Echo Protocol attacked, attacker mints 1000 eBTC and then withdraws funds via Curvance

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.
