API Reference: Hunting for Lateral Movement via WMI

Detection Event IDs

Source	Event ID	Description
Security	4688	Process creation (enable command line auditing)
Sysmon	1	Process creation with full details
WMI-Activity	5857	WMI provider loaded
WMI-Activity	5860	WMI temporary event consumer
WMI-Activity	5861	WMI permanent event consumer

WMI Lateral Movement Process Chain

Source Host:                    Destination Host:
wmic.exe                  -->  WmiPrvSE.exe
  process call create            -> cmd.exe /q /c <command>
                                    -> 1> \\127.0.0.1\admin$\__<timestamp> 2>&1

Key Detection Patterns

Pattern	Indicator	MITRE
WmiPrvSE -> cmd.exe	Remote command execution	T1047
WmiPrvSE -> powershell.exe	Remote PowerShell via WMI	T1047
cmd.exe /q /c ... admin$	WMI output redirection	T1047
Event 5861 consumer	WMI event subscription persistence	T1546.003
wmic process call create	Direct WMI process creation	T1047

Suspicious Child Processes of WmiPrvSE.exe

Process	Risk Level	Context
cmd.exe	High	Command execution
powershell.exe	High	Script execution
mshta.exe	Critical	HTA script execution
cscript.exe	High	VBScript/JScript
regsvr32.exe	High	COM object registration
rundll32.exe	High	DLL execution

Command Line Regex Patterns

# WMI remote execution via cmd
r"cmd\.exe\s+/[qQ]\s+/[cC]"

# Output to admin$ share
r"\\\\127\.0\.0\.1\\admin\$\\__\d+"

# WMIC process creation
r"wmic\s+.*process\s+call\s+create"

Sysmon Event 1 Key Fields

Field	Description
Image	Full path of created process
ParentImage	Full path of parent process
CommandLine	Process command line arguments
User	Account that created the process
ProcessGuid	Unique process identifier
ParentProcessGuid	Parent process identifier
