Hacker Steals $237K after Minting 1B Bridged DOT on Hyperbridge
Cointelegraph
An attacker exploited Hyperbridge to mint 1 billion fake DOT tokens, netting approximately $237,000 before the protocol paused operations.Summary
A hacker successfully exploited the Polkadot-based cross-chain protocol Hyperbridge by forging a message to change the admin of the Polkadot token contract on Ethereum. The attacker minted 1 billion bridged DOT tokens, though limited liquidity allowed them to siphon only about 108.2 ETH, valued at $237,000. Hyperbridge has paused operations to investigate a suspected vulnerability in its Merkle tree verifier, while native DOT tokens remain unaffected.
