Orbit Bridge reported an exploit of its Ethereum vault in which an unidentified attacker conducted six theft transactions affecting ETH, WBTC, USDT, USDC, and DAI with losses estimated at about $81.5 million. Orbit Chain said it worked with the Korean National Police Agency, KISA, Theori, and other authorities, halted the Ethereum vault to prevent further damage, and observed stolen assets swapped into ETH and DAI before being split across eight wallets.
