Flow: A protocol fix has been released, and node operators are coordinating deployment to roll back to the pre-attack state.

According to Foresight News , Flow has released an update stating that its blockchain has published a protocol fix, and node operators are coordinating the deployment of this upgrade to address the exploit issue that occurred yesterday. The network will be restored to a checkpoint before the attack to remove all unauthorized transactions from the ledger. Flow stated that this rollback is a necessary measure to mitigate the impact of the attack. Users are reminded that transactions submitted during the network outage from approximately 15:25 to 21:30 on December 27th need to be resubmitted after the network restart, including all legitimate user activity during that period. The foundation will confirm this when the network officially launches.

Flow stated that on December 27th, attackers exploited a vulnerability in the Flow execution layer to transfer approximately $3.9 million in assets before a network outage. The attack did not access users' existing balances, and all user deposits are safe. Currently, the approximately $3.9 million flowed primarily through bridges such as Celer, Debridge, Relay, and Stargate. The attacker's wallet has been identified and flagged, and their money laundering activities through Thorchain and Chainflip are being tracked in real-time. The Flow Foundation has also submitted requests to Circle, Tether, and major trading platforms to freeze the funds.
