Flow Blockchain Implements Fix After Security Breach, Prepares for Full Network Restoration

Flow Blockchain's Swift Response to Security Breach

The Flow blockchain is on track for a comprehensive network restart following the implementation of a protocol fix after a recent security breach. The breach resulted in the loss of approximately $3.9 million due to a vulnerability in the execution layer, as reported by the Flow team.

Key Developments

• Flow blockchain validators have successfully deployed a protocol fix post-breach.
• Assets worth $3.9 million were moved off-network through a vulnerability in Flow's execution layer.

In response to the incident on December 27, where assets were transferred off-network using cross-chain bridges, Flow's network was temporarily paused to prevent further unauthorized activities. The Flow Foundation has confirmed the vulnerability has been isolated, and law enforcement is now involved. All user funds held prior to the breach remain unaffected.

Validators have reinstated the network to a pre-exploit checkpoint, enabling read-only mode as ecosystem partners align their systems. Transaction activity is suspended until full coordination is achieved. The network is anticipated to resume normal operations shortly, with a detailed technical post-mortem set for release within 72 hours.
