detecting-wmi-persistence

Detect WMI event subscription persistence (MITRE T1546.003) by analyzing Sysmon Event IDs 19, 20, and 21 for malicious EventFilter, EventConsumer, and FilterToConsumerBinding creation, cross-referenced against root\subscription namespace contents and Sysinternals Autoruns. Use when hunting WMI-based persistence, triaging a Sysmon alert on these event IDs, or during incident response and purple-team validation of WMI defenses.

# Detecting WMI Persistence

## When to Use

- When hunting for WMI event subscription persistence (MITRE ATT&CK T1546.003)
- After detecting suspicious WMI activity in endpoint telemetry
- During incident response to identify attacker persistence mechanisms
- When Sysmon alerts trigger on Event IDs 19, 20, or 21
- During purple team exercises testing WMI-based persistence

## Prerequisites

- Sysmon v6.1+ deployed with WMI event logging enabled (Event IDs 19, 20, 21)
- Windows Security Event Log forwarding configured
