Performing Lateral Movement Detection\n\n## When to Use\n\nUse this skill when:\n- SOC teams need to detect attackers pivoting between systems after initial compromise\n- Incident investigations require tracking an attacker's movement path through the network\n- Detection engineering needs lateral movement rules mapped to ATT&CK TA0008 techniques\n- Red/purple team exercises identify lateral movement detection gaps\n\n**Do not use** for detecting initial access or external attacks — lateral movement detection focuses on internal host-to-host pivot activity.\n\n## Prerequisites\n\n- Windows Security Event Logs (EventCode 4624, 4625, 4648, 4672) from all endpoints and servers\n- Sysmon deployed with process creation (EventCode 1), network connections (EventCode 3), and named pipe (EventCode 17/18)\n- Network flow data (NetFlow/sFlow, Zeek connection logs) for internal traffic analysis\n- SIEM with cross-source correlation capability\n- Baseline of normal internal authentication patterns\n\n## Workflow\n\n### Step 1: Detect Pass-the-Hash / Pass-the-Ticket (T1550)\n\n**Pass-the-Hash Detection (EventCode 4624 with NTLM):**\n```spl\nindex=wineventlog sourcetype=\"WinEventLog:Security\" EventCode=4624 Logon_Type=3\nAuthenticationPackageName=\"NTLM\"\n| where TargetUserName!=\"ANONYMOUS LOGON\" AND TargetUserName!=\"$\"\n| stats count, dc(ComputerName) AS unique_targets, values(ComputerName) AS targets\n  by src_ip, TargetUserName\n| where unique_targets > 3\n| eval alert = \"Possible Pass-the-Hash: NTLM network logon to \".unique_targets.\" hosts\"\n| sort - unique_targets\n| table src_ip, TargetUserName, unique_targets, count, targets, alert\n```\n\n**Overpass-the-Hash Detection (Kerberos with RC4):**\n```spl\nindex=wineventlog sourcetype=\"WinEventLog:Security\" EventCode=4769\nTicketEncryptionType=\"0x17\"\n| where ServiceName!=\"krbtgt\" AND ServiceName!=\"$\"\n| stats count, dc(ServiceName) AS unique_services by src_ip, TargetUserName\n| where count > 5\n| eval alert = \"Possible Overpass-the-Hash: RC4 Kerberos tickets from \".src_ip\n| table _time, src_ip, TargetUserName, unique_services, count, alert\n```\n\n**Golden/Silver Ticket Detection (T1558):**\n```spl\nindex=wineventlog sourcetype=\"WinEventLog:Security\" EventCode=4769\n| where TicketOptions=\"0x40810000\" OR TicketOptions=\"0x40800000\"\n| eval ticket_lifetime = TicketExpireTime - TicketIssueTime\n| where ticket_lifetime > 36000  --- >10 hours (abnormal)\n| stats count by src_ip, TargetUserName, ServiceName, TicketEncryptionType, TicketOptions\n| eval alert = \"Possible Golden/Silver Ticket: Abnormal ticket properties\"\n```\n\n### Step 2: Detect Remote Service Exploitation (T1021)\n\n**PsExec Detection (T1021.002):**\n```spl\n--- Via Sysmon process creation\nindex=sysmon EventCode=1\n(Image=\"*\\\\psexec.exe\" OR Image=\"*\\\\psexesvc.exe\"\n OR OriginalFileName=\"psexec.c\" OR OriginalFileName=\"psexesvc.exe\"\n OR ParentImage=\"*\\\\psexesvc.exe\")\n| table _time, Computer, User, ParentImage, Image, CommandLine, Hashes\n\n--- Via named pipe creation (Sysmon EventCode 17)\nindex=sysmon EventCode=17\nPipeName IN (\"\\\\PSEXESVC*\", \"\\\\RemCom*\", \"\\\\csexec*\")\n| table _time, Computer, User, Image, PipeName\n\n--- Via Windows service creation (EventCode 7045)\nindex=wineventlog sourcetype=\"WinEventLog:System\" EventCode=7045\nServiceName=\"PSEXESVC\" OR ServiceFileName=\"*PSEXESVC*\"\n| table _time, Computer, ServiceName, ServiceFileName, AccountName\n```\n\n**WMI Remote Execution (T1047):**\n```spl\nindex=sysmon EventCode=1\n(Image=\"*\\\\wmic.exe\" AND CommandLine=\"*/node:*\")\nOR (ParentImage=\"*\\\\WmiPrvSE.exe\" AND Image IN (\"*\\\\cmd.exe\", \"*\\\\powershell.exe\"))\n| eval