Flow: The published protocol fix is in place, and node operators are coordinating deployment to roll back to the pre-attack state.

Techub News: Flow Releases Update, Announces Protocol Fixes and Network Rollback

Flow has announced that it has released a protocol fix and that node operators are coordinating the deployment of this upgrade to address the vulnerability exploited yesterday. The network will be restored to a checkpoint prior to the attack, removing all unauthorized transactions from the ledger. Flow states that this rollback is a necessary measure to clear the impact of the attack. Users are reminded that transactions submitted between approximately 15:25 and 21:30 on December 27 during the network outage will need to be resubmitted after the network restarts, including all legitimate user activities during that period. The Foundation will confirm once the network is officially back online.

Flow reports that on December 27, attackers exploited a vulnerability in the Flow execution layer to transfer approximately $3.9 million worth of assets before the network shutdown. The attack did not access existing user balances, and all user deposits are safe. Currently, about $3.9 million has been moved out via 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 freeze requests to Circle, Tether, and major trading platforms.
