The company explicitly states its new Arc network may be vulnerable to sophisticated attacks like double-spending, validator collusion, and Sybil attacks. This highlights a critical need for advanced security monitoring, threat detection, and incident response solutions to protect the network's integrity and user assets.
Filing excerpt
In addition to consensus-layer attacks, Arc may be vulnerable to Sybil attacks, eclipse attacks, routing attacks and other forms of sophisticated adversarial behavior. We cannot guarantee that Arc's security model will be sufficient to prevent all such attacks, and any successful attack could result in significant harm to Arc users, the value of the ARC Token and our reputation.
