THORChain Swap Halt Accidentally Slows North Korean Hackers Laundering Binance’s $6.3B Hack

TLDR THORChain paused swaps on 10 networks, including Bitcoin, Ethereum, Solana and Tron, after an Ethereum reorg exposed a refund bug. A 10 ETH deposit was removed by the reorg, and THORChain still refunded it, causing an extra 10 ETH payout. Chainalysis said the pause unintentionally delayed North Korean hackers from laundering funds stolen in the $6.3 billion Binance hack. The FBI asked THORChain node operators and DeFi services to block addresses tied to the hacking group TraderTraitor. Swaps still work on Avalanche, Base and XRP, and nodes will re-enable the other chains once they are judged safe.
