This skill detects relay activity by querying Windows Security Event 4624 (successful logon) for type 3 network logons with NTLMSSP authentication, identifying mismatches between WorkstationName and source IpAddress, detecting rapid multi-host authentication from single accounts, and auditing SMB signing configuration across domain hosts.\n\n\n## When to Use\n\n- When investigating security incidents that require hunting for ntlm relay attacks\n- When building detection rules or threat hunting queries for this domain\n- When SOC analysts need structured procedures for this analysis type\n- When validating security monitoring coverage for related attack techniques\n\n## Prerequisites\n\n- Python 3.9+ with Windows Event Log access or exported logs\n- Windows Security audit logging enabled (Event ID 4624, 4625, 5145)\n- Network access for SMB signing status checks\n\n## Key Detection Areas\n\n1. **IP-hostname mismatch** — WorkstationName in Event 4624 does not resolve to the source IpAddress\n2. **NTLMSSP authentication** — logon events using NTLM instead of Kerberos from domain-joined hosts\n3. **Machine account relay** — computer accounts (ending in $) authenticating from unexpected IPs\n4. **Rapid authentication** — single account authenticating to multiple hosts within seconds\n5. **Named pipe access** — Event 5145 showing access to Spoolss, lsarpc, netlogon, samr pipes\n6. **SMB signing disabled** — hosts not enforcing SMB signing, enabling relay attacks\n\n## Output\n\nJSON report with suspected relay events, IP-hostname correlation anomalies, SMB signing audit results, and MITRE ATT&CK mapping to T1557.001.\n","# Hunting for NTLM Relay Attacks\n\n## Overview\n\nNTLM relay attacks intercept and forward NTLM authentication messages to gain unauthorized access to network resources.
