Windows Server Failover Cluster (WSFC) implementations represent a critical yet underexamined attack surface in enterprise environments. This research exposes how WSFC's architectural design inadvertently creates exploitable abuse paths and presents novel attack methodologies demonstrating how the compromise of a single cluster node can lead to complete cluster takeover, lateral movement across clustered infrastructure, and ultimately, domain compromise.
This Briefing will present previously undiscovered techniques for extracting and leveraging cluster credentials, manipulating Kerberos authentication, and exploiting excessive permissions granted to cluster objects. This "set it and forget it" high-availability infrastructure represents a significant blind spot for organizations.
You will leave with a better understanding of WSFC's internal security architecture, strategies for enumerating and abusing these new attack paths, and concrete defensive guidance for protecting organizations from these new abuses.
