Escaping the Confines of Port 445

This post outlines a technique to break out of SMB/445-only constraints during NTLM relay by using the Service Control Manager to remotely start the WebClient service via a relayed admin session, enabling WebDAV-based coercion that can be relayed to LDAP on domain controllers lacking LDAP signing/channel binding, and facilitating computer account takeover through RBCD or Shadow Credentials. It demonstrates using ntlmrelayx’s SOCKS to proxy native Windows service tools (services.msc/sc.exe) for lower detection risk, thereby expanding lateral movement options beyond SMB while avoiding common EDR alerts.
