaults. Specifically, the attacker took advantage of a vulnerability in the ArcadiaFi project that allowed unverified input data to be accepted and executed malicious operations. (source link)
