[Flow Hacked, $3.9 Million Lost, User Deposits Unaffected] The Flow Foundation announced that on December 27, attackers exploited a vulnerability in the Flow execution layer to transfer approximately $3.9 million worth of assets out of the network before validators could coordinate to halt operations. This incident did not impact existing user balances, and all user deposits remain unaffected. A protocol fix has been developed and released, and node operators are coordinating to deploy the upgrade. The network will roll back to a checkpoint prior to the exploit to remove unauthorized transactions.
