Echo Protocol on Monad was attacked, and the attacker minted 1,000 eBTC worth $76.7 million before routing funds through Curvance. Onchain Lens said the attacker later deposited 45 eBTC as collateral into Curvance and borrowed about 11.29 WBTC worth $867,700. The attacker bridged that WBTC to Ethereum, swapped it for ETH, and sent 385 ETH worth about $818,000 to Tornado Cash. The attacker still appears to control a large amount of the minted eBTC.
