Echo Protocol on Monad Hit by Exploit; Attacker Mints 1,000 eBTC and Routes ETH to Tornado Cash

May 19 — BlockBeats reports that PeckShield monitoring flagged an exploit involving Echo Protocol on Monad. The attacker minted 1,000 eBTC, valued at about $76.7 million. Using a method reportedly tested beforehand, the attacker deposited 45 eBTC (around $3.45 million) into Curvance, then borrowed roughly 11.29 WBTC (about $867,700) against the collateral. The WBTC was bridged to Ethereum, swapped into ETH, and 384 ETH (approximately $821,700) was ultimately sent to Tornado Cash.
