According to Onchain Lens monitoring, Echo Protocol on Monad has been attacked. The attacker minted 1000 eBTC, worth $76.7 million, and withdrew the funds through Curvance via a previously tested attack path.
As of now, the attacker has deposited 45 eBTC as collateral into Curvance and borrowed approximately 11.29 WBTC, worth $867,700; the attacker then cross-chained this portion of WBTC to Ethereum, swapped it for ETH, and transferred 385 ETH (worth approximately $818,000) to Tornado Cash. The attacker currently appears to still control a large amount of the minted eBTC.
