📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

An authenticated attacker gains SYSTEM/administrator privileges on the local machine, enabling complete system compromise, data theft, persistence installation, and lateral movement.

🟠

Likely Case

Local authenticated user elevates to administrator privileges to install malware, modify system settings, or access protected resources.

🟢

If Mitigated

With proper access controls and patching, impact is limited to failed privilege escalation attempts with audit logging.
