Golden Finance reported that Ronin released an update saying that after being notified by a white hat hacker, a potential vulnerability in the Ronin bridge was discovered. After verification, the team suspended the operation of the bridge about 40 minutes after the first on-chain action. The attacker withdrew about 4,000 ETH and 2 million USDC, worth about $12 million. This withdrawal amount is exactly the maximum amount that can be withdrawn in a single transaction, showing that the withdrawal limit of the bridge played a key role in this incident and effectively prevented larger-scale losses. The Ronin team said that today's bridge upgrade introduced a problem in the governance process, causing the system to misunderstand the bridge operator voting threshold required to withdraw funds. The team is working to address this root cause and plans to re-vote after a rigorous audit to ensure the security of the bridge. Currently, Ronin is in negotiations with the attacker, who appears to be acting as a white hat hacker and showing goodwill. Regardless of the outcome of the negotiations, all users' funds are safe, and any shortage will be replenished when the bridge reopens. The team also said that a post-mortem analysis will be released next week, detailing the technical details of the incident and future preventive measures.
