Flow network experienced a protocol layer vulnerability attack on December 27th. The attacker exploited this vulnerability to bypass the authorization mechanism, minting a large amount of FLOW tokens and circulating them in the market, causing serious disruptions to network stability and market order.

A leading exchange immediately activated its emergency response mechanism, coordinating with the project team to carry out multi-level mitigation efforts. On-chain, real-time monitoring was used to track the flow of funds related to the attacker; in terms of risk control, comprehensive restrictions were imposed on identifiable hacker-related asset accounts to prevent further outflows. This incident once again reminds market participants to pay attention to underlying protocol risks, while also demonstrating the rapid response capability of trading platforms in handling sudden security events.
