### Context
The execution of a malicious script on the compromised machine indicates the attacker has transitioned from initial access to active exploitation. The script appears to have been designed to establish persistence and further compromise the system.

### Insights
- The script likely downloaded additional payloads or modified system settings to evade detection.
- The origin of the script should be traced, possibly exploiting a known vulnerability or an unpatched system.

### Next Steps
- **Contain**: Isolate the compromised machine to prevent further lateral movement.
- **Analyze**: Reverse-engineer the script to understand its functionality and objectives.
- **Plan**: Prepare for potential persistence mechanisms being activated.
