Polkadot token exploit sees 1B tokens minted in Hyperbridge attack

An attacker exploited the Hyperbridge gateway contract to mint 1 billion Polkadot tokens on Ethereum, selling them for $237,000. By reusing a transaction proof, the attacker gained admin control. Polkadot stated only bridged DOT via Hyperbridge is impacted, while the native network and parachains remain unaffected. Hyperbridge is currently paused for investigation.
