**June 23, 2022 — Harmony Horizon bridge exploit (~$97M):** an attacker apparently controlled a MultiSigWallet owner to submit/confirm and execute bridge transactions, unlocking 13,100 ETH and numerous ERC‑20 tokens (USDC, WBTC, USDT, DAI, BUSD, etc.), resulting in an estimated $97M loss on the Harmony chain; stolen assets were consolidated into a single exploiter address and remain held.