execution_type = case(\n    match(Image, \"wmic\"), \"WMI Command Line\",\n    match(ParentImage, \"WmiPrvSE\"), \"WMI Provider Host (remote execution)\"\n  )\n| table _time, Computer, User, execution_type, ParentImage, Image, CommandLine\n```\n\n**WinRM/PowerShell Remoting (T1021.006):**\n```spl\nindex=wineventlog sourcetype=\"WinEventLog:Security\" EventCode=4624\nLogon_Type=3 AuthenticationPackageName=\"Kerberos\"\n| where ProcessName=\"*\\\\wsmprovhost.exe\" OR ProcessName=\"*\\\\powershell.exe\"\n| stats count, dc(ComputerName) AS unique_targets by src_ip, TargetUserName\n| where unique_targets > 2\n| eval alert = \"PowerShell Remoting to \".unique_targets.\" hosts from \".src_ip\n\n--- Sysmon variant\nindex=sysmon EventCode=1\nParentImage=\"*\\\\wsmprovhost.exe\"\nImage IN (\"*\\\\cmd.exe\", \"*\\\\powershell.exe\", \"*\\\\csc.exe\")\n| table _time, Computer, User, Image, CommandLine\n```\n\n**RDP Lateral Movement (T1021.001):**\n```spl\nindex=wineventlog sourcetype=\"WinEventLog:Security\" EventCode=4624 Logon_Type=10\n| stats count, dc(ComputerName) AS rdp_targets, values(ComputerName) AS destinations,\n        earliest(_time) AS first_rdp, latest(_time) AS last_rdp\n  by src_ip, TargetUserName\n| where rdp_targets > 2\n| eval duration_hours = round((last_rdp - first_rdp) / 3600, 1)\n| eval alert = TargetUserName.\" RDP'd to \".rdp_targets.\" hosts in \".duration_hours.\" hours\"\n| sort - rdp_targets\n```\n\n### Step 3: Detect SMB-Based Lateral Movement\n\n**Anomalous SMB Traffic Patterns:**\n```spl\nindex=firewall OR index=zeek sourcetype IN (\"pan:traffic\", \"bro:conn:json\")\ndest_port=445 action=allowed\n| where src_ip!=dest_ip\n| stats count AS smb_sessions, dc(dest_ip) AS unique_targets,\n        sum(bytes_out) AS total_bytes\n  by src_ip\n| where unique_targets > 10\n| eval alert = case(\n    unique_targets > 50, \"CRITICAL: Mass SMB enumeration from \".src_ip,\n    unique_targets > 20, \"HIGH: Significant SMB lateral movement\",\n    unique_targets > 10, \"MEDIUM: Elevated SMB connections\"\n  )\n| sort - unique_targets\n```\n\n**Admin Share Access (C$, ADMIN$):**\n```spl\nindex=wineventlog sourcetype=\"WinEventLog:Security\" EventCode=5140\nShareName IN (\"\\\\\\\\*\\\\C$\", \"\\\\\\\\*\\\\ADMIN$\", \"\\\\\\\\*\\\\IPC$\")\n| where SubjectUserName!=\"SYSTEM\" AND SubjectUserName!=\"$\"\n| stats count, dc(ComputerName) AS unique_hosts by SubjectUserName, ShareName, src_ip\n| where unique_hosts > 3\n| eval alert = \"Admin share access to \".unique_hosts.\" hosts by \".SubjectUserName\n| sort - unique_hosts\n```\n\n### Step 4: Build Lateral Movement Graph\n\nVisualize the attack path:\n\n```spl\n--- Build source->destination graph for authentication events\nindex=wineventlog EventCode=4624 Logon_Type IN (3, 10)\nearliest=-24h\n| stats count AS connections, latest(_time) AS last_connection\n  by src_ip, ComputerName, TargetUserName, Logon_Type\n| eval edge = src_ip.\" -> \".ComputerName.\" (User: \".TargetUserName.\", Type: \".Logon_Type.\")\"\n| sort - connections\n| table edge, connections, last_connection\n\n--- Network flow correlation\nindex=netflow earliest=-24h\ndest_port IN (445, 135, 3389, 5985, 5986)\n| stats sum(bytes) AS total_bytes, count AS flow_count,\n        dc(dest_ip) AS targets by src_ip, dest_port\n| where targets > 5\n| eval service = case(\n    dest_port=445, \"SMB\",\n    dest_port=135, \"RPC/WMI\",\n    dest_port=3389, \"RDP\",\n    dest_port IN (5985, 5986), \"WinRM\"\n  )\n| sort - targets\n| table src_ip, service, targets, flow_count, total_bytes\n```\n\n### Step 5: Detect DCOM and Scheduled Task-Based Movement\n\n**DCOM Lateral Execution (T1021.003):**\n```spl\nindex=sysmon EventCode=1\nParentImage IN (\"*\\\\mmc.exe\", \"*\\\\excel.exe\", \"*\\\\outlook.exe\")\nImage IN (\"*\\\\cmd.exe\", \"*\\\\powershell.exe\", \"*\\\\mshta.exe\")\n| where ParentCommandLine=\"*-Embedding*\"\n| eval alert = \"DCOM-based lateral movement: \".ParentImage.