The Flow Foundation has confirmed a security incident on December 27, 2025. An attacker moved approximately $3.9M off-network before validators halted the network. No user balances were affected and all deposits remain safe.
The incident is fully contained. A protocol fix is in final validation, with a target restart within 4–6 hours, pending testing. We are closely monitoring the situation and will share more updates as new information becomes available.
