Liquidity pools on Ethereum lost between $237,000 and $240,000 in ETH after an attacker minted and dumped 1 billion DOT tokens. The attacker used a forged message to change the admin of the Polkadot token contract on Ethereum, gaining administrative rights to the Hyperbridge smart contract. This access allowed the attacker to bypass safeguards and mint 1 billion DOT tokens on the Ethereum network.
Once the tokens were generated, the attacker sold the entire amount into liquidity pools, extracting 108.2 ETH. The exploit targeted the ERC-20 version of the DOT coin operating on Ethereum, leaving the main Polkadot network unaffected.
Following the news of the exploit, the price of DOT fell between 4% and 6% to a range of $1.16 to $1.19.
