Arbitrum security council moves $30 million in Binance hack funds without private key
Arbitrum's 12-member security council used emergency network powers to transfer roughly $30 million in stolen crypto assets without the attacker's authorization, temporarily rewriting core contract code to recover the tokens.

Arbitrum's 12-member security council has intervened to move approximately $30 million in funds tied to a Binance exploit without using the attacker's private key. The recovered assets, comprising over 8,425 ETH and 74 million ARB tokens, were transferred using emergency upgrade authority that required approval from nine council members.[1][2][3]
To execute the transfer, the committee briefly modified one of Arbitrum's core smart contracts to authorize spending from the target address before immediately restoring the original code, according to CoinDesk. The outlet noted that this marks the second time this year the council has taken such an action.[2]
The assets, which Analytics Insight reported are linked to a wider $6.3 billion Binance hack, are now secured in a dedicated holding wallet. The next steps for the recovered funds are currently pending an ArbitrumDAO governance vote.[1][3]
