Wormhole Solana-Ethereum bridge exploited for ~$325M

On February 2, 2022, an attacker exploited a signature-verification flaw in the Wormhole bridge to mint 120,000 wETH on Solana without posting any collateral, draining roughly $325 million. Backer Jump Trading quietly replaced the funds within a day, a reminder of how much capital was riding on bridge code that nobody had audited quite hard enough.
