How Arbitrum Froze a Hacker’s Crypto in 10 Minutes

Arbitrum’s Security Council moved 8,425 ETH and 74.6 million ARB linked to the October 29 Binance hack into an address ending 0DA0 on October 30 at 8:08 a.m. Hong Kong time. The council used a temporary Inbox function, sendUnsignedTransactionOverride, to make Arbitrum One accept transactions naming the exploit address as sender without its private key. The council said no other users’ funds or applications were affected. The assets can leave the holding address only through a separate ArbitrumDAO governance vote.
