Echo Protocol on Monad Exploited for $76M — Hacker Still Holds $73M in Stolen eBTC!

Echo Protocol, a DeFi project on Monad, has been exploited in a sophisticated multi-step attack that minted 1,000 eBTC tokens worth approximately $76.64 million. The attacker then used Curvance as a stepping stone, depositing 45 eBTC ($3.45M) as collateral to borrow 11.3 WBTC ($867K) against it.

The stolen WBTC was bridged to Ethereum and swapped for 385 ETH ($821K), which was then routed through Tornado Cash to obscure the trail. The laundered portion represents only a fraction of the total theft — the hacker still controls 955 eBTC worth roughly $73.2 million, meaning the bulk of the exploit proceeds remain on-chain and unmoved.

The attack follows a now-familiar playbook: mint or borrow inflated collateral, extract liquid assets through a lending protocol, bridge to Ethereum, and launder through Tornado Cash. The $73.2M sitting in the attacker's wallet puts pressure on the Monad and…
