- HongCoin, the 2016 ICO that failed so hard it became a fossil, just woke up. Whitehat 0xFlorent didn’t hack it; he used a pre-Solidity 0.8 integer overflow bug to reset accounting counters, allowing 48 investors to claim their trapped 1,003 ETH (approx $2M). It’s not a heist; it’s contract archaeology. The original multisig actually cooperated, proving that old Ethereum code is both a liability and a time capsule. While regulators sleep, legacy bugs are paying dividends. Check your old wallets before they turn into digital museum pieces.
