IPv6 Hijack Attack Demo Shows How to Exploit and Defend Dual-Stack Networks
A developer built a dual-stack enterprise network in GNS3 and demonstrated a silent IPv6 man-in-the-middle attack using a Python script that exploits SLAAC. The attack was fully mitigated with RA Guard and parallel ACL policies. The project highlights how IPv6 security is often overlooked in enterprise environments.
