API Reference — Hunting for Persistence via WMI Subscriptions

Libraries Used

subprocess: Execute WMIC and PowerShell commands for WMI enumeration
python-evtx (Evtx): Parse Sysmon EVTX for WMI-related events (IDs 19, 20, 21)
re: Pattern matching for suspicious WMI consumer payloads

CLI Interface

python agent.py enumerate                  # WMIC-based WMI subscription enumeration
python agent.py powershell                 # PowerShell Get-WMIObject enumeration
python agent.py sysmon --evtx-file <path>  # Scan Sysmon EVTX for WMI events

Core Functions

`enumerate_wmi_subscriptions()`

Queries four WMI subscription classes via WMIC and flags entries matching suspicious patterns.

Returns: dict with classes (EventFilter, EventConsumer, ActiveScriptEventConsumer, FilterToConsumerBinding) and suspicious list.

`scan_sysmon_wmi_events(evtx_file)`

Parses Sysmon EVTX for Event IDs 19 (WmiEventFilter), 20 (WmiEventConsumer), 21 (WmiEventBinding).

Parameters:

Name	Type	Description
`evtx_file`	str	Path to Sysmon .evtx file

`query_powershell_wmi()`

Uses PowerShell Get-WMIObject to enumerate WMI subscriptions in root\Subscription namespace.

WMI Classes Enumerated

Class	Description
`__EventFilter`	Defines the WQL query that triggers the subscription
`CommandLineEventConsumer`	Executes a command when the filter matches
`ActiveScriptEventConsumer`	Runs VBScript/JScript when the filter matches
`__FilterToConsumerBinding`	Links a filter to its consumer

Sysmon Event IDs

Event ID	Description
19	WmiEvent - Filter activity detected
20	WmiEvent - Consumer activity detected
21	WmiEvent - Consumer-to-filter binding

Dependencies

pip install python-evtx  # Optional, for EVTX parsing