\" spawned \".Image\n| table _time, Computer, User, ParentImage, Image, CommandLine, alert\n```\n\n**Remote Scheduled Task Creation (T1053.005):**\n```spl\nindex=wineventlog EventCode=4698\n| where SubjectUserName!=\"SYSTEM\"\n| eval task_xml = TaskContent\n| search task_xml=\"*http*\" OR task_xml=\"*powershell*\" OR task_xml=\"*cmd*\" OR task_xml=\"*\\\\Temp\\\\*\"\n| table _time, Computer, SubjectUserName, TaskName, task_xml\n```\n\n### Step 6: Correlate Movement with Kill Chain Phases\n\nBuild end-to-end attack chain detection:\n\n```spl\n--- Detect complete lateral movement sequence\nindex=wineventlog OR index=sysmon\n(EventCode=4625 OR EventCode=4624 OR EventCode=1 OR EventCode=4698 OR EventCode=5140)\n| eval phase = case(\n    EventCode=4625, \"1-Recon/BruteForce\",\n    EventCode=4624 AND Logon_Type=3, \"2-Lateral Movement\",\n    EventCode=5140 AND match(ShareName, \"C\\$|ADMIN\\$\"), \"3-Admin Share Access\",\n    EventCode=1 AND match(ParentImage, \"psexesvc|WmiPrvSE|wsmprovhost\"), \"4-Remote Execution\",\n    EventCode=4698, \"5-Persistence (Scheduled Task)\",\n    1=1, \"other\"\n  )\n| where phase!=\"other\"\n| stats count by phase, src_ip, ComputerName, TargetUserName\n| sort phase, _time\n| table phase, src_ip, ComputerName, TargetUserName, count\n```\n\n## Key Concepts\n\n| Term | Definition |\n|------|-----------|\n| **Lateral Movement** | Post-compromise technique where attackers pivot between systems to reach targets |\n| **Pass-the-Hash** | Using stolen NTLM hash for authentication without knowing the plaintext password |\n| **Pass-the-Ticket** | Using stolen Kerberos TGT/TGS tickets for authentication across the domain |\n| **PsExec** | Sysinternals tool (and attack technique) for remote process execution via SMB and named pipes |\n| **WMI Execution** | Using Windows Management Instrumentation for remote command execution via DCOM or WinRM |\n| **Admin Share** | Default Windows administrative shares (C$, ADMIN$, IPC$) used for remote system management |\n\n## Tools & Systems\n\n- **Splunk Enterprise Security**: SIEM platform for correlating Windows events, Sysmon, and network flows\n- **Microsoft Defender for Identity**: Cloud service detecting lateral movement via domain controller monitoring\n- **BloodHound**: Active Directory attack path analysis tool for identifying lateral movement opportunities\n- **CrowdStrike Falcon**: EDR platform with lateral movement detection and automated containment\n- **Zeek (Bro)**: Network monitor generating connection logs for SMB, RDP, and WinRM traffic analysis\n\n## Common Scenarios\n\n- **PsExec Spread**: Attacker uses PsExec to execute malware across 20 workstations — detect via service creation events\n- **RDP Pivoting**: Compromised VPN account used to RDP through multiple internal hosts — detect via Logon_Type 10 chains\n- **WMI Recon and Execution**: Attacker uses WMI for discovery then execution — detect via WmiPrvSE child processes\n- **Pass-the-Hash Campaign**: Stolen local admin hash used across subnet — detect via NTLM Logon_Type 3 to multiple hosts\n- **Scheduled Task Persistence**: Remote scheduled task created on domain controller — detect via EventCode 4698 from non-admin source\n\n## Output Format\n\n```\nLATERAL MOVEMENT DETECTION REPORT\n━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━\nPeriod:       2024-03-15 14:00 to 18:00 UTC\nSource:       192.168.1.105
