Abstract This research presents a comprehensive analysis of IPv6 DNS takeover vulnerabilities in Windows 11 enter- prise networks, demonstrating a critical security gap in default network configurations. Through systematic experimentation in controlled laboratory environments, we identified and exploited a fundamental weakness in how Windows systems handle DHCPv6 solicitations and DNS resolution, particularly when combined with the Web Proxy Auto-Discovery (WPAD) protocol. Our study reveals that 95% of Windows systems with default configurations are vulnerable to credential harvesting attacks through IPv6 DNS manipulation, with successful NTLMv2 hash capture occurring within 2-3 minutes of attack initiation. We developed dual- purpose automated tools: an offensive penetration testing utility achieving 90% evasion rate against standard security tools, and a comprehensive PowerShell-based defense mechanism providing real-time attack detection and automated hardening. The re- search demonstrates that despite Windows 11’s enhanced security features, the default enablement of IPv6 combined with automatic WPAD discovery creates an exploitable attack surface requiring immediate attention. Our findings indicate that organizations can achieve complete mitigation through strategic IPv6 configuration management, WPAD disablement, and implementation of our proposed monitoring framework. This work contributes both practical security tools and actionable recommendations for securing modern Windows networks against emerging IPv6- based threats.
