Rule: title: ISATAP Router Address Was Set id: d22df9cd-2aee-4089-93c7-9dc4eae77f2c status: experimental description: 'Detects the configuration of a new ISATAP router on a Windows host. While ISATAP is a legitimate Microsoft technology for IPv6 transition, unexpected or unauthorized ISATAP router configurations could indicate a potential IPv6 DNS Takeover attack using tools like mitm6. In such attacks, adversaries advertise themselves as DHCPv6 servers and set malicious ISATAP routers to intercept traffic. This detection should be correlated with network baselines and known legitimate ISATAP deployments in your environment.
