### Context
Post detection of suspicious WMI activity, an investigation was launched to determine the scope and impact of this persistence strategy.

### Findings
- **WMI Usage**: The attacker leveraged WMI to establish persistence, likely by creating event subscriptions to execute malicious scripts upon specific triggers.
- **Scope**: This activity is consistent with tactics used by Volt Typhoon, indicating a sophisticated threat actor.

### Recommendations
- **Hardening**: Disable unnecessary WMI services and restrict access to only authorized personnel.
- **Detection**: Employ advanced monitoring to detect new WMI event subscriptions or alterations to existing ones.

### Next Steps
Prepare for potential lateral movement, as WMI activity often precedes such actions. Monitor for changes in network configurations or unusual remote access attempts.
