Detection focuses on identifying WmiPrvSE.exe spawning child processes (cmd.exe, powershell.exe) in Windows Security Event ID 4688 and Sysmon Event ID 1 logs, along with WMI-Activity/Operational events (5857, 5860, 5861) for event subscription persistence.\n\n\n## When to Use\n\n- When investigating security incidents that require hunting for lateral movement via wmi\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- Windows Security Event Logs with Process Creation auditing enabled (Event 4688 with command line)\n- Sysmon installed with Event ID 1 (Process Creation) configured\n- Python 3.9+ with `python-evtx`, `lxml` libraries\n- Understanding of WMI architecture and WmiPrvSE.exe behavior\n\n## Steps\n\n### Step 1: Parse Process Creation Events\nExtract Event ID 4688 and Sysmon Event 1 entries from EVTX files.\n\n### Step 2: Detect WmiPrvSE Child Processes\nFlag processes where ParentImage/ParentProcessName is WmiPrvSE.exe, indicating remote WMI execution.\n\n### Step 3: Analyze Command Line Patterns\nIdentify suspicious command lines matching WMI lateral movement patterns (cmd.exe /q /c, output redirection to admin$ share).\n\n### Step 4: Check WMI Event Subscriptions\nParse WMI-Activity/Operational log for event consumer creation indicating persistence.\n\n## Expected Output\n\nJSON report with WMI-spawned processes, suspicious command lines, WMI event subscription alerts, and timeline of lateral movement activity.\n\n## Other files in this skill\n\n-

Indicator | MITRE |\n|---------|-----------|-------|\n| WmiPrvSE -> cmd.exe | Remote command execution | T1047 |\n| WmiPrvSE -> powershell.exe | Remote PowerShell via WMI | T1047 |\n| cmd.exe /q /c ... admin$ | WMI output redirection | T1047 |\n| Event 5861 consumer | WMI event subscription persistence | T1546.003 |\n| wmic process call create | Direct WMI process creation | T1047 |\n\n## Suspicious Child Processes of WmiPrvSE.exe\n\n| Process | Risk Level | Context |\n|---------|------------|---------|\n| cmd.exe | High | Command execution |\n| powershell.exe | High | Script execution |\n| mshta.exe | Critical | HTA script execution |\n| cscript.exe | High | VBScript/JScript |\n| regsvr32.exe | High | COM object registration |\n| rundll32.exe | High | DLL execution |\n\n## Command Line Regex Patterns\n\n```python\n# WMI remote execution via cmd\nr\"cmd\\.exe\\s+/[qQ]\\s+/[cC]\"\n\n# Output to admin$ share\nr\"\\\\\\\\127\\.0\\.0\\.1\\\\admin\\$\\\\__\\d+\"\n\n# WMIC process
